  New data on spiders (Arachnida, Araneae) of Türkiye, with descriptions of four new species Abstract New taxonomic and faunistic data on Turkish spiders are presented. Four species are described as new to science: Cybaeus anatolicus sp. nov . (♀; Konya) [ Cybaeidae ], Dictyna caligaformis sp. nov . (♂♀; Bursa) [ Dictynidae ], Leptonetela ayvaensis sp. nov . (♂♀; Bursa), and L. oylatensis sp. nov . (♂; Bursa) [ Leptonetidae ]. Except for Cybaeus anatolicus sp. nov ., the remaining new species were collected in caves. Additionally, Drassodes robatus Roewer, 1961 [ Gnaphosidae ] is recorded from Türkiye for the first time, and an unusual variation in the shape of the retrolateral tibial apophysis is documented in an unidentified congener. Additional illustrations are provided for Cataleptoneta aydintopcui Demircan, 2020 [ Leptonetidae ] and Pterotricha kochi (O. Pickard-Cambridge, 1872) [ Gnaphosidae ], for which new localities in Türkiye are reported, as well as for ...

A revision of the psammophilic genus Liobuthus Birula, 1898 (Scorpiones: Buthidae), with a description of four new species from Central Asia

Abstract

The rare Central Asian psammophilic scorpion genus, Liobuthus Birula, 1898 (Scorpiones: Buthidae), is revised. Five species are delineated according to results from three species delimitation approaches using mitochondrial DNA. Results are supported by diagnostic morphology, including an assessment of the distinctive neobothriotaxy. The type species, L. kessleri Birula, 1898, is confirmed for Iran (northeast), Turkmenistan and Uzbekistan (south). Four new species are described: L. atamuradovi sp. n. (Turkmenistan),  L. danovi sp. n. (Kazakhstan, northern Turkmenistan, Uzbekistan), L. shukurovi sp. n. (southwestern Tajikistan), and L. vachoni sp. n. (southern Kazakhstan), The unique additive neobothriotaxy (on both pedipalp femur and patella) first discovered by Vachon (1958) is confirmed and analyzed.
