Species in this group are very similar to those in the Panorpa wormaldi group sensu Issiki (1933) from Japan and southern China by their small body sizes (with forewing length usually not exceeding 14.0 mm), the wings held roof-like ( Figs 1B, C, E & D ; 7 ) or more or less horizontal ( Figs 1A, C, F & G ; 15 ) over the abdomen when at rest, male abdomen shorter than wings, and the short and cylindrical male A6–A8. However, they greatly differ from the latter by the structure of the male and female genitalia: in males, 1) hypandrium usually Y-shaped with slender hypovalves ( cf . usually with U-shaped broad hypovalves); 2) ventral valves of aedeagus membranous ( cf . greatly sclerotized); 3) lateral processes of aedeagus short and simple ( cf . greatly elongated); in females, 4) medigynium lacking dorsal plate ( cf . with greatly developed dorsal plate); and 5) medigynium with pair of posterior arms usually shorter than greatly developed main plate ( cf . pair of long posterior arms longer than poorly developed main plate). Distribution. Central and southwestern China ( Fig. 2 ).
