A new genus of the spider family Corinnidae, Spinirta gen. nov., with nine new species is described from southern China: S. jinyunshanensis sp. nov., S. forcipata sp. nov., S. sparsula sp. nov., S. aurita sp. nov., S. aviforma sp. nov., S. quadrata sp. nov., S. leigongshanensis sp. nov., S. qizimeiensis sp. nov. and S. rugosa sp. nov.. Further, one species is transferred from Allomedmassa Dankittipakul & Singtripop, 2014 to this new genus as Spinirta qiaoliaoensis (Lu & Chen, 2019) comb. nov.. The new genus is a close relative of Allomedmassa, Medmassa Simon, 1887 and Paramedmassa Jin, Zhang & Zhang, 2019, but can be distinguished by the unique spines on the ventral surface of the RTA of the male palp, and the anteriorly situated, large, separated COs or fused into a large atrium of the female epigyne.

New Genus And Species

A new genus and species of fossil hawker dragonfly, Parabaissaeshna ejerslevense gen. et sp. nov. (Aeshninae: Allopetaliini), is described from the Early Eocene Fur Formation (Mo-clay) of the island of Mors, northern Denmark. Its position among traditional “gomphaeschnine” dragonflies is discussed, and it is attributed to the tribe Allopetaliini as close relative to the Cretaceous genus Baissaeshna, documenting the survival of this lineage through the K-Pg mass extinction. The Recent genus Boyeria and the Eocene genus Anglogomphaeschna are also transferred to Allopetaliini.

Abstract Until now, the pre-Miocene fossil record of mustelids in North America has been restricted to specimens attributable to oligobunine taxa and isolated remains tentatively allocated to the genus Plesictis. In the present study, we report on a nearly complete cranium and a referred dentary of a new genus and species of mustelid. The specimens were recovered from the Turtle Cove and Kimberly Members of the John Day Formation, Oregon, USA. These excellently preserved specimens more confidently confirm the presence of mustelids in the Early and Late Oligocene (Early and Late Arikareean) of North America. Like the holotype specimen of ‘Plesictis’ julieni, the new species lacks an alisphenoid canal and a postprotocrista on the M1 (synapomorphies of Mustelidae), but retains a dorsally deep suprameatal fossa (a feature occasionally suggested to be unique to Procyonidae). Phylogenetic analyses, applying parsimony and Bayesian inference to combined molecular (five genes totalling 5490 bp) and morphological data, recover this new species of mustelid as sister-species to ‘Plesictis’ julieni. The results of these analyses reveal that the new genus is a close relative of other species of Plesictis and several taxa traditionally allied with Oligobuninae, thereby rendering Oligobuninae paraphyletic. We further discuss the significance of the relatively small size of this new mustelid as it relates to predictions based on increased aridification of the palaeoclimate and the expansion of open habitats in the Oligocene.

Systematics and biology of the Leopard-spotted Goby, Gobius ephippiatus [Teleostei: Gobiidae], with description of a new genus and notes on the identity of G. macrolepis Kolombatovic

The leopard-spotted goby, Gobius forsteri Corbin 1958, described from the western English Channel, is identified with the Madeiran Gobius ephippiatus Lowe 1839, the latter name becoming a senior subjective synonym for this species. From study of variation, with size of fish, in number of lateral-line sensory papillae in preopercular-mandibular row i, it is concluded that the Aegean Gobius thori De Buen 1928 may also be referred to G. ephippiatus. Examination of the syntypes of G. macrolepis Kolombatovic 1891, from the Adriatic, has shown that this name belongs to a close relative of G. ephippiatus and not to Mediterranean populations of the Atlantic Lesueurigobius friesii (Malm), as recent authors have supposed. A new genus, Thorogobius, is proposed for G. ephippiatus, the type species, and G. macrolepis, and a key provided to these two species, which differ in meristic features, development of pelvic anterior membrane and disc, head coloration, and relative number of sensory papillae. Further systematic data on material studied, synonymies, body proportions, papillae and meristic counts are also given.As the complete list of known occurrences indicates, T. ephippiatus appears to be a warm temperate Mediterranean-Atlantic form which penetrates the eastern Atlantic boreal region around the British Isles at least as far north as the North Channel and eastwards to Lulworth Cove (western English Channel). As an inshore shelf species, T. ephippiatus occurs in or near crevices associated with vertical rock faces, from LWST to 30–40 m. Diet probably consists chiefly of crustaceans and polychaetes. Maximum total length recorded is 129 mm, and greatest age 9 years (determined from otoliths), with sexual maturity by the fifth year of life (age 4 +).

Adult Morphology

Fungivorous gall midges of the subfamilies Lestremiinae, Micromyinae, Winnertziinae and Porricondylinae were largely neglected in previous inventories of the Diptera faunas of the Czech and Slovak Republics. A taxonomic-faunistic study focusing on these subfamilies identified a total of 80 species, of which 49 are new records for the Czech Republic and 33 are new records for Slovakia. Species that have never before been found in central Europe are Aprionus dalarnensis Mamaev, 1998, A. oligodactylus Jaschhof, 2009, A. pigmentalis Mamaev, 1998, Asynapta inflata Spungis, 1988, Camptomyia gigantea Spungis, 1989, Cassidoides fulviventris (Mamaev, 1964), Claspettomyia hamata (Felt, 1907), Dendrepidosis longipennis (Spungis, 1981), Dicerura dispersa Jaschhof, 2013, Divellepidosis lutescens (Spungis, 1981), D. pallescens (Panelius, 1965), D. vulgata Jaschhof, 2013, Ekmanomyia svecica Jaschhof, 2013, Holoneurus ciliatus Kieffer, 1896, Monepidosis pectinatoides Jaschhof, 2013, Neocolpodia gukasiani (Mamaev, 1990), Neurolyga acuminata Jaschhof, 2009, Neurolyga interrupta Jaschhof, 2009, Parepidosis planistylata Jaschhof, 2013, Peromyia bidentata Berest, 1988, Porricondyla errabunda Mamaev, 2001, P. microgona Jaschhof, 2013, P. tetraschistica Mamaev, 1988, Schistoneurus irregularis Mamaev, 1964, Spungisomyia fenestrata Jaschhof, 2013, S. media (Spungis, 1981), Tetraneuromyia lamellata Spungis, 1987, T. lenticularis (Spungis, 1987), and Winnertzia parvispina Jaschhof, 2013. A new genus including a single new species of Porricondylini is described and named Glossostyles perspicua Jaschhof & Sikora gen. et sp. nov. on the basis of specimens collected in the Czech Republic and Sweden. Adult morphology suggests that Glossostyles gen. nov. is a close relative of Claspettomyia Grover, 1964.

Twenty-three species of Pauropoda are reported from Canada. They belong to seven genera in two families, Pauropodidae and Brachypauropodidae. A new genus, Amphipauropus, is proposed for Cauvetauropus rhenanus Huther, a close relative of which has been found in Canada. Six species new to science are described and illustrated: Allopauropus remigatus n. sp., Allopauropus marshalli n. sp., Allopauropus tomlini n. sp., Allopauropus asperosus n. sp., Pauropus mixtus n. sp., and Stylopauropus canadensis n. sp. From a distributional viewpoint, the Canadian pauropods all belong to genera with very wide ranges: 52% of the species are known far beyond North America.

Sharp Point

The last few years have been marked by a series of remarkable developments in microscopy. Perhaps the most amazing of these is the growth of microscopies which use devices where the place of the lens has been taken by probes, which record information about the sample and display it in a spatial from the point of view of the context. From the point of view of the biologist one of the most promising of these microscopies without lenses is the scanned force microscope, aka atomic force microscope.This instrument was invented by Binnig, Quate and Gerber and is a close relative of the scanning tunneling microscope. Today's AFMs consist of a cantilever which bears a sharp point at its end. Often this is a silicon nitride pyramid, but there are many variations, the object of which is to make the tip sharper. A laser beam is directed at the back of the cantilever and is reflected into a split, or quadrant photodiode.
