A new genus and six new species of the family Gomphodesmidae from the Udzungwa Mts are described, including Pogoro alopias Rosenmejer & Enghoff sp. nov., Pogoro siren Rosenmejer & Enghoff sp. nov., Pogoropsis prolixopes Rosenmejer & Enghoff gen. et sp. nov., Emphysemastix frampt Olsen & Enghoff sp. nov., Agrophogonus hamulus Olsen & Enghoff sp. nov., and Agrophogonus pusillokiellandi Olsen & Enghoff sp. nov. Emphysemastix dracarys Olsen & Enghoff sp. nov. from Iringa city is described. Descriptive notes are given for Pogoro scharffi Hoffman, 2005, and Agrophogonus mwanihana Hoffmann, 2005. General gomphodesmid gonopod morphology is described and illustrated. A key to Udzungwa gomphodesmids is presented, as well as revised keys to all species of Emphysemastix and Agrophogonus. All gomphodesmid species from the Udzungwa Mts are mapped.
A large, newly collected material of the genus Aquattuor from the Udzungwa Mts, Tanzania, has been studied. Two new species are described, viz., A. mollilobus sp. nov. from the Udzungwa Mts and A. nguruensis sp. nov. from the Nguru Mts, Tanzania. Aquattuor claudiahempae Enghoff & Frederiksen, 2015, is recorded as new for the Udzungwa fauna. Characters from the first pair of male legs are illustrated for all Aquattuor species and are shown to be useful for species discrimination. A new gonopodal difference between A. submajor Enghoff, 2015 and A. udzungwensis Enghoff, 2015 is described and illustrated. Intrageneric relationships and distribution patterns are discussed. A distribution map and a key to all Aquattuor species are presented.
Antoinettia, new genus (Coleoptera: Erotylidae: Erotylinae: Tritomini), is erected for three species: A. audbala (Skelley), new combination, A. huhnei Skelley, new species, and A. kovariki (Skelley), new combination. A genus complex involving Ischyrus Lacordaire, 1842, and Megischyrus Crotch, 1873, is defined and a preliminary key to neotropical genera of Tritomini with coarsely facetted eyes is presented.
The genus of Neotropical frogs Pithecopus includes 11 species occurring east of the Andes from southern Venezuela to northern Argentina. Recent genetic approaches pointed out an unusual genetic diversity among populations from localities in north-eastern Brazil recognized as P. nordestinus. In fact, one of these studies confirmed the hypothesis that the São Francisco River acted as an effective geographical barrier during vicariant events in the evolutionary history of P. nordestinus, resulting in two principal, highly divergent clades. Herein we formally describe this divergent clade as a new cryptic species of Pithecopus from north-eastern Brazil, the sister clade of P. nordestinus. It differs from other species of Pithecopus, except for P. azureus and P. nordestinus, by its small body size, lack of the reticulate pattern on flanks, smaller head width, and advertisement calls generally composed of a three-pulsed core.
A new cypridopsine genus, Cyprettadopsis gen. nov., described here, is principally characterized by the reduced caudal ramus, the strongly serrated claw G2 of the antenna (A2), the A2 subquadrate terminal segment, the undivided penultimate segment of the second thoracopod (T2), the morphology of the third thoracopod bearing a distinctly separated terminal segment, the complete septa on the posteroventral margin and the incomplete septa on the anterior margin of both valves. Based on a combination of these characters, a new tribe, Cyprettadopsini trib. nov., is created in the subfamily Cypridopsinae Kaufmann, 1900 to accommodate this new genus, and one new species, Cyprettadopsis sutura gen. et sp. nov., is described as the type species. Apart from the above generic characters, the following features are also typical of the new species: the tiny needlepoint-like pores along the anterior and ventral margins of both valves, the remarkably large β-seta on the mandibular palp and the considerably short d2 seta on the T2. The presence of marginal septa in the new genus is a distinctive character and constitutes the first record of this feature within Cypridopsinae. The taxonomically relevant characters in the new taxon and related taxa are briefly discussed.
A new species of Limnophilinae (Diptera: Limoniidae), Dicranophragma (Brachylimnophila) relictum Mederos sp. nov., is described. This is the third species of this genus recorded from the Iberian Peninsula. This new species was discovered in a cave in the Sant Llorenç del Munt i Serra de l’Obac Natural Park, Barcelona Province (Catalonia) and it is the first record of a species of this genus from a hypogeous environment. The absence of suitable ecological conditions for the survival of this new species, particularly in the vicinity of the cave, suggests that this population of D. relictum Mederos sp. nov. is isolated. Dicranophragma relictum Mederos sp. nov. is characterized by the following features: a general grey-to-greenish-grey coloration on its thorax and a dark-grey abdomen; wings more than four times longer than wide; pale-brown-to-yellowish tinted wings, with brown veins and a well-marked stigma; in the male genitalia the upper part of the aedeagus is acute when viewed laterally and is longer than the lower part. A key is provided for separating the three species of Dicranophragma known to be present in the Iberian Peninsula.
A new genus and species, Richerius marqueti gen. et sp. nov., of a crab of the family Hymenosomatidae MacLeay, 1838 are described from the inland waters of New Caledonia based on several specimens collected in two streams at altitudes of 180 m and 500 m, respectively. Richerius marqueti gen. et sp. nov. was compared to the other freshwater species known in New Caledonia, Odiomaris pilosus (A. Milne-Edwards, 1873), and to species of Amarinus Lucas, 1980, a genus comprising many freshwater species in New Zealand, Australia, Indonesia, the Philippines, and Papua New Guinea, but never recorded in New Caledonia. The barcode fragment of the COI mitochondrial gene was sequenced for seven specimens of R. marqueti gen. et sp. nov., and all sequences were deposited in GenBank. A brief and updated review of the New Caledonian marine and freshwater hymenosmatid fauna is provided.
A new genus, Janzena (Erebidae), and 37 new species of Noctuoidea (Lepidoptera) are described from Florida as well as two species elevated from synonymy to species status. Bleptina biformata, Bleptina extincta, Bleptina flavivena, Bleptina verticalis, Lascoria coma, Janzena pyraliformis, Sigela sordes, Sigela minuta,Sigela incisa, Sigela subincisa, Sigela rosea, Sigela lynx, Dyspyralis ocala, Metalectra nigrior, Metalectra dixoni, Melipotis florida, Doryodes acta, Doryodes unica, Doryodes fulva, Toxonprucha killamae, Zale lafontainei,Zale vargoi, Zale clandestina, Athyrma fakahatchee, Antiblemma perva, Antiblemma carolae, Paectes hercules,Meganola georgei, Litoprosopus linea, Tripudia calusa, Catabenoides insularis, Neogalea caracara, Condica collaris, Homophoberia australis, Diastema leo, Pyreferra slotteni, and Leucania elephas are described as new. Hemeroplanis floccalis (Zeller), revived status, is raised to species status from the synonymy of Hemeroplanis scopulepes (Haworth),and Euscirrhopterus argentata (Druce), revived status, is raised to species status from the synonymy of Euscirrhopterus poeyi Grote. The genus Araeopteron Hampson is restricted to the Old World and Araeopteron vilhelmina (Dyar) is transferred to the genus Sigela Hulst, new combination. The barcode index number (BIN) is provided for each species, when available.
A new genus and species of Sternaspidae (Annelida: Polychaeta) from the deep eastern Atlantic
(2020)
Based on specimens recently collected in sediments from 2700 m depth off Mauritania (Northwest Africa; type locality) and from 2700–4400 m depth off Angola (Southwest Africa), a new genus and species, Mauretanaspis longichaeta gen. et spec. nov., is described. The new genus and species are characterized by a unique combination of characters: ventro-caudal shield covered by firmly adhering sediment, lateral margins strongly bent and merging into integument; introvert hooks tapering; eight pre-shield segments; absence of peg chaetae; exceptionally long posteriormost lateral chaetae equaling body length; posterior shield chaetae equaling shield length. A comparative table of characters for all currently recognised sternaspid genera and a key to all species with ventro-caudal shield covered by firmly adhering sediment are provided.
A new genus of Baetidae is described from Southeast Asia, Procerobaetis gen. nov. It has a wide distribution reaching from Indonesia (Sumatra) to the Philippines. Two new species are described from Indonesia, P. leptobranchius gen. et sp. nov. and P. petersorum gen. et sp. nov., and one new species from the Philippines, P. freitagi gen. et sp. nov. Procerobaetis gen. nov. is characterized by having seven pairs of elongate, apically pointed gills. At least gills I and II are very slender with strongly extended points, which is unique in Baetidae. Similar gills were described from Leptophlebiidae. Procerobaetis gen. nov. is further characterized by having long, slender legs with extended, slender and slightly bent claws. The antennae posess remarkable spines at the outer, lateral margin, which are maximally developed on segments IX–XI of the flagellum. No spines are present on the posterior margins of abdominal tergites I–VI. COI sequences were obtained from all three of the new species. The genetic distances (Kimura 2-parameter) between these species are between 13% and 20%. Very limited genetic distances of 0% to 1% were found between specimens of the same species. The occurrence of two different species in the same area of Sumatra is discussed.
Recent samplings in cavities of the Iberian Peninsula led to the discovery of a new millipede species of the order Callipodida in one cave in the region of El Bierzo (León, Spain): Lusitanipus xanin sp. nov. In additional samplings (near that cave), more specimens of this new species were discovered in surface habitats. The species has various distinctive characteristics, such as its green colour, but the morphology of the gonopod has several similarities with that of Lusitanipus alternans (Verhoeff, 1893), indicating a close relationship between them. The diagnosis of the genus Lusitanipus Mauriès, 1978 has to be changed to accommodate the new species. The presence of crests in two different sizes is no longer a diagnostic character of the genus Lusitanipus, but of the species L. alternans. Lusitanipus xanin sp. nov. is the fourth species of the order Callipodida for the Iberian Peninsula, and the second species for the genus. Lusitanipus xanin sp. nov. seems to be an epigean but troglophile species.
A new microscopic cnidarian is described, infecting five of thirty (16.6%) specimens of Corydoras schwartzi caught in the Purus River, State of Amazonas, Brazil. Histological analysis showed that cyst development occurred in the serosa layer of the intestine. Mature myxospores are ovoid in body shape in frontal view, 22.4 ± 0.3 μm in total length and 16.3 ± 0.1 μm in width. Internally, two aubergine-shaped, elongate symmetrical polar capsules occupy more than half the length of the spore, 14.3 ± 0.2 μm in length and 6.5 ± 0.1 μm in width. Ultrastructural analysis provided evidence of five polar filament coils inside the polar capsule and binucleated sporoplasm containing a moderate number of sporoplasmosomes. The valvogenic cells abutting each other form a sutural ridge and frequently a thin layer of homogeneous material separates the cells. The outer surface of the myxospore valves is smooth, with no evidence of formation of ridges in the valves. Immature myxospores in various stages of development were observed. This study is the first report of a myxosporean parasitizing C. schwartzi and the first report of a myxosporean infection in the intestine of an ornamental fish from South America.
The branchial parasitic isopod Pleurocryptella altalis sp. nov. (Bopyridae: Pseudioninae) is described from the squat lobster host Munidopsis petalorhyncha Baba, 2005. The new species is morphologically similar to Pleurocryptella formosa Bonnier, 1900 and P. wolffi Bourdon, 1972b but can be distinguished based on male characters (differences in head, pleon and uropods) and female characters (differences in barbula, pleopods and pleotelson). The parasite specimens (a female and male pair) were collected with the squat lobster host at a depth of 5060–5130 m from the Kuril-Kamchatka Trench, representing the deepest record for any of the 850+ described bopyrid isopod species and for any record of an infested host. Dichotomous identification keys to females and males of Pleurocryptella species and subspecies are provided.
A new species of praying mantis, Vates phoenix sp. nov. (Mantidae, Vatinae), is described from localities within Rio de Janeiro and São Paulo states, Brazil. This is the first record of Vates from the Atlantic Rainforest biome. The new species is unique among its congeners in having, among other features, strongly reduced cuticular projections above the lateral ocelli, structures otherwise well developed and produced in all other species of Vates. Remarks on the natural history and biogeography of Vates, in relation to this new finding, are further discussed.
We review the species of Bidessus of Madagascar and describe Bidessus anjozorobe sp. nov. from material collected in Anjozorobe forest. Anjozorobe is part of the Anjozorobe-Angavo Protected Area, which is an important corridor of transition forest between typical eastern humid forests and the residual sub-humid forest of the Central Highlands. Bidessus longistriga Régimbart, 1895 and Bidessus perexiguus Kolbe, 1883 are widespread but endemic low-altitude species on Madagascar. Bidessus nesioticus Guignot, 1956 is an alpine species described from near the peak of the Ankaratra mountain massifs at 2500 m a.s.l. We recollected the species for the first time since its description, in Ankaratra and in a new area above 2000 m a.s.l. in the Andringitra mountain further south. Bidessus cf. nero Gschwendtner, 1933 is tentatively recorded for Madagascar for the first time but further studies are needed to test the status of mainland and insular populations. Bidessus apicidens Biström & Sanfilippo, 1986 has not been recollected on Madagascar since 1970. All species are endemic to Madagascar except potentially Bidessus cf. ceratus and Bidessus cf. nero described from Uganda and the Democratic Republic of the Congo, respectively. The older records of the two non-endemic species Bidessus complicatus Sharp, 1904 and Bidessus ovoideus Régimbart, 1895 on Madagascar could not be verified.
Chaetopterus is a globally distributed genus of marine Annelida with a long history of taxonomic confusion. Here, we describe Chaetopterus bruneli sp. nov. from a depth of 350 m in the St. Lawrence Estuary, eastern Canada. The new species represents the northernmost record for Chaetopterus in the western Atlantic to date. The similar European species Chaetopterus norvegicus M. Sars, 1835 is resurrected from long-standing synonymy and redescribed from type material, and a lectotype is designated.
Crioprosopus baldwini Eya (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini), sp. nov., from Costa Rica and Panama, is described. An amendment to the key to species of Crioprosopus Audinet-Serville, 1834, as presented in Eya (2015), is provided along with illustrations of the key characteristics to differentiate C. baldwini from other species.
A new species, Cryptomonas uralensis Martynenko, Gusev, Kulizin & Guseva sp. nov., is described from western slopes of the Ural Mountains (Russia) based on morphological and molecular data. Phylogenetic relationships inferred from nuclear SSU and LSU rDNA sequences show that the new species forms a clade with C. tetrapyrenoidosa Skuja emend. Hoef-Emden & Melkonian. Comparison of secondary structures of nuclear rDNA ITS2, including analysis of Compensatory Base Changes (CBC), confirms the separation between C. uralensis sp. nov. and C. tetrapyrenoidosa. Cell morphology and sizes of C. uralensis sp. nov. are very similar to C. tetrapyrenoidosa and C. pyrenoidifera, and C. uralensis sp. nov. may thus represent a species that can only be reliably identified using molecular data.
Diolcus thomasi Eger new species (Hemiptera: Heteroptera: Scutelleridae: Pachycorinae), is described from Cayman Brac and Little Cayman Island and compared to D. chrysorrhoeus (Fabricius), its closest congener. Nesogenes boscii (Fabricius) is removed from the Elvisurinae and placed in the Pachycorinae. The relationship of N. boscii to D. thomasi and D. chrysorrhoeus is discussed.
Oncotophasma aurantiaviridiata Murcia, Cadena-Castañeda, and Silva new species (Phasmida: Diapheromeridae)from the Colombian Andes is described. The new species is distinguished by its peculiar coloration, which highlights greenish and orange tones. It is also the first record of the genus for the eastern slope of the Colombian Andes. The previous distribution recorded for the genus is the Chocó biogeographic region from Costa Rica to Colombia, with species being found in the Colombian areas of influence of this biogeographic region, such as the western and central slopes of the Andes.
A new species of tortoise beetle from the north-central United States, Parorectis arenaria new species (Coleoptera: Chrysomelidae: Cassidinae: Cassidini), is described and illustrated. Comparative remarks and a key are provided to distinguish the new species from the three other species comprising the genus. Adults and larvae of the new species feed on Physalis L. (Solanaceae). The circum-foraminal ridge and antennal groove of the prothorax are described in detail. The pars stridens (file) of the stridulatory apparatus on the male cranium of the new species is illustrated. The pars stridens is present only in males of Parorectis Spaeth species. A patch of spicules is located centrally on the dorsal surface of the cranium in both males and females of Parorectis. The spicule patch is believed to function as a head-to-body binding patch.
Pteroplatus antonkozlovi Santos-Silva and Botero, sp. nov. (Coleoptera: Cerambycidae) is described from Panama. Neocompsa thelgema Martins,1971 is recorded from Panama, and chromatic variation is discussed.The female of Icimauna aysa Martins and Galileo,1991 is described. Some corrections in a recently published work on Acanthoderini are provided, and the combination Scythropopsis pupillata (Bates,1880) is established as having precedence over the simultaneously published combination Aegomorphus pupillatus (Bates,1880).
A new species of snail-eating snakes of the genus Pareas Wagler, 1830 is described from the eastern Himalayas. The species Pareas kaduri sp. nov. differs from all known species of the genus in bearing the following suite of characters: SVL 455–550 mm, TaL/TL 0.184–0.207, brown dorsum with black transverse bands throughout the body, 15 dorsal scale rows throughout the body and mid-dorsal vertebral scale rows enlarged, 8 rows keeled in males, loreal not touching orbit, ventrals 160–183, subcaudals 65–70 in males, 52 in one female specimen, hemipenis short, unilobed and 6–7 maxillary teeth. Molecular data for mitochondrial 16S rRNA and cytochrome b genes further attest the distinctness of the new species, which was recovered as a member of the Pareas hamptoni clade. Our work brings the total number of species recognized within the genus Pareas to 20.
A new symbiotic species of liljeborgiid amphipods, Liljeborgia associata sp. nov., is described from the burrows of the spoon worm Urechis unicinctus (Drasche, 1880) (Annelida: Polychaeta: Echiura: Urechidae) in the southern part of Peter the Great Bay and Posjeta Bay in the Sea of Japan. The new species is mostly similar and probably related to Liljeborgia geminata Barnard, 1969, known from the Californian coasts of the USA, and Liljeborgia serratoides Tzvetkova, 1967, described from Posjeta Bay in the Sea of Japan, but can be clearly distinguished from all congeners by morphological features of mouthparts, appendages and telson. The new species is only the fourth in the family Liljeborgiidae to be described from the Russian coast of the northwestern Pacific and the first in association with spoon worms (Echiura).
We describe a new species of the genus Zhangixalus Li, Jiang, Ren & Jiang, 2019 from Ha Giang Province, Vietnam based on morphological and molecular data. In the molecular phylogenetic analyses, the new species is nested in the Zhangixalus duboisi (Ohler, Marquis, Swan & Grosjean, 2000) group, where it is sister to Z. duboisi with a genetic distance of 2.51%. The new species, Zhangixalus franki sp. nov., differs from its congeners by a combination of the following morphological characters: size large, SVL 77.9–85.8 mm in males; finger webbing formula I1-1II0-1III½-0IV; dorsal surface of head and body green with dark brown spots; ventral surface grey or dark grey, white stripe along edge of jaw, insertion of limbs, and along lateral ridges of fore and hind limbs and flank, separating upper green part from lower grey part. The new species occurs in evergreen montane tropical forests at an elevation of ca 1300 m a.s.l. The new discovery brings the total number of known species in the genus Zhangixalus to 38 and the species number reported from Vietnam to nine.
Over the past decade, a previously unrecorded spittlebug of the genus Clastoptera Germar (Hemiptera: Cercopoidea: Clastopteridae) has been observed in abundance on oaks (Quercus L. spp., Fagaceae) in several Florida counties. We describe this spittlebug as a new species, Clastoptera querci Thompson, Halbert and Rothschild, new species, provide information on its life history, host plants and distribution, and place it in the context of other members of the genus. Clastoptera spp. can transmit Xylella fastidiosa Wells et al., a bacterial pathogen that causes bacterial leaf scorch associated with oak decline. Thus C. querci should be monitored as a possible vector of X. fastidiosa in oaks.
This paper describes a novel species of the genus Heterophoxus Shoemaker, 1925 from Brazil. The material examined was collected during the Mini Biological Trawl Project, off southeast and southern Brazil's coast off the states of Rio de Janeiro, Santa Catarina, and Rio Grande do Sul, ranging in depth from 25 to 128 meters. The new species, H. shoemakeri sp. nov., is similar to H. videns K.H. Barnard, 1930; however, the former species can be distinguished by: pereopod 7 basis posterior margin serrate with acute teeth, merus posterior margin not produced; epimeral plate 3 posteroventral corner with a longer acute projection, posterior margin almost straight; uropod 3 outer ramus article 2 clearly notable in both sexes. For Brazilian waters, this is the second record of the genus and the first species described with type material from the country. Besides that, we provide an identification key for the world species of Heterophoxus and a distribution map for the new species.
Nothochodaeus marsupialis Paulsen, new species (Coleoptera: Ochodaeidae), is described from Aceh Province, Indonesia, on the island of Sumatra. The species possesses deep abdominal cavities behind a shield-like central process, as well as rows of conical tubercles laterally on the second and third ventrites. These structures have not been found in any other members of the genus or family.
The Colaspis suilla species group (Coleoptera: Chrysomelidae: Eumolpinae) is defined relative to other species of the genus Colaspis Fabricius occurring in the United States. The group is composed of five species, of which three from Florida are described as new species: C. ansa Riley from the Florida Panhandle, C. skelleyi Riley from Central Florida, and C. thomasi Riley from the southern Lake Wales Ridge. Colaspis suilla borealis Blake is reduced to a full synonym of C. suilla Fabricius, new synonymy. Comparative remarks, habitus images, images of male and female genitalia, range maps, specimen data, and a key to species are presented.
Indian spider species currently assigned to Storena Walckenaer, 1805 are revised mostly based on the type material available in the National Zoological Collection, Zoological Survey of India, Kolkata. A new genus, Laminion gen. nov. is proposed to include four species; three are transferred from Storena: Laminion arakuensis (Patel & Reddy, 1989) gen. et comb. nov., Laminion birenifer (Gravely, 1921) gen. et comb. nov. and Laminion debasrae (Biswas & Biswas, 1992) gen. et comb. nov., whereas the fourth species is from Suffasia Jocqué, 1991: Laminion gujaratensis (Tikader & Patel, 1975) gen. et comb. nov. The species Storena tikaderi Patel & Reddy, 1989 syn. nov. is synonymised with L. birenifer gen. et comb. nov. Storena dibangensis Biswas & Biswas, 2006 and Storena indica Tikader & Patel, 1975 are transferred to Mallinella Strand, 1906. All the type material examined are imaged and redescribed. In addition, images of the type material of Storenomorpha joyaus (Tikader, 1970) are presented.
The Nearctic species of Fornax Laporte are reviewed. Three species are redescribed, and six new species are described mainly from southeastern United States. The new species are F. appalachiensis, F. convexicollis, F. floridana, F. lucidicollis, F. melsheimeri and F. parallelicollis. A neotype is designated for Hylochares bicolor Melsheimer, with notes on its purpose. Each species is diagnosed and imaged. A new identification key is provided for all known species of Fornax present in the Nearctic region, replacing previous Nearctic species keys of Muona (2000) and Otto (2017).

The division of the genus is discussed and five species groups are established. The majority of the new species are the first records of Cissidium for the 28 countries represented.
The genus Rudolfina Roháček, 1987 is revised and redefined with the description of the following nine new species, all from the New World: R. bucki sp. nov. (Mexico), R. exuberata sp. nov. (widespread, from USA to Brazil), R. howdeni sp. nov. (Mexico), R. megepandria sp. nov. (Mexico), R. newtoni sp. nov. (Mexico), R. pauca sp. nov. (Guatemala, Mexico), R. pilosa sp. nov. (Mexico), R. remiforma sp. nov. (Mexico) and R. tumida sp. nov. (Mexico, USA). Rudolfina is compared to closely related genera in the Archiceroptera genus complex, which in turn is recognized as part of a large, mostly Neotropical clade including Robustagramma Marshall & Cui, 2005, Pterogramma Spuler, 1924, Aptilotella Duda, 1924, Bitheca Marshall, 1987, Bromeloecia Spuler, 1924 and Archiceroptera Papp, 1977.
Features of the Maechidiini (Scarabaeidae: Melolonthinae) genera Maechidius Macleay, 1819, Epholcis Waterhouse, 1875 and Paramaechidius Frey, 1969 are critically revised and a new synonymy is proposed: Maechidius = Epholcis syn. nov. = Paramaechidius syn. nov. A key to and an annotated checklist of Maechidiini from the Indo-Australian transition zone are presented for the first time. Thirty-five new species are described, namely Maechidius aiyura sp. nov., M. alesbezdeki sp. nov., M. awu sp. nov., M. babyrousa sp. nov., M. bintang sp. nov., M. boessnecki sp. nov., M. brocki sp. nov., M. caperatus sp. nov., M. ciliatus sp. nov., M. crypticus sp. nov., M. dani sp. nov., M. deltouri sp. nov., M. dendrolagus sp. nov., M. hamatus sp. nov., M. kazantsevi sp. nov., M. konjo sp. nov., M. lapsus sp. nov., M. legalovi sp. nov., M. leucopsar sp. nov., M. longipes sp. nov., M. mailu sp. nov., M. maleo sp. nov., M. merdeka sp. nov., M. miklouhomaclayi sp. nov., M. nepenthephilus sp. nov., M. owenstanleyi sp. nov., M. riedeli sp. nov., M. similis sp. nov., M. skalei sp. nov., M. sougb sp. nov., M. suwawa sp. nov., M. trivialis sp. nov., M. ursus sp. nov., M. weigeli sp. nov. and M. yamdena sp. nov. Six new synonyms are proposed: Maechidius Macleay, 1819 = Epholcis Waterhouse, 1875 syn. nov. = Paramaechidius Frey, 1969 syn. nov., Maechidius esau Heller, 1914 = M. setosus Moser, 1920 syn. nov. = M. setosellus Frey, 1969 syn. nov., Maechidius heterosquamosus Heller, 1910 comb. rest. = Paramaechidius clypeatus Frey, 1969 syn. nov. and Maechidius paupianus Heller, 1910 = M. arrowi Frey, 1969 syn. nov. The first records of Maechidiini from the Tanimbar Islands (Yamdena), Sangihe Islands (Sangir) and Lesser Sunda Islands (Bali) are documented, of which the latter two are the northern- and westernmost known records of Maechidius and of the tribe Maechidiini. Lectotypes are designated for 23 species. Fifteen new combinations are proposed and the original combination to Maechidius is restored for four species. Ecological data are presented for the first time for selected Papuan and Wallacean species. Type material of Wallacean and Papuan Maechidiini is depicted for the first time. A key to species is given. In total, 78 species of Maechidiini are confirmed for the Indo-Australian transition zone.
Eight species of the genus Prodasineura Cowley, 1934 are recorded from Vietnam, including two newly described species: Prodasineura lancastrei sp. nov. and P. kong sp. nov. from north and central Vietnam. All species recorded are illustrated, including figures of morphological structures, and distribution maps and keys to the males and females are provided. We consider the record of P. laidlawi (Forster in Laidlaw, 1907) a misidentification and exclude it here.
For more than 100 years, behavioural biologists have extensively studied satin bowerbirds (Ptilonorhynchus violaceus) to understand the complexities of bower construction and courtship, but this research has not accounted for the ecologically important role the species plays as a seed disperser in eastern Australia. In this study, we have used a simple method involving pans of water and mirrors to collect scats from male satin bowerbirds on the Dorrigo Plateau of northeastern New South Wales. Based on seeds identified from scats collected using this method, we identify the fruits of 37 plant species in 22 families that are eaten by satin bowerbirds and show that 35 of these species germinated after passage through the digestive system of bowerbirds. This method was developed for bush regenerators to collect rainforest tree seeds that are otherwise inaccessible and/or difficult to germinate; it is applicable throughout the range of satin bowerbirds. We hope the method will be adopted by bush regenerators for harvesting seeds otherwise difficult to source, and by ornithologists studying the diets and seed dispersal of these ecologically significant birds.
A new giant species of the subfamily Rhynchoproctinae with strikingly bi-coloured, red-yellow legs contrasting with a black body is described: Alienostreptus bicoloripes sp. nov. from Vietnam. The new species is assigned to the genus Alienostreptus Pimvichai, Enghoff & Panha, 2010 hitherto comprising one species, A. alienus (Attems, 1936), and differing from other rhynchoproctine genera by having the femoral spine duplicated. Species of this genus share three synapomorphic characters of the subfamily, viz (1) anterior coxal fold forms deep concavity in posterior view, (2) posterior coxal fold very low, and (3) posterior coxal fold with mesal flap. A superficially very similar colourful species from Borneo, also with bi-coloured legs but clearly not belonging to Alienostreptus due to the position of ventral soft pads on male legs, is documented based on photographs.
The present study took advantage of the availability of high resolution ADS40 digital imagery to 1) systematically resample the vegetation of the Lord Howe Island Group (LHIG, excluding Ball's Pyramid); 2) conduct a numerical analysis of the floristic data; 3) map vegetation extent and the distribution of vegetation communities and 4) compare the resultant classification and mapping with those of Pickard (1983). In July 2013, a total of 86 full floristic and 105 rapid floristic sites were sampled across the island, based on a stratified random sampling design. A hierarchical agglomerative clustering strategy (Flexible UPGMA) and Bray-Curtis dissimilarity coefficient with default beta, along with nearest neighbour analysis to identify anomalous site allocations, was used to analyze the floristic data. In total 33 vegetation communities were delineated and mapped: 19 mapping units from the full floristic analysis; 7 variants identified within five of the above 19 groups; 3 mapping units from analysis of canopyonly floristic data; and 4 mapping units recognised in previous studies that are mapped but were not sampled in this survey. The resultant list of vegetation communities and non-vegetation mapping units, along with their equivalence to Pickard (1983) and DECC (2007) units, is provided. 222 plant taxa were recorded in the survey, including 47 exotic taxa. Weeds are a common component of some communities, particularly coastal strandline communities, the shrublands of the southern mountains and regenerating vegetation on landslips. The threatened plants Xylosma parvifolia, Lepidorrhachis mooreana, and Geniostoma huttonii were recorded in floristic sites. Two communities, Gnarled Mossy Cloud Forest and Lagunaria Swamp Forest are listed as Critically Endangered Ecological Communities under the NSW Biodiversity Conservation Act 2016 (BC Act). Coastal Saltmarsh, an Endangered Ecological Community listed under the BC Act, also occurs on the main island. An assessment of the conservation status of the vegetation communities recognised in the present study is provided. A number of communities warrant further consideration for listing as threatened ecological communities. Significant improvement in vegetation community attribution and spatial resolution was possible with the highresolution digital imagery, however Pickard's 1983 classification and mapping was found to be a comprehensive and accurate description of the island’s vegetation considering the imagery available at the time. This project has resulted in greatly improved accuracy of vegetation mapping linework for the LHIG. The Pickard (1983) vegetation map comprised 321 individual polygons, whereas the new map includes 1 840 polygons of sufficient accuracy to support detailed environmental planning programs, particularly within the Settlement area where spatial accuracy in the delineation of native vegetation is critical. The new vegetation communities were applied to the updated linework to complete the project. Detailed profiles were compiled of each vegetation community for which enough information was available. These profiles should prove useful in field identification of vegetation types and the assessment of their conservation status.
Neogene (Siwalik-aged) deposits from India and Pakistan have yielded many vertebrate fossils, of which most were named during the 19th century, including numerous geoemydid turtles. In contrast to many other faunal components from the Siwaliks, geoemydids have not undergone taxonomic revision for more than a century and most fossils have therefore been believed to correspond to recent taxa. In this study, we conduct a taxonomic revision of all previously described geoemydid material from the Siwalik-age. We propose that all specimens of 'Clemmys' from the Siwaliks of Punjab, Pakistan should be identified as Melanochelys sivalensis comb. nov.; that Melanochelys tricarinata var. sivalensis represents a valid species, for which we propose the replacement name Melanochelys tapani to avoid homonymy; that specimens originally identified as Batagur cautleyi and Pangshura flaviventer cannot be identified beyond the generic level; and that many fragmentary palatochelydians cannot be identified to any particular species or genus due to the lack of preserved diagnostic osteological characters. With a few exceptions, the Siwalik fauna mostly corresponds in its distribution to that of the recent fauna, indicating a certain amount of geographic stasis. However, as the stratigraphic provenance of most material is poor, it is not possible to discern meaningful temporal patterns.
The catalogue of species-group names of nine coprine genera (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini), published earlier this year, is updated and revised. Presented are species-group taxa overlooked in compiling the catalogue and new species-group taxa described in 2020, i.e. after the cut-off date of the catalogue.
Close-up photographs of nest entry, nest closure and prey transport taken on sandy coastal back dunes in Santa Barbara County, CA by Alice J. Abela substantiate and enhance written descriptions of these nesting behavior components in Miscophus californicus (Ashmead) [=M. laticeps (Ashmead)] (Hymenoptera: Crabronidae). Dictynidae (Dictyna Sundevall or Emblyna Chamberlin) is introduced as a new host family and host spider leg amputation is revealed for the first time for this small miscophine wasp.
We report here the results from field trips to collect Odonata in the northeastern parts of Kelantan state and the north of Terengganu state, Peninsular Malaysia. Eighty four species were collected, and four of these are new records for the state Kelantan and 10 are new records for the state of Terengganu. Notable records obtained from the field trips were Euphaea masoni, Coeliccia sameerae, Pseudagrion ?lalakense, Leptogomphus tioman and Macromia cupricincta. Checklists for Kelantan (140 species) and Terengganu (132 species) are given in an appendix.
Since 2015, 90 taxa of lichens and 18 lichenicolous fungi have been recorded from Turkey for the first time. Further 707 taxa are new to one or more provinces. In this paper 2 species are new to Turkey. A list of 82 published papers is also provided as a supplement to the bibliography of the 2017 Checklist (John & Türk (2017) of Turkish Lichens.
Although Sweden is a country with a comparatively well-known fauna, there are still many species that await discovery, especially in the boreal regions. In this study five new species of Diplazontinae, Homotropus klopfsteinae sp. nov., Homotropus hellqvisti sp. nov., Homotropus mugerwai sp. nov., Homotropus riedeli sp. nov. and Woldstedtius aureotibialis sp. nov., are described. Sussaba roberti Klopfstein, 2014 and Homotropus megaspis (Thomson, 1890) are reported for the first time from Sweden. Four of the new species are described from boreal areas, which highlights the need to further investigate the river- and seaside areas of the western taiga.
Sixteen aglaopheniid hydroids occurring in two recent, deep water collections from off New Caledonia are reported upon, of which 8 species are new, namely Cladocarpus asymmetricus sp. nov., C. partitus sp. nov., C. pennatus sp. nov., Lytocarpia fragilis sp. nov., L. pilosa sp. nov., L. pseudoctenata sp. nov., L. subtilis sp. nov. and Macrorhynchia spiralis sp. nov., the latter producing medusoid gonophores. Although not occurring in the present collections, brief notes on M. disjuncta (Pictet, 1893), including the first description of its gonosome, are provided to support its specific separation from M. phoenicea (Busk, 1852).
The assassin bug Apiomerus cazieri Berniker and Szerlip (Hemiptera: Reduviidae) was observed to prey on the clerid beetle Trichodes ornatus Say (Coleoptera: Cleridae). This observation is the first recorded instance of Trichodes Herbst as a prey insect, and the second record for reduviid predation on Cleridae.

Arcola malloi (Pastrana, 1961) is a junior subjective synonym of Macrorrhinia endonephele (Hampson, 1918) syn. nov. (Lepidoptera: Pyralidae). The species is a biological control agent introduced in United States and Australia to control alligatorweed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae). The synonymy is recognized by comparison of type specimens, genitalic dissections, and DNA COI barcoding. Vogtia Pastrana, 1961 syn. nov. and Arcola Shaffer, 1995 syn. nov. are synonymized with Macrorrhinia Ragonot, 1887. Macror-rhinia megajuxta (Neunzig and Goodson, 1992) comb. nov. is transferred from Ocala Hulst, 1892. Lectotypes are designated for Divitiaca ochrella Barnes and McDunnough, 1913, and Divitiaca simulella Barnes and Mc-Dunnough, 1913.
Dass Pflanzenarten bei aller Dynamik nicht einfach zufällig an bestimmten Orten zusammen erscheinen, sondern in wiederkehrenden und beschreibbaren Mustern, ist in der Öffentlichkeit noch immer wenig bekannt. Diese Muster werden von der Vegetationskunde seit ihren Anfängen im 19. Jahrhundert wissenschaftlich untersucht. Die Grundeinheit ist dabei die Pflanzengesellschaft oder Assoziation. Damit ist die Gesamtheit aller Pflanzenarten gemeint, die unter bestimmten biotischen und abiotischen Bedingungen regelhaft miteinander koexistieren. Um auf die Gefährdung und Schutzwürdigkeit der heimischen Pflanzengesellschaften aufmerksam zu machen, hat die Floristisch-Soziologische Arbeitsgemeinschaft (Tuexenia) für das Jahr 2019 zum ersten Mal eine "Pflanzengesellschaft des Jahres" ausgerufen (DIERSCHKE & HEINKEN 2018, TISCHEW & al. 2018). Die Wahl ist auf die Glatthaferwiese (Arrhenatheretum elatioris) gefallen, was kaum ein Zufall sein dürfte, denn Glatthaferwiesen gehören zu den buntesten und auffälligsten Pflanzengesellschaften unserer Landschaften – und sie sind im Flachland mittlerweile von vollständiger Vernichtung bedroht (FINCK & al. 2017).
Auf einer etwa 0,5 ha großen Obstwiese an der Schattbachstraße in Bochum-Querenburg/Laer wurden von Mai 2018 bis Juli 2019 Flora, Fauna und Funga soweit möglich erfasst. Die Artenliste soll als Grundlage dienen, Veränderungen in der Artenzahl und Artenzusammensetzung bei einer späteren Untersuchung analysieren zu können. Diese Veränderungen erfolgen durch die Überführung der ehemaligen Wiesenbrache mit gelegentlicher Beweidung in eine zweischürige Glatthaferwiese im Sinn einer "Historischen Wiese". Insgesamt wurden 710 Arten nachgewiesen, unter ihnen 183 Pflanzenarten (168 Gefäßpflanzen, 13 Moose, 2 Algen), 32 Pilzarten, 13 Flechtenarten und 482 Tierarten. Bei den Tieren stand die Erfassung der Insekten (400 Arten), insbesondere der Anteil der Bestäuber (158 Arten, 40 %), im Fokus. Durch die Nutzungsänderung zu einer blütenreichen Mähwiese sind in dieser Gruppe am ehesten positive Veränderungen zu erwarten. Die Bestäuber werden hinsichtlich ihrer Blütenbesuche analysiert und die wichtigsten Pflanzenarten aufgeführt, an denen sie beobachtet wurden. Dabei stellen sich neben den Obstbäumen fünf Arten der Krautschicht (Senecio jacobaea, Heracleum sphondylium, Daucus carota, Anthriscus sylvestris und Cirsium arvense) mit jeweils 20 oder mehr unterschiedlichen Bestäubern als meistbesuchte Arten heraus. Bei der Bestäubung dominieren mit 38 % Hautflügler-Arten (Hymenoptera), gefolgt von Zweiflüglern (Diptera, 26 %), Käfern (Coleoptera, 18 %) und Schmetterlingen (Lepidoptera, 18 %). Die Anteile der gefährdeten Arten mit 9 (1,7 %) (zusätzlich 9 Arten der Vorwarnliste) und der Neobiota mit 32 Arten (4,5 %, 19 Neophyten, davon 10 unbeständig, und 13 Tierarten) sind relativ gering. Die gewählten Entwicklungsmaßnahmen der Wiese, die neben der Mahd auch Einsaaten umfassen, werden erläutert und Artenzahlen sowie Erfolgsperspektiven auch vor dem Hintergrund der klimatischen Änderungen diskutiert.
Sampling of day-active invertebrates visiting the flowers of Grey Mangrove Avicennia marina subsp. australasica (Walp.) J.Everett (family Acanthaceae) was undertaken at a study site on the Harrington estuary, northern New South Wales, Australia. The study extended over a 4 season period (from 2016 to 2020), with more than 170 anthophilous species being recorded. Nearly all were observed contacting flower stigmas and/or anthers during foraging episodes. At least 113 of the approximately 168 species examined for pollen loads, carried Avicennia pollen. None carried mixed pollen loads, indicating foraging constancy/fidelity. Although pollen carriage does not automatically assign the status of pollinator, nevertheless, the findings indicate Avicennia marina is pollinated by a taxonomically diverse suite of native invertebrates which sit within an assemblage of flower visitors that may include non-pollinating species. Although the invasive honeybee Apis mellifera was seasonally common during most days of observation, it was uncommon or absent on some days. The occurrence of native flower-visiting species was often found to be episodic, with many species being abundant during one day or season of observation, but then absent or rarely encountered at other times. Such behavioral events highlight the need for extended periods of field investigation to illuminate more fully the pollination ecology of individual plant species. Comparison with additional anthophilous insect records from a previous 1990 – 1994 study in an adjacent littoral rainforest community, indicated that this community may furnish a pool of native insects from which Avicennia marina can seasonally recruit a dynamic pollinator network.
One individual referable to Calliopiidae G.O. Sars, 1893 was collected from a chemically reduced habitat, the hydrothermal vent systems in Okinawa Trough, and was identified as a new genus and species belonging to this family after a morphological examination. A formal description of this new species and a discussion of the relationship of the new genus within Calliopiidae are presented.
Three groups of beetles inhabit cones of cycads (Cycadales) in the northern hemisphere and are believed to be involved in their pollination. The primitive weevil subtribe Allocorynina (Coleoptera: Belidae) is restricted to the New World cycad genera Dioon Lindl. and Zamia L. One group of weevils (Curculionidae), found only in Cycas L., appears to be a relatively recent colonizer of northern hemisphere cycads. Members of the beetle subfamily Pharaxonothinae (Erotylidae) occur in all Asian and New World cycad genera. Phylogenetic trees of these beetles, based on DNA analysis and supported with morphological studies, are compared to patterns of continental drift and cycad phylogenies. Laurasian origins are suggested for these beetle groups with high latitude dispersal for at least one of these groups during periods of global warm climates.
Hier werden bemerkenswerte floristische Funde aus Nordrhein-Westfalen aus dem Jahr 2019 und einige Nachträge aus 2018 zusammengestellt, die aus Sicht der Schriftleitung von landesweiter Bedeutung sind. Die Funde werden im Laufe des Jahres zunächst chronologisch auf die Homepage des BOCHUMER BOTANISCHEN VEREINS gestellt und am Ende des Jahres zu einem Artikel zusammengefasst. Bei der Auswahl der Arten für diese Liste ist nicht an Bestätigung bereits lange bekannter Vorkommen gedacht, die an Ort und Stelle durchgehend vorkommen, sondern z. B. an Neufunde seltener Arten, Wiederfunde seltener Arten, die zwischendurch verschwunden schienen (wie z. B. Ackerunkräuter) oder auch an bekannte Vorkommen, die erloschen sind oder kurz vor dem Erlöschen stehen. Außerdem nehmen Beobachtungen von neophytischen Arten einen großen Raum ein, die entweder auf dem Wege der Einbürgerung sind, deren Einbürgerung noch nicht allgemein bekannt bzw. anerkannt ist oder deren Vorkommen bisher erst selten für Nordrhein-Westfalen veröffentlicht wurden. Ein wichtiges Kriterium für aufgeführte Arten ist die Selten-heit im Bundesland oder der betreffenden Großlandschaft bzw. Region. Die Zuordnung der Arten zu Pflanzenfamilien richtet sich nach PAROLLY & ROHWER 2016.
Im Folgenden werden für das östliche Ruhrgebiet bemerkenswerte Funde aufgeführt. Das Gebiet umfasst die Städte Gelsenkirchen, Essen, Herne, Bochum, Dortmund, Hagen und Hamm sowie die Kreise Recklinghausen, Unna und den Ennepe-Ruhr-Kreis. Zur besseren Auswertung sind hinter den Fundorten die MTB-Angaben (Topographische Karte 1:25000) und ggf. eine Bewertung des Fundes für den hiesigen Raum und der floristische Status hinzugefügt. Funde aus dem östlichen Ruhrgebiet, die von nordrhein-westfälischer Bedeutung sind, sind im Beitrag BOCHUMER BOTANISCHER VEREIN (2020) aufgeführt. Die Zuordnung der Arten zu Pflanzenfamilien richtet sich nach PAROLLY & ROHWER (2016).

We report 106 species of caddisflies (Trichoptera) representing 44 genera and 16 families that were collected across 50 sampling sites in the Buffalo River watershed. The species collected represent about 45% of the known Interior Highlands caddisfly fauna. The most speciose families collected were the Hydroptilidae (30), Leptoceridae (21), and Hydropsychidae (17). Two species found during this study, Paduniella nearctica and Ochrotrichia contorta, are listed as species of special concern in the state of Arkansas due to their relative rarity. Similarity analysis values among collection sites ranged from 9% to 77%. Seriation analysis of caddisfly genera and species showed that most are distributed throughout the entire Buffalo National River but some are restricted to either the upper or lower river or its tributaries. This represents the first comprehensive survey of caddisflies completed for the Buffalo National River.
The chewing louse species Lipeurus megalops Piaget, 1880, is redescribed and illustrated. This species has previously been placed in the genus Oxylipeurus Mjöberg, 1910, but marked differences in preantennal structure, male and female genitalia, abdominal chaetotaxy, and structure of abdominal plates indicate that this species is not closely related to other species in this genus. We therefore erect a new genus, Calidolipeurus gen. nov. for this species. Calidolipeurus is presently monotypic, containing only Calidolipeurus megalops gen. et comb. nov. We also provide a preliminary key to the Oxylipeurus-complex.
The recruitment processes and resulting distribution pattern of bird-dispersed Canary Island Date Palm, Phoenix canariensis (family Arecaceae) in a riverine forest setting are described. All palms on a near-urban peninsula of the Murrumbidgee River near Hay, New South Wales were GPS mapped and classified into height-dependent age categories. The distribution of the plants was examined spatially in relation to possible source palms and in relation to elevation with regard to flooding levels. Successful recruitment is subject to a range of environmental parameters, primarily palatability to vectors and seedling mortality due to lack of moisture, frost or grazing by herbivores. If a seedling survives that critical period of the first 18 months, long-term success is (almost) guaranteed, unless catastrophic events (bushfires, prolonged flooding) intervene. Based on the findings, a conceptual model for the recruitment of Phoenix canariensis palms is provided. Even though the palms produce fruit for much of the year (March–December), the time window for successful recruitment is restricted to a period from August to mid-September with short shoulder periods on either side.
Capparis macrantha Souvannakhoummane, Fici & Lanorsavanh sp. nov., a new shrub species characterized by erect or ascending habit, stipular thorns, large lanceolate-elliptic leaves and large flowers in supra-axillary rows, is described and illustrated from the deciduous forest in Nam Kading National Protected Area (central Lao PDR). The new species belongs to Capparis sect. Monostichocalyx Radlk. and is morphologically similar to C. radula Gagnep., a shrub widespread in the Indochinese area, differing in the shorter, straight stipular thorns, larger leaves, larger sepals and petals, higher number of stamens with longer filaments and longer gynophore and ovary. Its affinities with related taxa are discussed and a key is provided for the species of Capparis L. known from Lao PDR. The conservation status of the new species is provisionally assessed as Vulnerable (VU D1).
Au Tchad, à cause de ses retombées financières une attention particulière est prêtée aux arbres à karité (Vitella- ria paradoxa C.F.Gaertn.). Cependant, cette culture est menacée par les plantes vasculaires parasites de la famille des Lo- ranthaceae. La présente étude a été effectuée dans 3 sites dans la région du Mandoul pour évaluer l’ampleur des attaques de Loranthaceae (gui africain) sur des arbres en fonction des classes de circonférence du tronc à 1,5 cm du sol. Elle a consisté à dénombrer sur une de surface, les arbres à karité infestés et les touffes de parasites rencontrées sur ces arbres, afin de dé- terminer leur taux et leur intensité d’infestation. Les résultats obtenus montrent que Tapinanthus dodoneifolus (DC) Danser a été trouvée comme la seule espèce de Loranthaceae qui parasite les arbres karité étudiés dans la zone d’étude. Le taux moyen d’infestation estimé à 73% augmente avec l’âge des arbres karité. La moyenne d’intensité de l’infestation/arbre (2,75 touffes à Békôh, 2,27 à Yomi and 2,04 à Bébopen) montre que Tapinanthus dodoneifolus constitue une réelle menace pour les peu- plements de karité dans la zone d’étude. Il reste à rechercher le seuil d’infestation qui provoque une réduction significative de la fructification. Pour l’instant, bien que pénible à cause de la hauteur des arbres adultes, la lutte mécanique contre les Ta- pinanthus par la coupe systématique des branches infestées est urgente dans les parcs à karité dans cette zone d’étude.
Presented are species-group names published in the nine coprine genera (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini) having only one lateral carina on each elytron. The data include authorships, dates and pages of original descriptions, geographic distributions, and references to works pertinent to the topic.
We studied the cestode fauna (Platyhelminthes) of forest birds in Malaysia (Selangor) collected during a field trip in 2010. Ninety birds of 37 species were examined and global prevalence of cestodes was 15.3%. Five new taxa are described: Emberizotaenia aeschlii sp. nov. (Dilepididae) from Tricholestes criniger (Blyth, 1845) (Pycnonotidae); Anonchotaenia kornyushini sp. nov. (Paruterinidae) from Trichastoma malaccense (Hartlaub, 1844) (Pellorneidae); Biuterina jensenae sp. nov. (Paruterinidae) from Chloropsis cochinchinensis (Gmelin, 1789) (Irenidae); Raillietina hymenolepidoides sp. nov. (Davaineidae) and R. mahnerti sp. nov. (Davaineidae) from Chalcophaps indica (Linnaeus, 1758) (Columbidae). Ophryocotyloides dasi Tandan & Singh, 1964 is reported from Psilopogon henricii (Temminck, 1831) (Ramphastidae). Several other taxa in Dilepididae, Davaineidae, Paruterinidae, Hymenolepididae and Mesocestoididae, either potentially new or poorly known, are also reported. The richness described from this small collection hints at the potentially huge unknown parasite diversity from wild hosts in this part of the world.
Fourteen species of Chalcidoidea (Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae and Torymidae) were obtained from the common reed, Phragmites australis (Cav.) Trin. ex Steud. (Poaceae) in the Urmia region, in the northwest of Iran. Among these species, two new species of Pteromalidae are described hereafter: Norbanus persicus Lotfalizadeh & Rasplus sp. nov. and Stenomalina delvarei Lotfalizadeh & Rasplus sp. nov. Anagyrus near alienus Japoshvili, 2002, Asitus sp., Cheiloneurus paralia (Walker, 1837), Echthroplexiella obscura (Hoffer, 1952), Neococcidencyrtus poutiersi (Mercet, 1922) (all Encyrtidae), Aprostocetus orithyia (Walker, 1839) (Eulophidae), Eupelmus phragmitis Erdös, 1955 (Eupelmidae), Aximopsis deserticola (Zerova, 2004) comb. nov., Tetramesa phragmitis (Erdös, 1952) and Tetramesa sp. (all Eurytomidae), Homoporus febriculosus (Girault, 1917) (Pteromalidae) and Torymus arundinis (Walker, 1833) (Torymidae) were also obtained from our laboratory rearing. Nine of these species are recorded for the first time from Iran.
This work is the first attempt to integrate into one list and quantify all the known species of Guade loupean insects. It includes all the species known to us to be reported for the island of Guadeloupe until the 31st of December 2019. A total of 3097 valid species are listed, of which the largest component is the beetles (1447 species). Preliminarily, 632 species (20%) are considered to be strictly endemic to Guadeloupe, and 250 species are recognized as adventive or introduced. The bibliography complements the taxonomic information and includes over 350 titles. Brief annotations are also given on the history of entomology in Guadeloupe. This list includes four new island records for Guadeloupe: Azeta rhodogaster Guenée, 1852 (Lepidoptera: Erebidae), Eudocima apta (Walker, 1857) (Lepidoptera: Erebidae), Urania leilus (Linnaeus, 1758) (Lepidoptera: Uraniidae) and Micronotus quadriundulatus (Redtenbacher, 1892) (Orthoptera: Tetrigidae), all recently collected in Guadeloupe.
The present checklist covers the fauna of the Trichopteran family Rhyacophilidae Stephens, 1836. Based on extensive surveys done during 2003–2019 and previous species records, we find that the family Rhyacophilidae is represented by two genera and 184 species in India. The genus Rhyacophila Pictet contains 165 species in India while the genus Himalopsyche Banks contains 19 described species. The Indian Himalayan region is inhabited by more species than the rest of India.
Detailed description and illustrations of immature Trictenotoma Gray, 1832 (Trictenotomidae Blanchard, 1845) are presented for the first time, based on larvae and pupae of T. formosana Kriesche, 1919. Characters exhibited by the mature larva are similar to those described by Gahan (1908) for T. childreni Gray, 1832, which was based on a single specimen. The phylogenetic position of Trictenotomidae has varied among Scarabaeoidea, Chrysomeloidea and Tenebrionoidea, though recent studies place the family clearly among the latter. Features of the immature stages described here corroborate this placement. Evidence supports placement within or near the "salpingid group" (Pythidae, Salpingidae, Boridae, Pyrochroidae). Distinguishing features of the mature trictenotomid larva include the absence of stemmata, antennal sensorium, urogomphal pit(s) and lip, the presence of paired series of longitudinal ridges on the meso- and metathorax and abdominal tergites 1–8 and sternites 2–8, a paired arcuate row of 12–15 asperities on the anterior margin of sternite 9 and relatively short, upturned urogomphi. The systematic position of trictenotomids within the Tenebrionoidea Latreille, 1802 is confirmed. The phylogenetic relationships among Trictenotomidae and other “salpingid group” members (e.g., Pythidae Solier, 1834 and Salpingidae Leach, 1815) are highlighted and discussed, solving an almost two centuries old puzzle in Coleoptera systematics.
Using a qualitative sampling approach to survey for Odonata along water systems inside and outside of four major protected areas in Southern Ghana (viz; Atewa Range Forest Reserve, Ankasa Forest Reserve, Owabi Wildlife Sanctuary and Bobiri Forest Reserve), a total of 66 Odonata species in seven families encompassing 28 Zygoptera and 38 Anisoptera were recorded. Libellulidae (n= 36) exhibited the highest number of species, followed by Coenagrionidae (n= 10), and Calopterygidae (n= 5). In considering the observed number of species exhibited by each protected area, the Atewa Range Forest Reserve exhibited the highest number of species (n= 51), followed by the Ankasa Forest Reserve (n= 47), the Owabi Wildlife Sanctuary (n= 44) and Bobiri Forest Reserve (n= 43). Disturbance tolerance species dominated in habitats outside the various forest reserves, whiles forest specialists predominated inside the reserves, indicating the quality of the forest cover therein.
We describe Croton calcareus Riina & Mateo-Ram. sp. nov., a new species in Croton section Cyclostigma (dragon's blood trees) from the state of Chiapas (Mexico). This species is a small tree growing in dry forest on calcareous substrates. Both morphological and molecular data support C. calcareus sp. nov. as a new species closely related to C. redolens, another dry forest taxon from northern Venezuela. We provide illustrations, a distribution map and suggestions for species conservation status. The new species along with Croton draco are the only known representatives of C. section Cyclostigma occurring in Mexico.
Cyrtandra argentii Olivar, H.J.Atkins & Muellner sp. nov., endemic to the Philippines and named after George Argent, is herein described and illustrated. Collections associated with this new species are often confused with three other species, namely C. ferruginea Merr., C. villosissima Merr., and C. hirtigera H.J.Atkins & Cronk. Distinguishing characters including keys, updated descriptions, distribution maps, and photos of live specimens are provided to aid identification of the four species. Following the International Union for the Conservation of Nature (IUCN) criteria, C. argentii sp. nov. is considered to be Near Threatened (NT) due to its distribution in a zone susceptible to anthropogenic pressure and the lack of any formal protection.
Deep-water species from the western Indian Ocean off the East African coast and Madagascar, belonging to the subfamily Photinae, are discussed and compared with species from the West Pacific. Phos elegantissimus Hayashi & Habe, 1965, P. hirasei Sowerby, 1913 and P. laevis Kuroda & Habe in Habe, 1961 are recorded from Mozambique and/or from Madagascar, hereby extending their known range considerably into the western Indian Ocean. The East African specimens formerly assigned to Phos roseatus Hinds, 1844 are found to differ from this West Pacific species. In total, five species are described as new: Phos ganii sp. nov., P. geminus sp. nov., P. ladoboides sp. nov., P. pulchritudus sp. nov. and P. testaceus sp. nov.
A new species of Chrysina Kirby, C. clavellina Monzón, Blackaller, and Hawks (Coleoptera: Scarabaeidae: Rutelinae: Rutelini) is described from Santiago Clavellinas in the Sierra Azul in Oaxaca, Mexico. Chrysina cosijoezai (Ramírez-Ponce and Curoe) is placed as a junior synonym of C. lacordairei (Boucard), and notes on the Chrysina fauna of this mountain range are included.
Based on an integrative taxonomic approach, a new species of the genus Loxosceles Heineken & Lowe, 1832, is described from the state of Hidalgo, Mexico. Loxosceles tolantongo sp. nov. is described based on DNA barcoding using cytochrome c oxidase subunit 1 (CO1) and internal transcribed spacer 2 (ITS2), and morphology. For species delimitation, four molecular methods were implemented: 1) corrected p-distances under neighbor joining (NJ); 2) automatic barcode gap discovery (ABGD); 3) general mixed yule coalescent model (GMYC) and 4) Bayesian Poisson tree processes (bPTP). The new species morphologically resembles L. jaca, another species from Hidalgo, but there are morphological differences mainly in the tibiae of the male palp, the seminal receptacles of the females and also the high genetic p-distances. CO1 was more informative than ITS2 for the genetic separation; however, both concatenated genes (CO1 + ITS2) present robust evidence for species delimitation. Loxosceles tolantongo sp. nov. is considered a unique species for four reasons: 1) it can be diagnosed and distinguished by morphological characters (of the male palps mainly, but also of the seminal receptacles of the females); 2) the genetic p-distances with CO1 were high (>10%); 3) the molecular species delimitation methods were congruent under CO1 and CO1 + ITS2; and 4) under CO1 and CO1 + ITS2, the new species is a putative sister group of L. jaca + L. tenango.
The tribal allocation of Xalitla Lane, 1959 (Cerambycidae: Cerambycinae) is discussed. Xalitla limoni Santos-Silva and Skillman, new species,is described from Mexico (Jalisco). Xalitla lezamai Galileo and Martins,2008 is determined to be synonymous with X. genuina Martins,1970 and formally placed in synonymy. A key to the species of Xalitla, which includes the new species and synonymy, is provided.
Phlyctinus callosus (Schoenherr, 1826) (Curculionidae, Entiminae, Oosomini) is a species native to the Western Cape province of the Republic of South Africa. It is regarded as a key pest of orchards and vineyards. Detailed observations of its morphology and ecology have shown this species to be a complex of closely related species. In this study we describe the species of this complex, provide morphological and molecular diagnostic tools to distinguish between species, and review their distribution and host plant associations. In all, six species are recognized in the P. callosus complex and five are described as new (P. grootbosensis Haran sp. nov., P. xerophilus Haran sp. nov., P. planithorax Haran sp. nov., P. littoralis Haran sp. nov., P. aloevorus Haran sp. nov.). Sequences of the mitochondrial gene used (cytochrome oxidase I, COI) indicated that P. xerophilus Haran sp. nov. might comprise several cryptic species for which stable morphological features could not be identified at this stage. The species of the genus Phlyctinus appear to be primarily associated with various Asteraceae found in humid, sandy and disturbed habitats.
Description of two new genera and a taxonomic key to the world genera of Cybocephalidae (Coleoptera)
(2020)
The sixteen genera of Cybocephalidae (Coleoptera) occurring worldwide are listed and keyed. The genera included are Amedissia Kirejtshuk and Mantič, Apastillus Kirejtshuk and Mantič, Cybocephalus Erichson, Endrodiellus Endrödy-Younga, Eupastillus Lawrence, Hierronius Endrödy-Younga, Horadion Endrödy-Younga, Pacicephalus Kirejtshuk and Mantič, Pastillocenicus Kirejtshuk and Nel, Pastillodes Endrödy-Younga, Pastillus Endrödy-Younga, Pycnocephalus Sharp, Taxicephomerus Kirejtshuk, Theticephalus Kirejtshuk, a description of a new genus, Microthomas T. R. Smith, with one new species, M. brevicornis T. R. Smith, from Bolivia, and a new genus, Conglobatus T. R. Smith, with two new species, C. armatus T. R. Smith from Central and South America and C. fullertoni T. R. Smith from Dominica. A key to genera, illustrations of morphological features, and distributional data are provided. The genus Nodola Bréthes is found to be a new synonym of Cybocephalus Erichson. The transfer of Nodola chilensis Bréthes into Cybocephalus creates a secondary homonymy with C. chilensis Reitter. Nodola chilensis Bréthes is here given a new name, Cybocephalus brethesi T. R. Smith.
Two new species of Phyxelididae are described from southern Africa: Xevioso cepfi sp. nov. (♂♀), from mountains in the Niassa Province of northern Mozambique, and X. megcummingae sp. nov. (♂♀), from urban Harare, northern Zimbabwe and the Viphya Mts in Malawi. They represent the northernmost localities of the genus. An identification key, partially adapted for the new species, is presented. The biogeographical importance of the mountain areas on both sides of the northern part of Lake Malawi is discussed.
Thirteen species of Echinoderes with nearly identical spine/tube patterns, and apparently similar tergal extensions were re-examined and compared. Based on this, redescriptions and/or emended species diagnoses are provided for Echinoderes aureus, E. dujardinii, E. gerardi, E. imperforatus, E. pacificus, E. pilosus, E. sensibilis, E. sublicarum and E. worthingi, and new details about cuticular structures are added for E. kozloffi and E. gizoensis. The new information derived from the redescriptions, and the subsequent comparative studies revealed that: 1) the holotype of Echinoderes lanceolatus is identical with the types of Echinoderes aureus, and E. lanceolatus is thus a junior synonym of E. aureus; other potentially synonymous species that should be addressed further in the future include: E. dujardinii + E. gerardi; E. imperforatus + E. sensibilis, and E. pacificus + E. sublicarum; 2) the paratypes of E. lanceolatus represented a different yet undescribed species, here described as E. songae Sørensen & Chang sp. nov.; 3) a comparison with literature information about E. ehlersi showed that the species is so insufficiently described that a redescription of topotype material is required before the species should be considered for taxonomic comparison; 4) specimens from the Andaman Islands, India, that previously have been reported as Echinoderes cf. ehlersi represent two different undescribed species, of which one is described as E. chandrasekharai Sørensen & Chatterjee sp. nov. and the other is left undescribed due to the limited material available; 5) out of a total of fifteen addressed species, it is proposed that eleven represent a putatively monophyletic group that is named the Echinoderes dujardinii group. The group includes following species: E. dujardinii, E. ehlersi, E. gerardi, E. imperforatus, E. kozloffi, E. sensibilis, E. pacificus, E. sublicarum, E. songae Sørensen & Chang sp. nov., E. chandrasekharai Sørensen & Chatterjee sp. nov., and Echinoderes sp. from the Andaman Islands, and is supported by a similar spine/tube pattern (except for variation regarding the presence of lateral accessory tubes on segment 8); generally short middorsal spines, especially on segments 4 to 6; glandular cell outlets type 1 always present in middorsal positions on segments 1 to 3, and in subdorsal positions on segments 4 to 9; glandular cell outlets type 2 always present in laterodorsal or midlateral positions on segment 8, and sometimes in same positions on segment 9 but never at any other segments or positions; female papillae always present on sternal plates of segments 7 and 8, and occasionally also on segment 6; tergal extensions well-spaced, triangular, gradually tapered cones, and pectinate fringes of sternal extensions are differentiated into seta-like tufts. The comparisons furthermore showed potential taxonomic significance of two echinoderid character traits that previously have been slightly neglected as diagnostic traits, namely the presence and appearance of female papillae, and the dorsal pattern of glandular cell outlets type 1. Female papillae may occur on the sternal plates of segments 6 to 8, but the positions may differ from ventrolateral to ventromedial, and the morphology of the intracuticular substructure also differ at species level. Information about position and morphology of female papillae proved helpful for species recognition, but it might also provide information of phylogenetic importance. Analyses of glandular cell outlet type 1 patterns on the dorsal sides of segments 1 to 9 in species of Echinoderidae, revealed several apparently unique or rare patterns, but also three distinct patterns that applied to larger groups of species. One pattern is the one present in all species of the E. dujardinii group, whereas the other two common patterns included 1) middorsal outlets on segments 1 to 3, and paradorsal outlets on segments 4 to 9 (found in 27 species), and 2) middorsal outlets on segments 1 to 3, 5 and 7, and paradorsal outlets on segments 4, 6 and 8 to 9 (found in 27 species).
Micropterigidae is a family of Lepidoptera characterized by plesiomorphic morphological characters. Presently, this family consists of more than 22 genera and is distributed throughout all biogeographic realms. Vietomartyria Hashimoto & Mey, 2000 presently consists of six species mainly from South China. Two new species of the genus, V. wuyunjiena sp. nov. and V. maoershana sp. nov., are described herein from China; adult genitalia and wing venation are illustrated. Some biological accounts of the new species are also provided. A key to all described Vietomartyria species is given.
