Panorpa issikiana Byers, 1970

( Figs 1–4 )

Diagnosis (according to BYERS 1970). This species can be recognized by the combination of the following characters: in males, 1) gonostyli lacking median process with basal lobe slightly elongated and acute ( Fig. 2 ); 2) parameres bifurcated, with ventral branch slightly shorter than half length of dorsal branch, extending beyond ventral valves of aedeagus, and enlarged subdistally ( Figs 2, 3 ); 3) dorsal branch of parameres crossed posterior to ventral valves of aedeagus ( Figs 2, 3 ); 4) dorsal processes of aedeagus diverged in distal 1/3 and forming median cleft ( Fig. 2 ). The female is unknown.

Comments. This species was described with a single male holotype, collected by Handel-Mazzetti from Yunnan, China without detailed information ( BYERS 1970). The shape of the epandrium (T9, Fig. 1 ) shows no significant differences to that of many species of Panorpa . Despite the unknown female, the lack of median process in male gonostyli, bifurcated parameres, and greatly sclerotized dorsal processes in aedeagus ( Figs 2, 3 ) suggest that this species is closely related to the following 20 new species, although BYERS (1970) did not mention whether the male A7 is stalk-like at base or not.

Distribution. China: Yunnan (no details) ( BYERS 1970).
