Abstract

Queinnectrechus fabbrii, new species of trechine beetle from the Zheduo Shan Mountains (Sichuan, south-western China), is described. Specimens of the new taxon have been sampled on the western slopes of the mountain at 4300-4500 m, in alpine pastures with Rhododendron. The new species is sympatric, but not syntopic, in the same mountain with two other Queinnectrechus species, i.e. Q. zheduoshanus Uéno, 1998 and Q. glacialis Uéno, 1998, both of them living on the eastern slopes, the first at 3250 m, in forest, and the second on moraines at 3870-3920 m, respectively. Morphological and diagnostic features of the new taxon are described and illustrated. Furthermore, a key is given for identification of the closely related species of the genus, known so far from the Gongga Shan massif and its vicinities.
