The male ninth sternum is widely incised and V–shaped posteriorly, and the distal portion of the male tenth tergum is strongly broadened laterally. Male. Body length 16–23 mm (n= 25); forewing length 28–33 mm, hindwing length 26–30 mm. Head (Fig. 7) yellow, vertex with pair of subquadrate or subtriangular black markings near posterolateral margins; postocular spine almost absent.
