Two New Species of the Genus Laena Dejean, 1821 (Coleoptera, Tenebrionidae: Laenini) from Jiangsu in China

Resumo

Two new species of the genus Laena Dejean, 1821 belonging to the tribe Laenini, subfamily Lagri inae are described from Jiangsu Province, China: Laena oblonga Wei et Ren, sp. n. and Laena medvedevi Wei et Ren, sp. n. The former was collected under dead leaves of bamboo and differs from all congeners in mesofemora and metafemora with a pair of small teeth; apicale of aedeagus trapezoidal; body distinctly slender. The latter is similar to L. cooteri Schawaller, 2008 and L. hlavaci Schawaller, 2008, but differs from them in the toothed pro- and mesofemora and unarmed metafemora; meso- and metatibiae finely hooked at inner apex. A key to the known Laena species from Jiangsu and adjacent regions is given.
