Abstract
Nalepa Reitter, 1887 is a monotypic genus of the tenebrionid tribe Blaptini and is endemic to the Tibetan Plateau. In this study, the genus Nalepa was reviewed using a combination of molecular and morphological datasets. Based on the results, six new species were described: N.acuminata sp. n., N. ovalifolia sp. n., N.polita sp. n., N. quadrata sp. n., N.xinlongensis sp. n., and N.yushuensis sp. n. In addition, the larvae of N. cylindracea Reitter, 1887 and N. quadrata sp. n. were described and associated with related adults using molecular approaches. This study provides valuable molecular and morphological data for phylogenetic studies.
