Sacarum nemkovi gen. et sp.n. (Aranei: Nesticidae), from the steppe Cisurals, Russia

Abstract

Europe, E. pallida is a typical indoor dweller [Nentwig et al., 2022]; yet, it was recorded as a troglophile species [Mammola et al., 2018]. N. mogera is represented by introduced populations in Europe and the Urals. In temperate areas of Europe, it is a true synanthropic (=eusynanthropic) species [Esyunin et al., 2019]; naturalized populations of this species are only known from South Europe (Ballarin, pers. comm.) and the Caucasus [Marusik, Guseinov, 2003].At the moment, three nesticid species have been reported from the Urals [Esyunin, Efimik, 1995, 1998Esyunin et al., 2019], of which one, Aituaria pontica (Spassky, 1932), is known from the cis-Ural steppe zone [Esyunin, 2017]. During the past decade numerous materials have been collected from various localities of the steppe zone of Orenburg Area. A new nesticid-like species belonging to an undescribed genus has been found in this material. The aim of the present work is to diagnose and describe these new species and genus.

Integrative taxonomic revision of the genera Nesticella and Howaia in Japan with the description of five new species (Araneae, Nesticidae, Nesticellini)

“…These spiders often show troglophilic preferences and are frequently associated with caves or other dark and humid habitats. The taxonomy and phylogeny of this family has received increasing interest in the last decade by international arachnologists resulting in the publication of numerous new studies (e.g., Liu and Li 2013 ; Ballarin and Li 2015 , 2018 ; Grall and Jäger 2016 ; Lin et al 2016 ; Pavlek and Ribera 2017 ; Ribera 2018 ; Ballarin 2020 ; Suzuki and Ballarin 2020 ; Esyunin and Efimik 2022 ; Fomichev et al 2022 ; Ramírez et al 2022 ; Zigler and Milne 2022 ; Hedin and Milne 2023 ; Ribera and Dimitrov 2023 ; Sherwood et al 2023 ). Such efforts have allowed the description of several new taxa and a progressive revision and redefinition of the family.…”
