A new species of the genus Cerapanorpa (Mecoptera, Panorpidae) from the eastern Bashan Mountains

Cerapanorpa Gao, Ma & Hua, 2016, an endemic genus of Panorpidae in central China's mountain regions, currently comprises 21 described species. Recently, the short-horned scorpionfly C.brevicornis (Hua & Li, 2007) was confirmed to contain two valid species by phylogeographic and morphological data. Individuals from the highlands of the eastern Bashan Mountains were suggested as a good species, separated from the original short-horned C.brevicornis.

Cerapanorpaalpina sp. nov. was described from the alpine zone of the eastern Bashan Mountains in central China. The new species differs from its congeners by the following combination of characters: male bearing an extra-short anal horn on posterior margin of tergum VI; paramere elongate, extending beyond the median tooth of gonostylus and curved laterally at basal half; female medigynium slightly constricted medially without dorsal basal plate. The species number of Cerapanorpa is raised to 22.
