Two new species of marine Platyhelminthes, Microstomum laurae sp. nov. and Microstomum edmondi sp. nov. (Macrostomida: Microstomidae) are described from the west coast of Sweden. Microstomum laurae sp. nov. is distinguished by the following combination of characters: rounded anterior and posterior ends; presence of approximately 20 adhesive papillae on the posterior rim; paired lateral red eyespots located level with the brain; preoral gut extending anterior to brain and and very small sensory pits. Microstomum edmondi sp. nov. is a protandrous hermaphrodite with a single ovary, single testis and male copulatory organ with stylet. It is characterized by a conical pointed anterior end, a blunt posterior end with numerous adhesive papillae along the rim, and large ciliary pits. The stylet is shaped as a narrow funnel with a short, arched tip. In addition, the first records of fully mature specimens of Microstomum rubromaculatum von Graff, 1882 from Fiskebäckskil and a phylogenetic analysis of Microstomum Schmidt, 1848 based on the mitochondrial cytochrome oxidase I (COI) gene are presented.
The frog Pristimantis marmoratus was originally described als Hylodes marmoratus by George A. Boulenger in 1900 based on a single specimen reported to have been collected at the foot of Mount Roraima in Guyana in 1898. We herein discuss the exact location of the type locality of P. marmoratus and provide a redescription of the species based on new material from Kaieteur National Park and from the slopes of Maringma-tepui in Guyana. We also describe the previously unknown vocalization and breeding ecology of the species, and conducted an exploratory molecular analysis of the phylogenetic relationships within the genus Pristimantis represented by the members of the "unistrigatus species group" in the Guiana Shield. Pristimantis marmoratus is a small-sized species mainly distinguished from its known Guiana Shield congeners by the combination of F I < II, SVL ≤ 20.4 in males, presence of vocal slits in males, granular/pustulate dorsal skin with well-developed scapular ridges, basal webbing between fingers, fringes in fingers and toes, crossed iris, diffuse yellow or pale green wash on groin, and absence of flashy colour on axillary/pre-axillary region. The advertisement call consists of a single note repeated at a rate of ca 11 calls/min with a dominant frequency ranging from 2756 to 3101 Hz. Pristimantis marmoratus is primarily arboreal, exclusively active at dusk, and propably restricted to the pristine rainforests of the Pantepui uplands and highlands, east of the Gran Sabana between ca 600 and 1800 m above sea level. Preliminary molecular analyses recovered Pristimantis marmoratus as sister to an unnamed species from the Eastern Guiana Shield. On grounds of the newly established distributional extent we suggest maintaining the IUCN conservation status as Least Concern.
Following a taxonomic revision of Begonia L. (Begoniaceae, Cucurbitales) from Northeast India based on 332 herbarium specimens, 38 species are confirmed to occur in the region, of which ten are endemic. One new species is described, Begonia koelzii R.Camfield sp. nov., in B. sect. Platycentrum (Klotzsch) A.DC. One species is reduced into synonymy; B. barbata Wall. is now a synonym of B. thomsonii A.DC. Three species, B. difformis (Irmsch.) W.C.Leong, C.I Peng & K.F.Chung, B. labordei H.Lév. and B. handelii Irmsch., are reported new for India, and B. lushaiensis C.E.C.Fisch. is reinstated as an accepted species, having previously been synonymised under B. modestiflora Kurz. A key to the species in the region and preliminary conservation assessments are presented.
Chigger mites of the African continent are reviewed using data acquired from the literature and examination of the collections deposited at the Royal Museum for Central Africa (Tervuren, Belgium) and the Natural History Museum (London, UK). All findings for 443 valid chigger species belonging to 61 genera are reported, along with details on their collection locality and host species. Three new synonyms are proposed: Straelensia Vercammen-Grandjean & Kolebinova, 1968 (= Anasuscuta Brown, 2009 syn. nov.); Herpetacarus (Herpetacarus) Vercammen-Grandjean, 1960 (= Herpetacarus (Lukoschuskaaia) Kolebinova & Vercammen-Grandjean, 1980 syn. nov.); Gahrliepia brennani (Jadin & Vercammen-Grandjean, 1952) (= Gahrliepia traubi Audy, Lawrence & Vercammen-Grandjean, 1961 syn. nov.). A new replacement name is proposed: Microtrombicula squirreli Stekolnikov, 2017 nom. nov. pro Eltonella myonacis heliosciuri Vercammen-Grandjean, 1965 (praeocc. Vercammen-Grandjean, 1965). Ninety new combinations are proposed. Keys to subfamilies, genera and subgenera of African trombiculid larvae and diagnoses of these taxa are given.
Damacornu gen. nov. (type species: D. transversum gen. et sp. nov.), Geotypodon papei sp. nov. and Spinotarsus fortehamatus sp. nov. are described, and Helicochetus dimidiatus (Peters, 1855), H. mutaba Kraus, 1960 and Hoffmanides dissutus (Hoffman, 1963) are recorded from the Udzungwa Mts, Tanzania. A complete overview of the 39 odontopygid species now known from the Udzungwa Mts is given, including notes on endemism, biogeographical relationships and altitudinal distribution patterns.
A group of Amazonian harvestmen is recognized and described as Amazochroma gen. nov. This taxon includes Discocyrtus carvalhoi Mello-Leitão, 1941 (type species), the only species of Discocyrtus previously thought to occur in Amazonia, and Amazochroma pedroi gen. et sp. nov., described here from the Brazilian states of Acre and Rondônia. New records are added for Amazochroma carvalhoi gen. et comb. nov, expanding its distribution from the Brazilian state of Mato Grosso northwards also to Pará and Amazonas in Brazil and additionally French Guiana and Suriname. Diagnostic features of Amazochroma gen. nov. include: trichromatic pattern of legs, dry marks on the dorsal scutum and base of legs and diastema in the row of macrosetae C of the penis ventral plate. A morphological maximum parsimony analysis (1022 scorings; 16 taxa; 64 characters) is performed to test whether Amazochroma gen. nov. is a member of Discocyrtus and if the traditional allocation of Discocyrtus in Pachylinae is defendable. A clade is retrieved containing three groups: Amazochroma carvalhoi gen. et comb. nov, here described as a new subfamily of Gonyleptidae - Roeweriinae subfam. nov. Discocyrtanus Roewer, 1929 and Roeweria Mello-Leitão, 1923 are accordingly here transferred from Pachylinae to Roeweriinae subfam. nov.
The species of the subgenus Conocetus Desbrochers des Loges, 1875 are reviewed and Polydrusus (Conocetus) transjordanus sp. nov. is described. Upon examination of the holotype of Polydrusus bardus Gyllenhal, 1834, it was observed that the species hitherto determined sensu auctorum as P. bardus was a misidentification. The specimen in question was therefore unnamed and is thus newly described as Polydrusus (Conocetus) crinipes sp. nov. Polydrusus femoratus (Stierlin, 1888) is a junior synonym of P. angustus (Lucas, 1854). Polydrusus gracilicornis Kiesenwetter, 1864, P. cylindrithorax (Desbrochers des Loges, 1900) and P. quadraticollis (Desbrochers des Loges, 1902) are proposed as junior synonyms of P. bardus. Polydrusus zurcheri (Schilsky, 1912) is proposed as a junior synonym of P. grandiceps (Desbrochers des Loges, 1875). Polydrusus kahri Kirsch, 1865 is transferred from subgenus Conocetus to Denticonocetus subgen. nov., with P. siculus Desbrochers des Loges, 1872 and P. vodozi Desbrochers des Loges, 1903 both recognized as new junior synonyms of P. kahri. The lectotypes of P. gracilicornis, P. zurcheri, P. marcidus Kiesenwetter, 1864, P. gracilis (Stierlin, 1888), P. rhodiacus (Schilsky, 1912) and P. grandiceps are designated. A key, figures, label data and distribution maps are provided for all species, except for P. longus (Stierlin, 1884), for which no specimens were available for examination, and whose placement in the subgenus Conocetus remains uncertain (thus categorized as incertae sedis). Polydrusus angustus is recorded for the first time for Italy, P. rhodiacus for mainland Turkey and P. festae (Solari, 1925) for Greece.
A new Mexican species of Ochraethes Chevrolat, 1860 (Coleoptera, Cerambycidae, Cerambycinae, Clytini) is described: Ochraethes skillmani Wappes, Santos-Silva and Botero. Plocaederus mirim Martins and Monné, 2002 (Cerambycini) is redescribed and its female is figured for the first time. New geographical records in Plocaederus Dejean, 1835 are also provided.
A taxonomic revision of Panamanian species of the genus Dasymutilla Ashmead (Hymenoptera, Mutillidae) is presented and a key for the six species is given, all recognized from both sexes. Dasymutilla colorado Cambra, Williams and Quintero sp. nov., from central and eastern Panama, is described and illustrated. Sex associations permitted us to make the following five synonymies: D. sleipniri Manley and Pitts, 2007 (male) under D. phya (Cameron, 1895) (female); D. deyrollesi Mickel, 1937 (male) and Sphaerophthama [sic.] temaxensis Cameron, 1895 under Dasymutilla araneoides (Smith, 1862) (female); D. ionothorax Manley and Pitts, 2007 (male) under Dasymutilla spilota Manley and Pitts, 2007 (female); and D. guanacaste Manley and Pitts, 2007 (male) under D. paradoxa (Gerstaecker, 1874) (female). Seasonal flight activity for Dasymutilla from six years of continuous malaise trappings in Barro Colorado Island is presented.
Se registra por primera vez el ácaro rojo de las palmas, Raoiella indica Hirst (Acari: Tenuipalpidae), en Guatemala. Este ácaro invasivo se encontró en los departamentos de Petén e Izabal infestando palma de coco (Cocos nucifera), palma de Navidad (Adonidia merrillii) y palmera robeleni (Phoenix roebelenii).
En este estudio se describen dos nuevas especies de hemípteros del género Aleuropleurocelus (Hemiptera: Aleyrodidae): Aleuropleurocelus mexicanus Carapia y Sánchez sp. nov., encontrada en los estados de Coahuila, México, Puebla, Sonora, y Tlaxcala en hojas de Quercus agrifolia Née y Quercus sp., y Aleuropleurocelus anahuac Carapia y Sánchez sp. nov. encontrada en los estados de México, Morelos y Puebla en el envés de hojas de Quercus. Se proporcionan microfotografías de estructuras morfológicas de puparios y se discute la separación con otras especies ovales de Aleuropleurocelus.
An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synonymized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico and Guatemala, Eupogonius giesberti, is described. The following new combinations are established: Fallaxdesmis unicolor (Buquet, 1857) and Eupogonius piperita (Bates, 1855). Illustrations of A. mannerheimii, Fallaxdesmis unicolor, and the holotypes of A. hirticornis, A. vestita, A. unicolor, A. piperita and Eupogonius giesberti are included.
The Trichoptera of Panama V. Descriptions of new species, new country records, and a synonymy
(2018)
The Río Chiriqui basin is one of 52 major watershed areas, or cuencas, in the Republic of Panama. It occurs in western Panama, discharges into the Pacific Ocean, and includes portions of Volcán Barú on its northern extent. The Río Caldera occupies the northernmost subbasin of this basin. Two of its tributaries, Quebrada Grande and Quebrada Jaramillo, occur in close proximity and on opposite sides, and have different recent geologic histories and current land use patterns. During the course of investigating the caddisfly fauna of these two drainages, three new species of the microcaddisfly genus Neotrichia Morton (Trichoptera: Hydroptilidae) were identified: N. collierorum and N. anzuelo from Quebrada Jaramillo and N. tatianae from Quebrada Grande. These are described and figured herein. We also add one new genus (Rhyacopsyche Mueller) and five new country records (Hydroptila paschia Mosely, Metrichia ancora Bueno-Soria and Holzenthal, Ochrotrichia jolandae BuenoSoria and Holzenthal, Rhyacopsyche obliqua Flint, and Chimarra (Curgia) maritza Flint) for Panama. Finally, we designate Ochrotrichia abrelata Harris and Armitage, 2015 as a junior synonym of Ochrotrichia jolandae Bueno-Soria and Holzenthal, 2008. This synonymy and the newly recorded species and country records increase Panama’s known trichopteran fauna to 350 species, distributed among 15 families and 52 genera.
After publication of Blahnik and Holzenthal (2017), it was noticed that a large portion of the text had been accidentally removed from the "Phylogenetic and evolutionary comments" section during the proofing stage. The beginning of the deleted section completes the sentence on line 6 of page 129, which begins "The species included in the subgenus...". The Insecta Mundi editorial staff apologizes for this oversight. In order to provide context for the deleted excerpt, the entire "Phylogenetic and evolutionary comments" section is reproduced here, with the deleted text reincorporated. Insecta Mundi has also released a revised version of the Blahnik and Holzenthal (2017) manuscript, with this error corrected. However, the revised version is merely for convenience, and not an official peerreviewed article. Anyone wishing to reference the findings of Blahnik and Holzenthal (2017) should cite the original 2017 manuscript or this erratum. The references and figure plates cited in this section have also been reproduced here. ...
