The genus Elmomorphus Sharp, 1888 is redescribed based on morphological characters. Elmomorphus bryanti Hinton, 1935, E. montanus (Grouvelle, 1913), E. prosternalis Hinton, 1935, and E. striatellus Delève, 1968 are redescribed based on type material. Elmomorphus nepalensis Satô, 1981 is redescribed based on material collected in the vicinity of the type locality. Eighteen species of Elmomorphus were known so far world-wide, and only five species have been recorded from the study area (India, Nepal, Bhutan, Myanmar, China, Thailand, Laos, Cambodia, and Vietnam). In the present revision, 45 new species are described: E. auratus sp. nov. (China), E. auripilosus sp. nov. (Vietnam), E. bispinosus sp. nov. (China), E. calvus sp. nov.

New taxa and new records of Winnertziinae and Porricondylinae (Diptera: Cecidomyiidae) from Germany
(2024)
Winnertziinae and Porricondylinae are two subfamilies of mycophagous Cecidomyiidae (gall midges). An earlier census in 2021 found the German fauna of both groups to comprise 53 species and 28 genera – only a small proportion of the nearly 400 species and 75 genera known from all of Europe. A 24-month inventory in 2021‒2023, whose most significant taxonomic and faunistic outcomes are presented here, yielded evidence of an additional 142 species and 24 genera present in Germany, more precisely 41 species and three genera of Winnertziinae, and 101 species and 21 genera of Porricondylinae. Included in these numbers are 30 new species (six Winnertziinae, 24 Porricondylinae) and one new genus (of Porricondylinae) described and named here. The number of potentially new species discovered during the project is considerably larger (85+), but the too poor condition of the specimens and various other circumstances do not permit their taxonomic description at this stage. New taxa named in the present paper are Johnsonomyia szadziewskii sp. nov., Rhipidoxylomyia bilobata sp. nov., Winnertzia haushoferorum sp. nov., Winnertzia incrassata sp. nov., Winnertzia macrodens sp. nov., Winnertzia subdentata sp. nov., all Winnertziinae, Asynapta doczkali sp. nov., Asynapta falcata sp. nov., Bryocrypta longissima sp. nov., Camptomyia serrata sp. nov., Cassidoides rainensis sp. nov., Cassidoides riparius sp. nov., Claspettomyia gracilostylus sp. nov., Claspettomyia parvidentata sp. nov., Divellepidosis bavarica sp. nov., Lamellepidosis luderbuschensis sp. nov., Neurepidosis hartschimmelhofensis sp. nov., Neurepidosis simplex sp. nov., Parepidosis lobata sp. nov., Porricondyla acutistylata sp. nov., Porricondyla insolita sp. nov., Porricondyla oblonga sp. nov., Porricondyla ornata sp. nov., Porricondyla pilosoides sp. nov., Porricondyla plana sp. nov., Porricondyla pumila sp. nov., Schistoneurus paraimpressus sp. nov., Schistoneurus subimpressus sp. nov., Spungisomyia germanica sp. nov., Wohllebenia gen. nov., and Wohllebenia hybrida gen. et sp. nov., all Porricondylinae. Taxonomic descriptions are based on both the morphology of males and, if available, CO1 (DNA barcode) sequences, using specimens collected by Malaise traps in Bavaria and Baden-Württemberg, the two southernmost federal states of Germany. Released here are 150 BINs new to BOLD as well as 145 species names for previously unidentified BINs in BOLD. Redescriptions of male morphology are provided for Camptomyia heterobia Mamaev, 1961, Claspettomyia carpatica Mamaev, 1998, Dicerura scirpicola Kieffer, 1898, and Winnertzia betulicola Mamaev, 1963. The state of knowledge of Germany’s fauna of mycophagous gall midges is discussed.
Twelve species of Platypalpus Macquart are described as new to science from different regions in Morocco: P. atlasensis sp. nov., P. brevicornoides sp. nov., P. ebejeri sp. nov., P. fatnae sp. nov., P. pauli sp. nov., P. imlilensis sp. nov., P. miroslavi sp. nov., P. moroccensis sp. nov., P. nigritellus sp. nov., P. rifensis sp. nov., P. shamshevi sp. nov. and P. taninensis sp. nov. Platypalpus albocapillatus Fallén, 1815 and P. boreoalpinus Frey, 1943 are recorded here for the first time from the whole of North Africa, with the first report of P. verbekei Grootaert & Chvála, 1992 from Morocco. Some species newly recorded from new biogeographical areas within the country are also reported here. Descriptions and illustrations of new species are provided, as well as distributions of all species recorded from Morocco.
Due to the fragility of the ophiuroid (brittle star) skeleton, the bulk of the group’s fossil record consists of dissociated ossicles preserved as microfossils. In spite of their great potential as basis for taxonomic and phylogenetic studies, however, ophiuroid ossicles from the Paleozoic have received very little attention so far. Here, we provide an exhaustive taxonomic assessment of such fossils retrieved from sieving residues from the Silurian of Gotland, Sweden. This material was used in a previous study to describe two key taxa that allowed constraining the origin of the extant ophiuroid clade. The remaining taxa belonging to that same lineage are described in the present paper. The evidence at hand suggests that the stem of the extant ophiuroid clade was formed by two genera, Ophiopetagno and Ophiolofsson gen. nov., including six and five species, respectively, and spanning at least the upper Llandovery through upper Ludlow. We conclude that Ophiopetagno and Ophiolofsson represent sister genera that coexisted through most of the Silurian in the shallow tropical seas of Gotland. They underwent repeated body size reductions in correlation with environmental perturbations, with Ophiopetagno paicei eventually giving rise to Muldaster haakei; the first member of the living Ophiuroidea. Herein, we also introduce two new clades, Ankhurida clade nov. and Ophiovalida clade nov., and the following eight new species: Ophiolofsson joelmciveri gen. et sp. nov., O. obituary gen. et sp. nov., O. immolation gen. et sp. nov., O. archspire gen. et sp. nov., O. hendersonorum gen. et sp. nov., Ophiopetagno bonzo sp. nov., O. kansas sp. nov., O. doro sp. nov.; and two probably new species in open nomenclature: Ophiopetagno sp. 1, and Ophiopetagno sp. 2.
In this study, we describe two new species of Mesobiotus based on morphological data collected through light and scanning electron microscopy. Descriptions include DNA sequences of four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). Mesobiotus efa sp. nov. was discovered in North-West Russia and belongs to the group of species with smooth cuticle, harmsworthi-type OCA, typical Mesobiotus claws IV with unindented lunules, and egg chorion with reticulated processes in form of ‘sharp wide cones’ or ‘cones with long slender endings’, egg process bases with well-developed crone of dark thickenings without finger-like projections, and egg shell surface between the processes with ridges without reticulation, areolation or semi-areolation. It can be distinguished from all know species of this group by a unique combination of morphological and morphometric characters. Mesobiotus vulpinus sp. nov. was found in the Russian Far East, and is similar to Mesobiotus mauccii by having an egg chorion with polygonal relief. The new species can be distinguished from M. mauccii by having a narrower buccal tube, by details of oral cavity armature, and by longer egg chorion processes. Furthermore, we provide results of the phylogenetic analyses of the genus Mesobiotus conducted in this study.

The genus Tekellina Levi, 1957 is currently composed of ten species, six of which are Neotropical. They are small-sized spiders (0.9 to 1.5 mm), with a wide distribution, with a great diversity in the Neotropical Region and well represented in Brazil. In this article, males and females of the species Tekellina bella Marques & Buckup, 1993 and T. crica Marques & Buckup, 1993 are redescribed and illustrated. The female of Tekellina minor Marques & Buckup, 1993 is described and illustrated for the first time. New records are included for Neotropical species. Tekellina guaiba Marques & Buckup, 1993 is synonymized with T. pretiosa Marques & Buckup, 1993. Three new species are described for Brazil: Tekellina picurrucha Rodrigues & Estol sp. nov. (São Paulo, Paraná and Rio Grande do Sul), Tekellina miuda Rodrigues & Estol sp. nov. (São Paulo and Paraná) and Tekellina miudinha Rodrigues & Estol sp. nov. (São Paulo). Distribution maps with new records and an identification key of the Neotropical species are also presented.
