This paper summarizes current knowledge about West African pholcids. West Africa is here defined as the area south of 17°N and west of 5°E, including mainly the Upper Guinean subregion of the Guineo-Congolian center of endemism. This includes all of Senegal, The Gambia, Guinea Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo and Benin. An annotated list of the 14 genera and 38 species recorded from this area is given, together with distribution maps and an identification key to genera. Five species are newly described: Anansus atewa sp. nov., Artema bunkpurugu sp. nov., Leptopholcus kintampo sp. nov., Spermophora akwamu sp. nov., and S. ziama sp. nov. The female of Quamtana kitahurira is newly described. Additional new records are given for 16 previously described species, including 33 new country records. Distribution patterns of West African pholcids are discussed, as well as possible explanations for relatively low West African pholcid species diversity as compared to Central and East Africa.
Two new alcyonacean-associated species, Hamodactylus paraqabai sp. nov. from Papua New Guinea and the Great Barrier Reef and H. pseudaqabai sp. nov. from Indonesia and Malaysia, are described and illustrated. To evaluate the status of the new species and their relationship within the genus Hamodactylus Holthuis, 1952, we combined morphology and phylogenetic analyses based on the cytochrome c oxidase subunit I (COI) mitochondrial gene. Both new species are closely related, with their mutual genetic divergence reaching 3-4%. They are further most related to Hamodactylus aqabai Bruce & Svoboda, 1983, originally described from the Red Sea. Both new species are distinguished from all other congeners by the presence of multiple teeth distally on the cutting edges of the fingers of the first pereiopods, and, in the case of H. paraqabai sp. nov., by a full reduction of the fixed finger on the second pereiopod chela. In H. pseudaqabai sp. nov. the finger is greatly reduced to a small but distinct stub, and the telson bears only a single pair of dorsal spines, as in H. aqabai. A key for the identification of all six currently known species is proposed.
Two new species from South Africa, Dactylonotus nigricorpus sp. nov. and Dactylonotus tsitsikamma sp. nov., are described and illustrated. D. nigricorpus sp. nov. differs from all other species of the genus in the black body, the smaller size and the shorter antenna. D. tsitsikamma sp. nov. is peculiar in the genus in bearing a flag of long setae on the fifth segment of the fore tarsus. An identification key to 6 Afrotropical species of the genus is provided.
Three new species of pseudoscorpion, Allochthonius lini sp. nov. (Xiaoguoquan Cave) and Selachochthonius yinae sp. nov. (Xiao Cave) from Yunnan Province, Allochthonius xuae sp. nov. (Yelaoda Cave) from Guizhou Province, are described and illustrated. An identification key is provided for all known Chinese representatives of the family Pseudotyrannochthoniidae.
We describe three new species of the genus Coletinia Wygodzinsky, 1980, the most diverse of the family Nicoletiidae (order Zygentoma = Thysanura s. str.) in Europe: C. dalmatica Molero-Baltanás, Fišer, Bach de Roca & Gaju-Ricart sp. nov. from Croatia, C. dextra Molero-Baltanás, Bach de Roca & Gaju-Ricart sp. nov. from Spain and C. serrata Mendes, Molero-Baltanás, Bach de Roca & Gaju-Ricart sp. nov. from Portugal. Coletinia dalmatica sp. nov. seems to be related with C. maggi (Grassi, 1887) and both Iberian species belong to the asymetrica species group. New material of some previously recognized species (C. diania Molero, Bach & Gaju, 2013, C. intermedia Molero, Bach & Gaju, 2013, C. mendesi Wygodzinsky, 1980, C. redetecta Molero, Bach & Gaju, 2013 and C. tinauti Molero-Baltanás, Gaju-Ricart & Bach de Roca, 1997) is reported, enlarging in most cases their geographic distribution, and including some new data on their intraspecific variability. Finally, an updated identification key to all known species of the genus Coletinia is given.
Eight species of Diplopeltoides are described from the Swedish west coast. Diplopeltoides suecicus sp. nov. has the cuticle with longitudinal striation visible only under SEM; cuticular plate underlying the cephalic cuticle around the amphid present; cephalic sensilla 4–6 μm long; amphid an inverted U-shape; wide space between amphidial branches areolated; spicules 27–31 μm long; gubernaculum with caudal apophysis. Diplopeltoides longicaudatus sp. nov. is characterized by a cuticle without longitudinal striation; cuticular plate underlying cephalic cuticle around amphid present; cephalic sensilla 13 μm long; amphid an inverted U-shape; narrow space between amphidial branches not ornamented; spicules unequal in size, 27–31 μm long; gubernaculum absent; midventral precloacal cuticular ridge present. D. grandis sp. nov. is characterized by a cuticle with longitudinal striation; cuticular plate underlying cephalic cuticle around amphid present; cephalic sensilla 18.5 μm long; amphid an inverted U-shape; wide space between amphidial branches punctate. The following taxonomic changes are proposed: Diplopeltoides asetosus (Juario, 1974) comb. nov., Diplopeltoides botulus (Wieser, 1959) comb. nov., Diplopeltoides bulbosus (Vitiello, 1972) comb. nov., Diplopeltoides lucanicus (Boucher & Helléouët, 1977) comb. nov., Diplopeltoides pumilus (Vincx & Gourbault, 1992) comb. nov. and Diplopeltoides striatus (Gerlach, 1956) comb. nov. Diplopeltoides holovachovi Fadeeva & Mordukhovich, 2013 is synonymised with Diplopeltoides pumilus comb. nov. An updated key to the species of Diplopeltoides is provided.
Muscid species of the 'Spilogona contractifrons species-group' (Spilogona alticola (Malloch, 1920), S. arctica (Zetterstedt, 1838), S. contractifrons (Zetterstedt, 1838), S. orthosurstyla Xue & Tian, 1988) and of the 'Spilogona nitidicauda species-group' (S. nitidicauda (Schnabl, 1911), S. hissarensis Hennig, 1959, S. imitatrix (Malloch, 1921), S. platyfrons Sorokina, 2018) are notoriously difficult to distinguish. In this paper, their morphological features are analysed, images of the male head, frons and abdomen of all the species are given, and the male terminalia are figured. The study of extensive material has shown that all the morphologically recognised species in each of these groups are valid species. An identification key is provided for both groups of species. To confirm the morphological differences, genetic differences in the cytochrome oxidase I gene of flies of the 'Spilogona contractifrons speciesgroup' and of the 'Spilogona nitidicauda species-group' were analysed. It is shown that members of both groups of species have not only distinguishing morphological characters but also fixed substitutions in the DNA sequences. Since a low interspecific polymorphism is known in the Muscidae Latreille, 1802, the revealed genetic distances confirm the existence of separate species or subspecies in each of the groups studied.
This paper deals with the taxonomy and faunistics of the genus Diplommatina in Nepal. Altogether 16 species are reported, seven of which are new to science viz. D. abiesiana sp. nov., D. fistulata sp. nov., D. godawariensis sp. nov., D. maipokhariensis sp. nov., D. salgharica sp. nov., D. shivapuriensis sp. nov. and D. syabrubesiensis sp. nov. Information on nine previously reported species is provided: D. exserta Godwin-Austen, 1886, D. folliculus (L. Pfeiffer, 1846), D. miriensis Godwin-Austen, 1917, D. munipurensis Godwin-Austen, 1892, D. oviformis Fulton, 1901, D. pachycheilus Benson, 1857, D. regularis Fulton, 1901, D. silvicola Godwin-Austen, 1886 and D. sperata W.T. Blanford, 1862. Although D. canarica was once reported from Nepal, it is not treated here as it is an endemic of the Western Ghats. A dichotomous identification key for all Nepalese species is presented.
The genus Dasydorylas Skevington, 2001 is recorded from two provinces in Iran (Sistan-o Baluchestan and Kermanshah Provinces). Dasydorylas derafshani sp. nov. and D. zardouei sp. nov. are characterized morphologically by DNA barcoding of the mitochondrial COI gene. Eudorylas antennalis Kapoor, Grewal & Sharma, 1987 is transferred to Dasydorlyas (comb. nov.). An existing identification key to the males of the western Palaearctic species of Dasydorylas is complemented to include the newly described species.
The flower fly genus Afrosyrphus Curran, 1927 (Diptera, Syrphidae) is revised and a new species, Afrosyrphus schmuttereri sp. nov., from Kenya and Uganda is described. Diagnoses, illustrations, DNA barcodes and known distributional data are provided for the two species of this genus, as well as an identification key. A critical review of the published literature is also provided.
