  Erranticosa gen. nov.: a New Genus of Wolf Spiders from East Asia with Notes on its Separation from Lycosa and Hogna (Araneae Lycosidae: Lycosinae) Abstract The taxonomy and systematic position of the Eastern Asian wolf spider Lycosa coelestis L. Koch, 1878 are revised using an integrative approach. Our study highlights distinctive morphological and molecular differences that separate this species from the generotypes of Lycosa Sundevall,1833 and Hogna Simon, 1885, to which L. coelestis was previously assigned. Based on these findings, we establish a new monotypic genus, Erranticosa gen. nov., to accommodate this species, namely E. coelestis comb. nov. We also discuss the results of a preliminary molecular phylogenetic analysis of the subfamily Lycosinae, including Erranticosa gen. nov. Additionally, based on morphological examination of the type material, we reject the synonymy of Lycosa subcoelestis Fox, 1935 with E. coelestis comb. nov., transferring it to Trochosa C.L. Koch, ...

New data on the spider (Arachnida: Aranei) fauna of Mangystau Oblast, Kazakhstan

ABSTRACT

A list of 84 spider species of Mangystau Oblast is provided, with the family Dysderidae and 39 species being recorded from there for the first time; five species are first found in Kazakhstan: viz., Argiope ahngeri Spassky, 1932, Uroctea grossa Roewer, 1960, Oxyopes badhyzicus Mikhailov et Fet, 1986, Evarcha nenilini Rakov, 1997, and Theridion arsia Zamani et Marusik, 2021. Distribution of all species that are new to Kazakhstan and Mangystau Oblast is discussed. Three species are described as new: viz., Eresus mangyshlakensis sp.n. (♂), Lycosa kuryk sp.n. (♀), Xysticus utochkini sp.n. (♂). A new synonymy has been established: Minosia simeonica Levy, 1995, syn.n. = Minosia karakumensis (Spassky, 1939). Based on the results of the present study and earlier published data, the total number of spider species recorded from Mangystau Oblast has increased to 195 species in 26 families.
