Preimaginal stages Gnaptor spinimanus (Pallas, 1781) (Coleoptera: Tenebrionidae: Blaptini)
Larvae of the first and the second stages and a pupa of Gnaptor spinimanus (Pallas, 1781) are described and illustrated for the first time. The first stage larva is described for the first time for the tribe Blaptini. This work substantially expands an information about morphology of larvae of the tribe Blaptini and taxonomic significance of characters of tenebrionid larvae and pupae. Some data on ecology and behavior of larvae of the species are given. Larvae of Gnaptor Brullé, 1832 are phyto- and saprophagans and they store vegetative parts of plants in special chambers in the soil.
