AMERIZUS (TIRUKA) GAOLIGONGENSIS SP. N. (COLEOPTERA: CARABIDAE): AN ENDOGEAN ADAPTED REPRESENTATIVE OF THE GENUS

Abstract

We describe and illustrate Amerizus (Tiruka) gaoligongensis sp. n. (type locality: cave Wu Shi Shan 1-2-3, near village Kongshuhe, Tengchong County, Yunnan, China). The species possesses a set of real troglomorphic characters, such as depigmentation of tegument, prolongation of the appendages, microphthalmy, roundness of both pronotum and elytra, and brachyptery. These special features, together with three corporal indexes and peculiarities in the structure of the aedeagus, enable a readily distinction of the new species. Otherwise, A. gaoligongensis seems related to species from the queinneci species-group.
