Abstract
Two new scorpionfly species, Panorpa reflexa sp. n. and Panorpa parallela sp. n., are described and illustrated from Yunnan Province, China. Panorpa reflexa can be readily differentiated from its congeners by the 3-shaped parameres in male genitalia. Panorpa parallela is unique for its parallel parameres in male genitalia. The number of Panorpa species is raised to four in Yunnan Province, and to 113 throughout China.
Highlights
Panorpidae are the largest family in Mecoptera, and currently consist of approximately 400 species in six genera worldwide (Hu et al 2015)
Males of many scorpionflies offer nuptial gifts to the female during courtship and copulation, and use the clamp-like notal organ on the third tergum to seize the anterior edge of the wings of the female (Zhong and Hua 2013a)
Measurements of the right wings of 20 males and 20 females of the two new species were made with a vernier calliper, calculated with Microsoft Excel 2010 and are presented as mean ± SD
Summary
Panorpidae are the largest family in Mecoptera, and currently consist of approximately 400 species in six genera worldwide (Hu et al 2015). The new species can be recognized by the following features: 1) dorsum of body with one broad pale longitudinal stripe mesally; 2) head yellowish brown with the ocellar triangle and the postvertex black; 3) wings hyaline with a greatly reduced pterostigmal band; 4) hypandrium greatly shortened, with hypovalves only reaching the basal third of the gonocoxites; and 5) parameres 3-shaped.
