Abstract
Abstract
The Stegana (Steganina) shirozui species group is mainly distributed in East Asia. In the present study, the molecular phylogeny of the S. shirozui group was investigated based on mitochondrial (COI and ND2) and nuclear (28S rRNA) markers. The resulting trees support the S. shirozui group as monophyletic and indicate that in this group, species associated with closer affinities show higher structural homogeneity in male genitalia. Molecular species delimitation assess most species limits and recognize four new species in the S. shirozui group from south-west China: S. alianya sp. nov., S. diodonta sp. nov., S. zebromyia sp. nov. and S. zopheria sp. nov. One new synonym was also recognized. Additionally, three typical male genital characters of the S. shirozui group were placed on the molecular phylogenetic framework. The outcome of both divergence-time estimation and ancestral area reconstruction suggests that the S. shirozui group likely originated in south-west China in the Middle Miocene.
