Abstract: Three cavernicolous species of the ant-loving beetle subfamily Pselaphinae are
described based on the material collected in the dark zone of limestone caves in
southwestern China. Batraxis liyunchuni sp. nov. and Nipponobythus alienoceps
sp. nov. from Guizhou are the first and third cave-dwelling species of their
respective genus, but they do not exhibit particular troglomorphy compared to
epigean congeners. Zopherobatrus lusciosus sp. nov. from Chongqing, showing
typical morphological adaptation to hypogeal lifestyle, is the second known
representative of this obligate cavernicolous genus. In light of the discovery
of a second species, the generic diagnosis of Zopherobatrus is modified
accordingly.
