  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, ...

The first record of Dictis L. Koch, 1872 (Araneae, Scytodidae) in the Caucasus

Abstract

Dictis L. Koch, 1875, is recorded in the Caucasus for the first time. Dictis strandi (Spassky, 1941), comb. nov. is transferred to Dictis from Scytodes Latreille, 1804 based on the examined female and two males raised to maturity from the egg sac. Collecting data and digital photos of live and preserved specimens are provided, along with detailed descriptions of both sexes, diagnostic illustrations, and observations on the natural history of Dictis strandi comb. nov. The endogyne is depicted for the first time.
