Abstract: The monotypic genus Pakistatyrus Hlaváč, 2006 of the tribe Tyrini (Staphylinidae: Pselaphinae) previously contained a single species described based on two museum specimens found in northern Pakistan. Here I describe P. inconspicuus sp. nov. from a high-altitude area of Tibet. This species differs from P. ater Hlaváč, 2006 in reddish-brown coloration of the body, simple male antennae and metatibiae, and a much broader median lobe of the aedeagus. Both known species are probably locally endemic and have limited dispersal abilities, suggested by their greatly reduced elytra and lack of functional wings. A record of a second species from Tibet, which is represented by a female, is given.
