ABSTRACT. Twelve gnaphosid species have been described by O. Pickard-Cambridge  from Himalaya and Pamir. Of them only two Gnaphosa have been redescribed based on the types. Ten other species: eight species placed in Drassus Walckenaer, 1805 and two in Micaria Westring, 1851 have been never studied since their description. Study of types represented by adults reveals that at least four species placed in Drassus and later in Drassodes Westring, 1851 are misplaced. Two new combinations are suggested: Coreodrassus interlisus (O. Pickard-Cambridge, 1885) comb.n. and Echemus interemptor (O. Pickard-Cambridge, 1885) comb.n. (both ex. Drassodes). Drassodes infletus known only from females may belong to Echemus Simon, 1878. Taxonomic position of D. involutus remains uncertain. Drassodes lapsus (O. Pickard-Cambridge, 1885) syn.n. described based on a subadult female is synonymized with D. invisus, a species described from the same region. Drassodes dispulsoides Schenkel, 1963 syn.n. and D. parauritus Song, Zhu et Zhang, 2004 syn.n. are synonymized with D. dispulsus (O. Pickard-Cambridge, 1885). It was found that Micaria connexa O. Pickard-Cambridge, 1885 syn.n. and M. pallida O. Pickard-Cambridge, 1885 syn.n. are synonyms with M. lenzi Bцsenberg, 1899. Although these names are senior synonyms of M. lenzi, because of the lack of usage of these names [ICZN, 2019: Art. 23.9.1] vs. wide usage of M. lenzi we preserve the junior synonym as the valid name. Type localities of six species described by O. Pickard-Cambridge are indicated incorrectly in the World Spider Catalog and are rectified here. A new combination is suggested for Echemus incinctus Simon, 1907, a species known from Western Africa: Hongkongia incincta (Simon, 1907), comb.n.
