TAXONOMY

Dahira jitkae Haxaire & Melichar, 2007, European Entomologist 1(1): 20. Type locality: China, Sichuan, 10Km NW Miansi, 31°27'N 103°23'E, 1300m.


ADULT DESCRIPTION AND VARIATION

Wingspan: 50mm. Visually, very similar to the related species Dahira niphaphylla, but with markedly different male genitalia. In Dahira jitkae these are characterized by the very strongly curved apical process of the aedeagus, with only a pair of small apical teeth. In Dahira niphaphylla and Dahira haxairei the apical process is spatulate and bordered by a row of fine teeth (Haxaire, Melichar & Manjunatha, 2021).
