Tibetyrus formicarius Yin Lin, gen. et sp. nov., a new myrmecophilous genus and species of the pselaphine tribe Tyrini, is described from southeastern Xizang, China. Three adults were collected in nests of a Formica ant species (Hymenoptera: Formicidae) at an altitude of 3,485 m. Tibetyrus is similar to Megatyrus Hlaváč Nomura in sharing the basally pedunculate maxillary palpi that lack an apical cone on the fourth palpomeres. Nevertheless, it can be readily separated from the latter and all other genera of the tribe by its unique suite of morphological features as well as a highly recognizable habitus.
西藏蚁隐甲，新属新种（Yin Lin），隶属于隐翅虫科蚁隐甲族Tyrini，发现于中国西藏东南部。在海拔3485米处，从一种蚁属（膜翅目：蚁科）蚂蚁的巢穴中采集到3只成虫。西藏蚁隐甲与大蚁隐甲Hlaváč Nomura相似，其下颚须基部具柄，第四节无顶端锥。然而，它凭借独特的形态特征组合以及极易辨认的体型，很容易与后者及该族的所有其他属区分开来。
