New species of the weevil genus Pseudorchestes (Coleoptera, Curculionidae) from Central Palaearctic

Three new species of the genus Pseudorchestes Bedel are described. Pseudorchestes olgae sp. n. known only from the Dzhanybek Station is similar to P. abdurakhmanovi Korotyaev 1993 from Daghestan and southwestern Kazakhstan but differs in the narrower frons, sparse white scales on the frons and on the underside of the head, longer and narrower antennal club, less strongly curved hind tibiae, and larger size. Pseudorchestes tschernovi sp. n. from the Lower Volga River basin, Kazakhstan, and Kyrgyzstan differs from all known congeners, except for P. convexus sp. n. from Transaltai Gobi (Mongolia), in the strongly reduced wings that are only half as long as the elytra, and from the latter species, in the longer rostrum, paler antennae and legs, broad and apically excised scales on the elytra, and short, ovate antennal club in both sexes lacking dense velvety pubescence in male.
