Summary
The first known troglobiotic species belonging to the ground beetle tribe Patrobini is reported from a limestone cave called Lianhua Dong in Pengzhou, a suburb county-level city in northern Chengdu, Sichuan Province, China. Troglopatrobus zhouchaoi n. gen., n. sp., is an eyeless and large-sized patrobine beetle with extremely elongated body (esp. head and elytra) and appendages. Duvalioblemus (Shublemus) liyuani n. subgen., n. sp., a minute anophthalmic trechine species, is also discovered from the same cave. It is the first cave-dwelling species belonging to this genus already known as endogean from Sichuan and Yunnan provinces.
Résumé

La première espèce troglobie connue de Carabiques de la tribu des Patrobini est signalée d’une cavité karstique nommée Lianhua Dong, située dans le canton de Pengzhou, en périphérie nord de Chengdu, province du Sichuan, Chine. Troglopatrobus zhouchaoi n. gen., n. sp., est un Patrobini anophtalme de grande taille, avec des appendices et un corps très allongés, en particulier la tête et les élytres. Duvalioblemus (Shublemus) liyuani n. subgen., n. sp., est une espèce anophtalme de Trechini, de petite taille, qui a été découverte dans la même grotte.
