Establishment Of The Genus Ceratopanorpa And Its Taxonomy(Mecoptera: Panorpidae)

Panorpidae, the largest and highly speciose family in Mecoptera, are composed of morethan420described extant species in six genera: Panorpa Linnaeus,1758; LeptopanorpaMcLachlan,1875; Neopanorpa Weele,1909; Sinopanorpa Cai&Hua,2008; FurcatopanorpaMa&Hua,2011; Dicerapanorpa Zhong&Hua,2013. According to the observation of theadult and genitalia with stereoscopic zoom microscope and scanning electron microscope, anew genus Ceratopanorpa gen. nov. is erected with Panorpa emarginata Cheng,1949as itstype species.Ceratopanorpa is recognizable by the following characters:1) posterior process ofabdominal segment3th in male not obvious, tergum6with one anal horn;2)7-8th abdominalsegments elongated and constriction at the base;3) stalk of hypandrium (ninth sternum) inmale short, the paired hypovalves long and slender;4) dorsal valve of aedeagus long andslender, weakly sclerotized; ventral valve short, membranous;5) parameres long and simple,generally bearing hairs at the distal half, dorsal process not obvious;6) female genital platewith axis long; posterior arms of the main plate not so developed, roughly form a broadU-shape; at the base of genital platemostly bear two pairs of basal side plate.Twenty-one species are described in Ceratopanorpa. Two new species are found:Ceratopanorpa liupanshana sp. nov. and Ceratopanorpa peloroprocessus. sp. nov.. Nineteennew combinations are transferred from Panorpa, including: C. emarginata (Cheng,1949), C.obtusa (Cheng,1949), C. nanwutaina (Chou in Chou et al.,1981), C. wangwushana (Huang,Hua&Shen,2004), C. dubia (Chou&Wang in Chou et al.,1981), C. byersi (Li&Hua,2007), C. acutipensis (Hua,1998), C. brevicornis (Hua&Li,2007), C. funiushana (Hua&Chou,1997), C. reni (Chou in Chou et al.,1981), C. centralis (Tjeder,1936), C. kiauti (Zhou,1993), C. bicornifera (Chou&Wang in Chou et al.,1981), C. flavipennis (Carpenter,1938),C. anfracta (Ju&Zhou,2003), C. concolor (Petersen,1915), C. horiensis (Issiki,1929), C.triangulate (Huang&Hua,2005). and C. elagans (Huang&Hua,2005). Two new synonymsare found, P. leei Cheng,1949(syn. of P. obtusa Cheng,1949) and P. alticola Zhou,2000(syn. of P. obtusa Cheng,1949). A key to the species of Ceratopanorpa gen. nov. ispresented. The boundaries among Ceratopanorpa are obscure. Moreover, overlapping distributionand interspecific variation in wings and genitalia result in the species identification to be moredifficult. We used more than180specimens collected from Taibai Mountain to study thevariation of C. obtusa, and have a more clear understanding of the species boundaries.
