  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, ...

Proteomic profile of the venom of three dark-colored Tityus (Scorpiones: Buthidae) from the tropical rainforests of Costa Rica: Proteomics of Tityus spp. from Costa Rica

Abstract

We aimed to elucidate the potential differences in the venom peptide sequences of three Tityus species from Costa Rican rainforests: T. jaimei, T. championi and T. dedoslargos, compared to T. cf. asthenes from Colombia, which could explain the low level of scorpionism in Costa Rica, evidenced by the lack of epidemiological data.
