Phylogenetic analysis of the tribe Libnetini with establishment of a new genus (Coleoptera, Lycidae)

摘要

Genus-group taxa of Libnetini are revised and valid taxa are redescribed. Microlyropaeus Pic, 1929 formerly classified with Libnetini (Bocakova 2001a) is transferred to the subfamily Leptolycinae. New genus Prolibnetis gen. n. is proposed within Libnetini, and two new Libnetisia species from China are described: Libnetisia yunnanensis sp. n. and L. xunyanbanensis sp. n. Species Libnetisia leei (Kasantsev et Yang 1999) comb. n. is transferred from Libnetis Waterhouse, 1878. In order to understand relationships within the subfamily, data matrix composed of 15 taxa and 31 characters was assembled and included genus-group taxa were cladistically analysed.
