Abstract
Two new genera and three new species of cave-adapted ground beetles belonging to the tribe Trechini are established and described: Wulongiusqilingergen. nov. and sp. nov. from limestone cave Qiankou Dong (Chongqing: Wulong), Qianotrechuscongcongaesp. nov. from cave Shigao Dong (Chongqing: Nanchuan), and Qianlongiuszhouigen. nov. and sp. nov. from cave Qianlong Dong (Guizhou: Songtao). Wulongiusqilingersp. nov. is a small aphaenopsian beetle with a thin and elongated body, while Qianlongiuszhouisp. nov. is a semi-aphaenopsian with a stout body. Both new genera are not closely related to any genus of Trechini occurring in the South China Karst, and so their systematic positions remain unclear.
Highlights
The scientific discoveries made in recent years have revealed that the Wuling Mountains harbour a very rich fauna of cavernicolous trechine beetles which is composed of over 30 species in 13 genera (Tian et al 2021)
In April 2021, we conducted a biological survey in three limestone caves in the eastern part of the Wuling Mountains in Chongqing Shi and Guizhou Province (Fig. 1)
Thanks to the assistance of several cavers from the Qilinger Cave Exploration Team (Nanning) and Chongqing Cave Exploration Team (Chongqing), we could successfully survey in cave Qiankou Dong, an upper cave of the Furong Dong system in Tianxing Karst, Wulong
Summary
The scientific discoveries made in recent years have revealed that the Wuling Mountains harbour a very rich fauna of cavernicolous trechine beetles which is composed of over 30 species in 13 genera (Tian et al 2021).
