Abstract: This paper deals with the phylogenetic systematics of 11 genera of the tribe Blaptini (Coleoptera:Tenebrionidae) from China based on defensive gland structure. We summarized the characteristics of the glands at the generic level according to position, shape, length, width, distance between the two glands and surface fingerprint whorl, and used this information to compile a key to genera. The phylogenetic relationship of the 11 genera has been established using the HENNIG 86 program (version 1-5). The result shows the evolutionary route should be as follows: Blaptogonia > Prosodes> Thaumatoblaps> Blaps> Asidoblaps> Itagonia> Agnaptoria> Gnaptorina> Dila> Neoblaps> Coelocnemodes. All specimens are deposited in the Museum of Hebei University.
