Abstract: A taxonomic review of the tenebrionid genus Psammocryptus Kraatz, 1865 (Coleoptera: Tenebrionidae: Pimeliinae: Tentyriini) is given. Species of this genus are distributed in the south of Russia (Caspian depression), Transcaucasia, Kazakhstan and Central Asia, Afghanistan and Pakistan, occurring in areas with salty soil, often in tugay forests of river basins. Two new species and one new subspecies are described: P. bogatchevi Nabozhenko, Chigray & Bekchanov, sp. nov. (Kazakhstan: Syrdarya basin, Kyzylkum desert; Uzbekistan: Amudarya lower reaches and delta, Syrdarya basin, Kyzylkum desert); P. kompantsevae Nabozhenko & Chigray, sp. nov. (Uzbekistan and Tajikistan: Amudarya, upper river basin); P. bayeri vachshianus Nabozhenko & Chigray, subsp. nov. (Tajikistan: Vakhsh River valley). The nominotypical subspecies P. bayeri bayeri Koch, 1943 occurs in Turkmenistan (Tejen valley and Amudarya valley middle river course) and Tajikistan (a new record for the country: Kafirnigan River valley). Psammocryptus minutus (Tauscher, 1812) is recorded for Armenia for the first time, but the population from Yerevan has become extinct due to urbanization. The following synonymy is restituted: Psammocryptus minutus (Tauscher, 1812) = P. bergi Kuzin 1934, syn. restit.
