Cytotaxonomy and molecular phylogeny of the genus Cerapanorpa Gao, Ma & Hua, 2016 (Mecoptera: Panorpidae)

Abstract The species of the genus Cerapanorpa Gao, Ma & Hua, 2016 (Mecoptera: Panorpidae) are characterized mainly by the presence of a finger-like anal horn on tergum VI of males and are distributed in the Oriental and eastern Palearctic regions. Herein, we investigated the pachytene banding pa...
