Erranticosa gen. nov.: a New Genus of Wolf Spiders from East Asia with Notes on its Separation from Lycosa and Hogna (Araneae Lycosidae: Lycosinae)

  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, ...

Four new species of Linyphiidae spiders (Arachnida: Araneae) from Jiangjin District of Chongqing, China

Abstract

An ongoing survey on spider diversity in Jiangjin District, Chongqing City has the goal of documenting the regional diversity of spiders. In this context, we here describe four new species of the spider family Linyphiidae from Jiangjin District of Chongqing: Gonatium tridentatum sp. nov. (♂♀), Oedothorax simianensis sp. nov. (♂), Wuliphantes dahonghaiensis sp. nov. (♂♀) and Yuelushannus baishaensis sp. nov. (♂). Detailed descriptions, photographs of copulatory organs and somatic features are presented. Additionally, color photos of Ceratinella brevis (Wider, 1834) (♂) and distribution map of all five species are provided.
