Results are presented of an odonatological survey of 23 localities in Thala Barivat District of Stung Treng Province, northern Cambodia, on July 26 – August 1, 2016. Most localities were situated in areas of open low deciduous dipterocarp forests on gravel soils, some at hillside areas of tall evergreen dipterocarp forest. The great Mekong River right bank was studied within 7 km downstream of its Nimith (Nimet, Khon Thai, Labak Koun, Khone Pha Pheng) Waterfall. In total, 55 species were found, of which 52 identified to species and three to genus. Two species, Gynacantha saltatrix Martin, 1909 and Macrogomphus matsukii Asahina, 1986, were recorded in Cambodia for the first time. Five obligatory lotic species were found at the Mekong River, namely Dysphaea gloriosa, Prodasineura coerulescens, Burmagomphus asahinai, Nychogomphus duaricus and Onychothemis testacea, including tenerals of P. coerulescens and B. asahinai. Most probably these species breed in the Mekong reach which is enriched with oxygen downstream of the great waterfall cascade.
Drepanosticta kosterini sp. nov. (holotype ♂, from Gunung Penrissen, Kuching Division, Sarawak, Malaysian Borneo, deposited in RMNH) is described from both sexes. It is the sister species of D. actaeon Laidlaw, 1934; a fresh description of the male of D. actaeon and the first description of the female are given, along with discussion of variation in this species. Both D. actaeon and D. kosterini are considered to belong to a species group also including D. rufostigma (Selys, 1886) and a preliminary discussion of variation in this species is given, along with illustrations of both sexes. A neighbour joining COI gene tree for D. actaeon and D. kosterini is presented. The relationships of D. actaeon, D. kosterini and D. rufostigma to other members of the Platystictidae are briefly discussed.
The Odonata fauna of flat marshy areas of the Gulf of Siam coast in Koh Kong Province of Cambodia, containing 55 species, is considered. The published data of 2010- 2013 and new data of 2014 and 2016 on the surroundings of Koh Kong town are compiled and the first data on the area of large swampy Melaleuca forests at Andoung Tuek village are presented as well as some occasional photographic records. Gynacantha bayadera, Lyriothemis mortoni and Pornothemis serrata were for the first time recorded for Cambodia. Mortonagrion falcatum was found unexpectedly abundant at Andoung Tuek.

Odonata checklist from Son Tra Nature Reserve, Da Nang city, central Vietnam
Abstract: A checklist of 44 odonate species (21 Zygoptera and 23 Anisoptera) from Son Tra Nature Reserve, central Vietnam is provided. Idionyx thailandica Hämäläinen, 1985 is recorded for the Vietnamese fauna for the first time, a new Coeliccia sp. is awaiting description in the near future, and the taxonomic status of specimens of the genus Leptogomphus remains unsettled and will have to be solved in the future.
Results are presented of a brief odonatological examination of the Abrau and Taman' Peninsulas at the northwesternmost Caucasian Black Sea coast in Krasnodarskiy Kray, Russia, on July 2026, 2017. Twenty three species have been observed at the former peninsula and five at the latter. The Odonata records at the Abrau Peninsula are summarised, to include 34 species.
The survey is based on specimens held at Museums in Australia, Belgium and Germany. Altogether 487 specimens of 31 species from Timor were examined. These include: a recent collection from TimorLeste of 148 specimens (25 species) at the Australian Museum Sydney, an historic collection from West Timor consisting of 338 specimens (20 species) of the excollection Eugène Le Moult, stored at the Institut Royal des Sciences Naturelles de Belgique in Brussels, and a single specimen from West Timor of the Coll. Ris stored at the Senckenberg Naturmuseum Frankfurt, Germany. The following nine species are reported from Timor for the first time: Agriocnemis pygmaea, Austroallagma sagittiferum, Ischnura heterosticta, Xiphiagrion cyanomelas, Crocothemis servilia, Neurothemis ramburii, Orthetrum pruinosum cf. schneideri, Potamarcha congener and Zyxomma obtusum. The female of Anax georgius is described and illustrated. An illustrated key to the Anax species of the Lesser Sunda Islands is given and specimens from the Lesser Sunda Islands formerly identified as Anax gibbosulus are considered to be Anax panybeus. Some characters of the Orthetrum pruinosum taxa group of species, Tramea stenoloba and female Zyxomma obtusum are discussed. Figures of the male appendages and genital ligulae of Austroallagma sagittiferum, Aciagrion fragile and Xiphiagrion cyanomelas are provided, as well as figures of the male secondary genitalia, appendages and the penis of Trithemis lilacina and the male appendages of Epophthalmia vittigera. A preliminary checklist for Timor including 36 species is given.

Odonata found in mid-summer 2015 and 2016 at the north-westernmost Black Sea Coast of the Caucasus, with the first record of Cordulegaster picta Selys, 1854 in Russian Federation
Abstract: Results are presented of brief odonatological examination of the Black Sea coastal northwesternmost spurs of the Caucasus between Anapa and Gelendzhik (mostly at Kabardinka village), Russia, in late July/early August 2015 and early-mid July 2016. In total, 28 Odonata species were found, including Cordulegaster picta for the first time in Russia. For C. picta and Caliaeschna microstigma, the world’s northernmost records were made. New localities of species rare in this area are reported: one for Coenagrion scitulum and three for Selysiothemis nigra, including their breeding habitat. Numerous migrant individuals of Pantala flavescens were observed in many localities in 2015 but none in 2016. Observations on trophic activity of Aeshna affinis and A. mixta are reported, the former showing predominantly matutinal and vespertinal activity and the latter diurnal activity. Occurrence of the Chalcolestes spp. in the Caucasus is discussed.

Calopteryx virgo feminalis subsp. nov., a long known under the same name but hitherto formally nameless subspecies from the Caucasian Black Sea Coast
Abstract: The populations of Calopteryx virgo of the Black Sea Coast of the Caucasus have females with the distal hindwing part darkened and males with the underside of S10 and appendages whitish, They are known for more than a century and deserve a subspecific status but since the name feminalis Bartenev, 1910 proposed to them is unavailable, a new subspecies is formally erected under the same name, Calopteryx virgo feminalis Kosterin subsp. nov., with the following type locality: Russia, Krasnodarskiy Kray, Gelendzhik Municipality, Kabardinka village, the Doob River lowermost reaches, 44°38'26-53'', 37°55'55''-57'58'' E.
New records of Odonata from Kelantan, Malaysia, with a checklist of species recorded from the state
(2017)
We report here the results from field trips to collect Odonata in the central and northeastern parts of Kelantan state, Peninsular Malaysia. Sixty eight species were collected, and 15 of these are new records for the state. Interesting species collected include Euphaea masoni Selys, 1879 and Leptogomphus tioman Choong, 2016. A checklist of the Odonata recorded from Kelantan with a total 131 confirmed species is given in an appendix.
We report here the results from two field trips to collect Odonata in the Crocker Range National Park in western Sabah, Borneo, Malaysia. Thirtysix species were collected. Telosticta fugispinosa had not been described at the time of collection, nor had the two Devadatta species. There was no published record of Protosticta species cf kinabaluensis before the 2012 expedition, nor of Drepanosticta species cf crenitis.
The results of a short collecting trip to Kedah in the northwest of Peninsular Malaysia, made in September 2016, are reported. 64 species were collected, 13–14 of these are new records for the state and 28–29 are new records for the mainland of Kedah. A checklist of the Odonata recorded from Kedah (including Langkawi Island) is given in an appendix. At least 126 species of Odonata are now known from the state.
A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.
Between 2009 and 2016, a total of 174 Odonata species (Tab. 1) have been recorded in the Dehong Dai and Jingpo Autonomous Prefecture, China. 21 of these species are new records for China, and additional 26 taxa have to be described as new to science. Brief comments on selected species refer to morphological characters, distribution and seasonality.

A checklist of all currently accepted species of Grania Southern, 1913 (Annelida, Clitellata, Enchytraeidae) is presented. The genus is widespread over the world and comprises 81 species described to date. Remarks on their geographical distribution, habitat, synonymies and museum catalogue numbers
are provided.
Dendritic and/or rosetted microborings in calcareous and osteic skeletal substrates have a diverse trace fossil record, spanning most of the Phanerozoic, whereas the ichnodiversity of comparable bioerosion traces produced in modern seas is rather limited. The most prominent occurrences are known from Devonian brachiopods and from Upper Cretaceous belemnite rostra. Ichnotaxonomically, they are comprised within one of the few ichnofamilies established to date, the Dendrinidae Bromley et al., 2007. As an outcome of the present revision of this ichnofamily, the plethora of 84 ichnospecies established within 25 ichnogenera since the erection of the type ichnogenus Dendrina Quenstedt, 1849 was considerably condensed to 22 ichnospecies included in 7 ichnogenera, based on a coherent morphological categorisation and ichnotaxobasis assessment. The suite of ichnogenera now subsumed within the Dendrinidae includes Dendrina Quenstedt, 1849; Clionolithes Clarke, 1908; Calcideletrix Mägdefrau, 1937; Dictyoporus Mägdefrau, 1937; Abeliella Mägdefrau, 1937; Nododendrina Vogel et al., 1987; and Pyrodendrina Tapanila, 2008. New combinations thereby concern Dendrina dendrina (Morris, 1851) comb. nov., Clionolithes pannosus (Solle, 1938) comb. nov., C. alcicornis (Vogel et al., 1987) comb. nov., C. convexus (Hofmann, 1996) comb. nov., Calcideletrix anomala (Mägdefrau, 1937) comb. nov., C. fastigata (Radtke, 1991) comb. nov., Dictyoporus balani (Tavernier et al., 1992) comb. nov., Nododendrina europaea (Fischer, 1875) comb. nov., N. incomposita (Mägdefrau, 1937) comb. nov. and N. paleodendrica (Elias, 1957) comb. nov. Investigation of new material and a reassessment of 63 dendrinid microborings previously addressed in informal nomenclature allowed the establishment of two complementing ichnogenera, Rhopalondendrina igen. nov. and Antodendrina igen. nov., and eight new ichnospecies, comprising Pyrodendrina arctica isp. nov., P. belua isp. nov., P. villosa isp. nov., Rhopalondendrina avis igen. et isp. nov., R. acanthina igen. et isp. nov., R. contra igen. et isp. nov., R. tigris igen. et isp. nov. and Antodendrina ligula igen. et isp. nov. In densely bioeroded calcareous substrates, different dendrinids and other bioerosion traces may be found in direct contact with each other, forming composite trace fossils, but some of these associations appear rather systematic in nature and could be the work of the same tracemaker under different behavioural modes, thus forming compound trace fossils. In these cases, however, the distinction between the two concepts remains largely equivocal. Dendrinid microborings are primarily found in living and dead calcareous skeletal substrates of bivalves, brachiopods, belemnites and corals, with complementing records from six other substrate types. Facing considerable sampling artefacts, evidence for true substrate specificity or symbiotic relationships is inconclusive as yet, whereas there is direct evidence for post-mortem infestation in several cases, such as the diverse dendrinid associations in Upper Cretaceous belemnite guards. Despite a wealth of available interpretations, the actual biological identity of the dendrinids’ tracemakers remains largely speculative. The most convincing evidence has been put forward in support of foraminiferans as the producers of Nododendrina, and excavating micro-sponges producing Clionolithes and some Calcideletrix. Since most of the dendrinids are found in aphotic (palaeo-)environments, these two principal types of organotrophic tracemakers are also potential candidates for the other ichnogenera. With regards to evolutionary patterns through geologic time, strong adaptive radiations are evident from the ichnodiversity of dendrinid ichnospecies in the Early to Mid-Palaeozoic, reflecting the “Ordovician Bioerosion Revolution” (sensu Wilson & Palmer 2006) and the “Mid-Palaeozoic Precursor of the Mesozoic Marine Revolution” (sensu Signor & Brett 1984), respectively, and in the Mesozoic, coinciding with the prominent “Marine Mesozoic Revolution” (sensu Vermeij 1977). This pattern mimics that of
other micro- and macro-bioerosion trace fossils and is interpreted as a reflection of increased predation pressure and consequent infaunalisation. For extinction events, in turn, a differential effect is recorded in that the first four of the “Big Five” mass extinctions appear not to have had any noticeable effect on dendrinid ichnodiversity, whereas the end-Cretaceous mass-extinction resulted in a 77% drop following the Cretaceous peak ichnodiversity of 13 dendrinid ichnospecies.
Improving nomenclatural consistency: a decade of experience in the World Register of Marine Species
(2017)
The World Register of Marine species (WoRMS) has been established for a decade. The early history of the database involved compilation of existing global and regional species registers. This aggregation, combined with changes to data types and the changing needs of WoRMS users, has resulted in an evolution of data-entry consistency over time. With the task of aggregating the accepted species names for all marine species approaching completion, our focus has shifted to improving the consistency and quality of data held while keeping pace with the addition of > 2000 new marine species described annually. This paper defines priorities and longer-term aims that promote standardisation within and interoperability among biodiversity databases, provides editors with further information on how to input nomenclatural data in a standardised way and clarifies for users of WoRMS how and why names are represented as they are. We 1) explain the categories of names included; 2) list standard reasons used to explain why a name is considered ‘unaccepted’ or ‘uncertain’; 3) present and explain the more difficult situations encountered; 4) describe categories of sources and notes linked to a taxon; and 5) recommend how type material, type locality and environmental information should be entered.
Loxosceles Heineken & Lowe, 1832 spiders are infamous for their medical importance, but a taxonomic picture of the genus is still far from complete. In this study, the Chilean species of Loxosceles are described and mapped. The males of Loxosceles surca Gertsch, 1967 and L. coquimbo Gertsch, 1967 are described for the first time. Three new species with narrow distributions are described from central and northern Chile: Loxosceles diaguita sp. nov. from the Antofagasta Region, L. pallalla sp. nov. from Coquimbo and L. vallenar sp. nov. from Atacama. The first two species are remarkable in their morphology and do not fit into any of Gertsch’s species groups, suggesting that Chile still harbours an undiscovered phylogenetic diversity of the genus. New distribution records for Loxosceles laeta (Nicolet, 1849) are provided throughout Chile.
Five species of the terrestrial diatom genus Luticola D.G.Mann were found during a taxonomic survey of two small volcanic islands, Ile Amsterdam and Ile Saint-Paul (Southern Indian Ocean). Apart from the two already known Luticola species L. beyensii Van de Vijver et al. and L. subcrozetensis Van de Vijver et al., two new species are described: L. ivetana Chattová & Van de Vijver sp. nov. and L. vancampiana Chattová & Van de Vijver sp. nov. Finally, one, up to now unknown, Luticola species is briefly discussed and illustrated. Detailed morphological descriptions of these taxa are provided based on both light and scanning electron microscopy observations. Morphological features of the new species are compared to morphologically similar taxa, and notes on their ecology and biogeography are added.
The genus Synaldis Foerster, 1863 is recorded in the Neotropical region for the first time. Five new Neotropical species, S. brasiliense Peris-Felipo, sp. nov., S. fritzi Peris-Felipo, sp. nov., S. longiflagellaris Peris-Felipo, sp. nov., S. magnioculis Peris-Felipo, sp. nov., and S. novateutoniae Peris-Felipo, sp. nov., are described and illustrated. The original combination for Synaldis ulmicola Ashmead, 188
A new species of the sessile deep-sea barnacle, Heteralepas (Crustacea, Cirripedia), Heteralepas gettysburgensis sp. nov., is described. The specimens were collected at a depth of 225 m at the Gettysburg Seamount on the Gorringe Bank, located in the Portuguese Exclusive Economic Zone, approximately 200 km off the southwestern coast of mainland Portugal. Extensive morphological and molecular (COI, 12S and 16S) analyses were carried out to separate the species from its nearest congeners with similar geographic distribution, i.e., Atlantic waters.
Siamopsis gen. nov., described here, belongs to a group of genera with the right valve overlapping the left valve in the subfamily Cypridopsinae Kaufmann, 1900 of the family Cyprididae Baird, 1845. The distinguishing characters of the new genus are in the morphology of its valves and soft parts. The postero-dorsal margin of the internal left valve is plate-like protruded. The morphology of this plate varies in different species, e.g., some species bear a tooth-like tubercle on the plate. The posterior margin of the right valve is recurved inwardly at ca mid-height, resulting in the occurrence of a lobe-like expansion that can clearly be seen in the dorsal and caudal views of the carapace. In addition, the other diagnostic soft part features of the new genus are the cylindrical caudal ramus, the presence of two t-setae on the female A2 penultimate segment, the very elongated terminal segment of the Mx1 palp, the morphology of the two large bristles (tooth bristles) of the Mx1 third endite (one smooth, one serrated) and the absence of d-seta on T1. In the present paper, five new species are described under this new genus: Siamopsis renateae gen. et sp. nov., S. suttajiti gen. et sp. nov., S. conspecta gen. et sp. nov., S. khoratensis gen. et sp. nov. and Siamopsis planitia gen. et sp. nov. A key to the species of Siamopsis gen. nov. is also provided.
Two species of the nematode family Diplopeltidae are described from Skagerrak. The new genus Belgopeltula gen. nov. is proposed for Diplopeltula belgica Vincx & Gourbault, 1992 and is characterised by: amphidial fovea circular in female and double-loop-shaped in male; excretory pore located at the level of cephalic setae bases; oral opening on the dorsal side of the body; pharynx subdivided into strongly muscularised fusiform corpus and weakly muscularised narrow and long postcorpus; female didelphic with antidromously reflexed ovaries; supplements absent. Mudwigglus micramphidium sp. nov. is characterised by: a body of 0.6 mm long; cephalic sensilla 1.5 μm long; amphidial fovea loop-shaped, 8 μm long and 3.5 μm wide; gymnostom without cuticularised ring; tail elongate conoid, with subcylindrical distal part; terminal setae absent; spicules 15 μm long; gubernaculum present; two midventral precloacal setae. It is distinguished from M. macramphidium Leduc, 2013 in having shorter amphidial fovea, shorter spicules and presence of two precloacal setae. Redescription of Diplopeltis cylindricauda Allgén, 1932 is provided based on type material. Diplopeltula minuta Vitiello, 1972 is transferred to the genus Mudwigglus Leduc, 2013. Diplopeltis cylindricauda Allgén, 1932, Diplopeltula laminata Vitiello, 1972 and Diplopeltula cassidaignensis Vitiello, 1972 are transferred to the genus Pseudaraeolaimus Chitwood, 1951.
In 1966, Robert William Hayman, Xavier Misonne and Walter Verheyen published their listing of the Congolese, Rwandan and Burundian bat specimens in the collections in the museums of Tervuren, Brussels, Geneva, London and New York. In the fifty years that have passed since, some major changes have been introduced in the taxonomy of the Chiroptera: new species have been discovered, species have been split off, species have been moved to other genera, and additional material has been collected. We re-evaluated the data presented by Hayman et al., and supplemented this with specimen records found in the literature and in online catalogs. This resulted in 136 species, represented by 20 231 specimens (compared to 113 species and 8567 specimens originally). When available, we also recorded additional information such as locality, sex and age, collector, collection date and preservation type of the voucher specimen. The distribution maps of the Congolese taxa are revised to represent the current taxonomy, and are presented in perspective against the taxon’s Species Distribution Model to assess species distribution on the African continent. Additionally, an updated key to the various taxa is presented.
The species-rich giant pill-millipedes (Sphaerotheriida) often represent a microendemic component of Madagascar’s mega-invertebrate fauna. Of the chirping genus Sphaeromimus de Saussure & Zehntner, 1902, ten species have been described. Here, we describe two new species of Sphaeromimus integratively, combining light microscopy, scanning electron microscopy, DNA barcoding and micro-CT technology for the first time in a taxonomic description of a giant pillmillipede. S. kalambatritra sp. nov. and S. midongy sp. nov. are the first giant pill-millipedes collected and described from the mountainous rainforests of Kalambatritra and Midongy. Both species show island gigantism compared to their congeners. Our analysis of the mitochondrial COI gene shows that the two species are related to one another with a moderate genetic distance (9.4%), while they are more closely related to an undetermined specimen from the forest of Vevembe (6.3% and 8.4%). They stand in a basal position with S. ivohibe Wesener, 2014 and S. musicus (de Saussure & Zehntner, 1897). The four aforementioned species share a high number of stridulation ribs on the male harp. Our micro-CT analysis provides a look into the head of S. kalambatritra sp. nov. and shows that non-destructive CT methods are a useful tool for studying the inner morphology of giant pill-millipedes.
We review the three species currently placed in the genus Xylopertha Guérin-Méneville, 1845, and describe a new species, Xylopertha elegans sp. nov., from Turkey. We propose the following new synonymy: Xylopertha Guérin-Méneville, 1845 (= Paraxylogenes Damoiseau, 1968); Xylopertha reflexicauda (Lesne, 1937) (= Paraxylogenes pistaciae Damoiseau, 1968). We give details of the sexual dimorphism, and summarise information on the distribution and biology of all species. A key to the species of Xylopertha is provided.
A new mesoserphid wasp from the Middle Jurassic of northeastern China (Hymenoptera, Proctotrupoidea)
(2017)
A new genus and species of Mesoserphidae (Hymenoptera), Juraserphus modicus gen. et sp. nov., is described based on a well-preserved fossil specimen from the Middle Jurassic Jiulongshan Formation of northeastern China. It is characterized by the following forewing features: the forking of Rs+M located approximately one-third of the distance between 1m-cu and 2r-rs, both 1cu-a and 2cu-a antefurcal; 1-M more than twice as long as 1m-cu and hind wing with cells r and rm closed. In addition, it has a short ovipositor, only extending slightly beyond the metasomal apex. Its new morphological characters broaden the diversity of Mesoserphidae in the Mesozoic and provide new insights into the evolution and relationships of Mesoserphidae.
Aprionus Kieffer, 1894 is one of the most species-rich genera of the fungivorous subfamily Micromyinae (family Cecidomyiidae, gall midges). Eighteen new species of this genus are described here from different parts of the Palearctic region based on morphological characters of male adults: Aprionus balduri sp. nov. (Norway, Sweden), A. bestlae sp. nov. (Sweden, Czech Republic), A. borri sp. nov. (Sweden), A. fontanus sp. nov. (Germany), A. friggae sp. nov. (Sweden), A. fujisanensis sp. nov. (Japan), A. hugini sp. nov. (Sweden, Germany), A. magnii sp. nov. (Sweden), A. montivagus sp. nov. (Germany, Russia), A. munini sp. nov. (Sweden, Germany, Hungary), A. odini sp. nov. (Sweden), A. ogawaensis sp. nov. (Japan), A. sifae sp. nov. (Sweden), A. sleipniri sp. nov. (Sweden), A. surtri sp. nov. (Sweden), A. thori sp. nov. (Sweden), A. tyri sp. nov. (Sweden), and A. ymiri sp. nov. (Sweden, Finland). These species are classified with the angulatus, halteratus and smirnovi groups, or remain unclassified within the genus Aprionus. The styloideus subgroup of the halteratus group is established for seven species (four described here as new) with generally similar male genitalic morphology. Aprionus paludosus Jaschhof & Mamaev, 1997 is revived from synonymy with A. styloideus Mamaev & Berest, 1990, and both species are redescribed.
