Résumé :	Certhia tianquanensis Li, 1995, is characterised as a distinct species and is combined with C. discolor in the superspecies C. [discolor]. This probably relict species occupies an extremely small range, and has so far been found at only four sites in western Sichuan, China. It is characterised by a long tail (like C. discolor), an extremely short bill (similar to C. nipalensis), the patterning on the underside, with white chin and throat and beige chest and abdomen (like C. himalayana), a striking voice (clearly different from C. discolor and all other Certhia species), and a large genetic distance from C. d. discolor in the cytochrome-b gene. Unlike its closest relative C. discolor C. tianquanensis belongs to the Palearctic fauna; it lives in a region of China inhabited by a number of relict species, several of which are closely related to species in the northern taiga zone. C. tianquanensis is not a close relative of C. familiaris, although it was originally described as a subspecies of the latter and they are locally syntopic. The number of species in the genus Certhia thus rises from six to seven. - Chinese summary: www.do-g.de/journals/.
