Morphological phylogenetic analyses and taxonomic revision of the Panorpa davidi group (Mecoptera: Panorpidae)

Abstract The Chinese Panorpa species without anal horn are normally assigned to the davidi group. Here, we taxonomically revise P. group, which currently includes 17 known and four new species: gaokaii sp. nov., huayuani uncinata nov. yaoluopingensis shanyangensis Chou & Wang, 1981 sexspinosa zhongnanensis Ran, treated as junior synonyms of Cheng, 1949. We describe for first time male stigmosa Zhou, 2006, females curva Carpenter, 1938, Navás, 1908, difficilis fructa 1949, jinchuana Hua, Sun Li, 2001. A key group is provided. Phylogenetic analyses maximum parsimony likelihood based on 79 morphological characters show that newly defined a well-supported monophyletic sister genus Cerapanorpa Gao, Ma 2016.
