Description of two new cave-dwelling Bisetocreagris species(Pseudoscorpiones, Neobisiidae) from China

Abstract

Two new pseudoscorpion species of Bisetocreagris Ćurčić, 1983, B. guangshanensis sp. nov. and B. gracilenta sp. nov., belonging to the family Neobisiidae, are described based on specimens collected in karst caves in Guizhou Province, China. Detailed diagnosis, descriptions, and illustrations are presented.

Cave-dwelling pseudoscorpions of China with descriptions of four new hypogean species of Parobisium (Pseudoscorpiones, Neobisiidae) from Guizhou Province

“…As with most Chinese hypogean pseudoscorpions (Table 1; Schawaller 1995;Mahnert 2003Mahnert , 2009Mahnert and Li 2016;Gao et al 2017;; Gao et al 2018; Feng et al 2019;Li et al 2019), these four new species are currently considered single cave endemics. However, this may be due to limited investigations in the region, rather than actual short-range distributions of these species.…”

“…Biospeleological studies in the South China Karst (SCK) has rapidly accelerated in recent years. Since 2017, 39 new subterranean-adapted species across several taxonomic arthropod groups have been described (Gao et al 2017;Huang et al 2017;Li and Wang 2017;Song et al 2017;Tian et al 2017Tian et al , 2018Deuve and Tian 2018;Li et al 2019a). Overall, at least 382 cave-dwelling arthropod species are now known from this region (Ran and Yang 2015;Tian et al 2016;Li and Wang 2017;Gao et al 2018;Feng et al 2019;Li et al 2019b;Liu and Wynne 2019).…”

“…In the last 25 years, cave-dwelling pseudoscorpions from China, specifically in Guizhou, Yunnan, Guangxi, Sichuan, and Hubei Provinces, and Beijing and Chongqing Municipalities, total at least 29 pseudoscorpion species (Schawaller 1995;Mahnert 2003Mahnert , 2009Mahnert and Li 2016;Gao et al 2017;Gao et al 2018;Feng et al 2019;Li et al 2019; Table 1). Of these, 23 are troglobionts and six are troglophiles (Table 1).…”

Two new species of cave-adapted pseudoscorpions (Pseudoscorpiones, Chthoniidae) from Yunnan, China

“…To date, 33 cave-dwelling pseudoscorpion species, representing three families (Chthoniidae, Neobisiidae, Chernetidae), have been described from China. Among them, eight species are known from Yunnan (Schawaller 1995;Mahnert 2003Mahnert , 2009Mahnert and Li 2016;Gao et al 2017;Li et al 2017;Gao et al 2018;Li et al 2019;Feng et al 2020;Gao et al 2020;Zhang et al 2020).…”

Description of three new Bisetocreagris species (Pseudoscorpiones: Neobisiidae) from Southern China

“…Bisetocreagris live in moist leaf litter, the topsoil layer and caves. At present, the genus Bisetocreagris includes 39 species and subspecies, of which 24 species (13 leaf litter inhabiting and 11 cave-inhabiting species) have been reported from China (Harvey 2013, Mahnert & Li 2016, Guo & Zhang 2017, Gao et al 2017, Li et al 2017.…”
