A new genus with a new species of soft-winged flower beetle, Pectotibialis paghmanensis Tshernyshev gen. et sp. nov. are described from Afghanistan. The new genus can be distinguished from the congeners of the tribe Apalochrini by the dark pectination in the apices of tibiae in both sexes, and the anterior tibiae which are hollowed at distal half, flattened and rounded femora, bituberculate basal parts of head and pronotum, two lamellate metathoracic appendages, tarsal comb above second tarsomere of anterior legs, and serrate antennae in the male. Based on the metathoracic appendages and comb in anterior legs would attribute this new species to the new genus Dromanthomorphus Pic, 1921, but all the other above-mentioned characters define its independent status and the designation of a new genus; Pectotibialis Tshernyshev gen. nov. The external appearance, special male characters and genitalia of the type species of the new genus are illustrated, and a distribution map is provided. A key to the Apalochrus-section of the tribe Apalochrini is provided.
Drepanoistodus basiovalis (Sergeeva, 1963) is a common conodont species in Middle Ordovician strata of Baltica. For many years it has been widely accepted that the species encompasses a wide range of morphological plasticity. Hence, several different morphotypes that significantly deviate from the holotype have nonetheless been included in the broad species concept. In this study, we performed a detailed taxonomical study on 112 predominantly well-preserved specimens (geniculate elements) from the St. Petersburg region of Russia; 37 of these were selected for morphometric analyses together with 21 well-illustrated specimens from the published literature. The results demonstrate that, among the morphotypes that share some characteristics with D. basiovalis sensu lato, at least five species can be readily distinguished. Hence, three new species – Drepanoistodus iommii sp. nov., D. svendi sp. nov. and D. viirae sp. nov. – are here added to the previously known D. basiovalis and D. contractus (Lindström, 1955). In addition, some specimens were left under open nomenclature and assigned to Drepanoistodus aff. basiovalis and D. cf. suberectus (Branson & Mehl, 1933). In order to objectively compare the Drepanoistodus taxa and test the validity of the new species, we performed a Principal Component Analysis combined with non-parametric (PERMANOVA) tests based on 21 morphological characters.
The genus Sibogasyrinx has to date included only four species of rare deep-water Conoidea, each known from few specimens. In shell characters it strongly resembles three distantly-related genera, two of which, Comitas and Leucosyrinx, belong to a different family, the Pseudomelatomidae. A molecular phylogenetic analysis of a large amount of material of Conoidea has revealed the existence of much additional undescribed diversity within Sibogasyrinx from the central Indo-Pacific and temperate Northern Pacific. Based on partial sequences of the mitochondrial cox1 gene and morphological characters of 54 specimens, 10 species hypotheses are proposed, of which six are described as new species: S. subula sp. nov., S. lolae sp. nov., S. maximei sp. nov., S. clausura sp. nov., S. pagodiformis sp. nov. and S. elbakyanae Kantor, Puillandre & Bouchet sp. nov. One of the previously described species was absent in our material. Most of the new species are very similar and are compared to Leucosyrinx spp. Species of Sibogasyrinx are unique among Conoidea on account of the high intrageneric variability in radular morphology. Three distinct radula types are found within Sibogasyrinx, two of which are confined to highly supported subclades.
This is a first inventory of Isopoda Anthuroidea from near-shore marine sites in Sulawesi. The material was collected from reefs, sea-grass beds and mangroves of the Minahasa Peninsula in North Sulawesi. Specimens were washed out from benthos samples collected in shallow water. The new species Hyssura reptans sp. nov., Kupellonura indonesica sp. nov., Kupellonura macaroni sp. nov., Pendanthura bangkaensis sp. nov., Expanathura marcoi sp. nov., and Colanthura gerungi sp. nov. are described. We discovered that in Colanthura the mandible is fused to the cephalothorax, a unique feature among isopods. Expanathura collaris (Kensley, 1979) is described from Bangka Island and several differences between other Indo-Pacific populations are discussed.

Twelve species of the subgenus Vestiplex (Diptera, Tipulidae) were previously known to occur in Tibet (= Xizang), China. Here, six species are described and illustrated as new to science: Tipula (Vestiplex) bucera sp. nov., Tipula (Vestiplex) magatama sp. nov., Tipula (Vestiplex) motuoensis sp. nov., Tipula (Vestiplex) nayogabuensis sp. nov., Tipula (Vestiplex) platyphylla sp. nov. and Tipula (Vestiplex) uncinella sp. nov. The following three species are redescribed: Tipula (Vestiplex) himalayensis Brunetti, 1911, Tipula (Vestiplex) nigroapicalis Brunetti, 1911 and Tipula (Vestiplex) zayulensis Alexander, 1963. A key to the species of Tipula (Vestiplex) from Tibet is presented.
In this paper, four new cave-dwelling species of the subgenus Tachycines (Gymnaeta) from Guangxi, Hunan and Jiangxi are described, i.e., Tachycines (Gymnaeta) quadratus sp. nov., Tachycines (Gymnaeta) shiziensis sp. nov., Tachycines (Gymnaeta) sparsispinus sp. nov. and Tachycines (Gymnaeta) papilious sp. nov. The female of Tachycines (Gymnaeta) liboensis Zhu, Chen & Shi, 2020 is recorded for the first time. Moreover, images illustrating the morphology of the four new and three previously described species are provided.
Serratacosa, a new genus of Lycosidae (Araneae) from the southern slopes of the Eastern Himalayas
(2021)
A new wolf spider genus, Serratacosa gen. nov., is erected based on the type and new species, S. medogensis gen. et sp. nov. and two newly combined species, S. himalayensis (Gravely, 1924) (from Hogna Simon, 1885) and S. multidontata (Qu, Peng & Yin, 2010) (from Pardosa C.L. Koch, 1847). All of them are from the southern slopes of the Eastern Himalayas. Descriptions of the new genera and species, and a redescription of S. multidontata are provided together with digital images, illustrations and a distribution map.
In this paper a new tardigrade species, Macrobiotus azzunae sp. nov., from Tunisia, is described. An integrative taxonomic approach was applied by combining morphological, morphometric and molecular data. In particular, light and scanning electron microscopy observations, and four genetic markers, three nuclear (18S rRNA, 28S rRNA and ITS-2) and one mitochondrial (COI) were used. The analysis showed that M. azzunae sp. nov. belongs to the Macrobiotus hufelandi group and is most similar to Macrobiotus sandrae Bertolani & Rebecchi, 1993. It differs from M. sandrae by a more pronounced constriction of the first macroplacoid (hardly visible in M. sandrae) and for the eggshell shape, with thinner wires of the reticulum and meshes around the processes larger than the inter-process meshes in M. azzunae sp. nov., while all meshes are similar in size in M. sandrae. The species is gonochoristic. With this discovery, there are 33 species of tardigrades identified in Tunisia, all non-marine. This result, compared with nearby Sicily, where more research has been conducted, indicates that there is a considerable potential for identification of new species. Further research will be most informative if multiple habitats are explored and if carried out with an integrated approach as done in this present work.
In this report, we analyse the benthic hydroids collected on the Vema and Valdivia seamounts during a survey conducted in 2015 in the SEAFO Convention Area, focused on mapping and analysing the occurrence and abundance of benthopelagic fish and vulnerable marine ecosystem (VMEs) indicators on selected Southeast Atlantic seamounts. A total of 27 hydroid species were identified, of which 22 belong to Leptothecata and only five to Anthoathecata. Monostaechoides gen. nov. was erected within the family Halopterididae to accommodate Plumularia providentiae Jarvis, 1922, and a new species, Monotheca bergstadi sp. nov., is also described. Campanularia africana is recorded for the first time from the Atlantic Ocean, and the Northeast Atlantic species Amphinema biscayana, Stegopoma giganteum and Clytia gigantea are also recorded from the South Atlantic. Three species were identified to the genus level only, due to the absence of their gonosomes. None of the reported species are endemic, and the hydroid community is clearly dominated by species with a wide geographical distribution in the three major oceans. Only Monotheca bergstadi sp. nov. presently has its distribution restricted to the Vema Seamount and the South African coast.
