Yemen is provided for the first time. The following genera are recorded in the southern Arabian Peninsula for the first time: tribe Doryctini – Hemispathius Belokobylskij & Quicke, 2000 and Doryctes Haliday, 1836; tribe Spathiini – Parana Nixon, 1941 and Spathius Nees, 1819; tribe Hecabolini – Hemidoryctes Belokobylskij, 1992 and Parallorhogas Marsh, 1993; tribe Heterospilini – Heterospilus Haliday 1936; tribe Rhaconotini – Platyspathius Viereck, 1911 and Rhaconotinus Hedqvist, 1965.

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.
Seven new species of the giant pill-millipede genus Zoosphaerium Pocock, 1895 are described from Madagascar: Z. nigrum sp. nov., Z. silens sp. nov., Z. ambatovaky sp. nov., Z. beanka sp. nov., Z. voahangy sp. nov., Z. masoala sp. nov. and Z. spinopiligerum sp. nov. All species are described based on drawings and scanning electron microscopy, while genetic barcoding of the COI gene was successful for six of the seven new species. Additional COI barcode information is provided for the first time for Z. album Wesener, 2009 and Z. libidinosum (de Saussure & Zehntner, 1897). Zoosphaerium nigrum sp. nov. and Z. silens sp. nov. belong to the Z. libidinosum species-group, Z. ambatovaky sp. nov. to the Z. coquerelianum species-group, Z. beanka sp. nov., Z. voahangy sp. nov. and Z. masoala sp. nov. to the Z. platylabum species-group and Z. spinopiligerum sp. nov. to the Z. piligerum species-group. Updated identification keys are provided for each species-group. Two western dry forest species, Z. silens sp. nov. and Z. voahangy sp. nov. are recorded from two localities, while the other five species are currently only known from their type localities. Of special conservation concern might be Z. ambatovaky sp. nov. from the lowland rainforest fragment of Ambatovaky, a nowadays isolated lowland rainforest, rapidly shrinking due to slash and burn agriculture. In addition to the new species, new locality data is provided for 11 species and numerous unidentifiable species of Zoosphaerium: Z. neptunus (Butler, 1872), Z. platylabum (de Saussure & Zehntner, 1902) and Z. piligerum (de Saussure & Zehntner, 1897) from the central eastern montane forests, as well as Z. ambrense Wesener, 2009, Z. aureum Wesener, 2009, Z. libidinosum, Z. corystoides Wesener, 2009, Z. discolor Wesener, 2009, Z. smaragdinum Wesener, 2009, Z. villosum Wesener & Sierwald, 2005 and Microsphaerotherium anjozorobe Wesener, 2009.
Three new species of herb gall wasps (Cynipidae: Aulacideini and Phanacidini) are described from Turkey. Aulacidea turguti sp. nov. induces galls on Hieracium patentissimum Freyn & Sint. ex Freyn, 1895 (Asteraceae) and was collected in Gümüşhane province, Phanacis ciceki sp. nov. and Phanacis urhani sp. nov. were collected in Gümüşhane and Ordu Provinces, the former inducing galls on Picris sp. and the latter on Cirsium vulgare (Savi) Ten., 1835–36 (Asteraceae). SEM images, gall photos, distribution, biology, and diagnostic morphological characteristics of the three new species are provided.
Handaoia Seyrig, 1952 is a small genus of Phygadeuontinae currently represented by eleven described species from Madagascar, Tanzania and Europe, and can be recognized by the combination of the distally expanded and ventrally flattened antennal flagellum, complete posterior transverse carina of the mesosternum, isolated ‘pit’ (episternal scrobe) in the mesopleuron, and a single bulla in fore wing vein 2m-cu. Most species have a distinctive combined area basalis and area superomedia on the propodeum. The following six new species from Central and South America are described and illustrated: H. cuscoensis Bordera sp. nov. from Peru, H. fritzi sp. nov. from Brazil, H. mercedensis Bordera sp. nov. from Peru, H. plaumanni sp. nov. from Brazil, H. ruizcancinoi Bordera sp. nov. from Mexico, and H. urceus sp. nov. from Brazil. A key to the New World species is provided.
The Acanthocinini genus Alcathousiella Monné, 2005 (Coleoptera, Cerambycidae, Lamiinae) is revised with both the genus and the type species, Alcathousiella polyrhaphoides (White, 1855) redescribed. New country records for the species, greatly expanding its known distribution in South America, are also presented. Lastly, Alcathousiella giesberti sp. nov., from Nicaragua, Costa Rica and Panama is described and illustrated.
