  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, ...

Androctonus tinzaouatinensis a new scorpion species from In Guezzam Province, Algeria (Scorpiones: Buthidae)

ABSTRACT

A new scorpion species, Androctonus tinzaouatinensis sp. n. is described and illustrated from the hyperarid Saharan regions of the Tin Zaouatine District, In Guezzam Province and Timiaouine District, Bordj Badji Mokhtar Province, southern Algeria. This new species represents the first record of the genus Androctonus from the Timiaouine and Tin Zaouatine areas. It is compared with congeners from Algeria and Niger, notably A. ajjer Ythier, Sadine, Alioua & Lourenço, A. amoreuxi (Audouin), and A. eburneus (Pallary).
