Forewing (Figs 15, 48-50) longer than widest part (3.16:1), venations as in Fig. 15; hindwing longer than widest part (2.20:1), venations as in Fig. 16. Spinal formula of hind leg 8-12-10.

Remarks.

This species is similar to Saigona robusta Liang & Song, 2006, but can be distinguished from the latter by its anal tube rounded in dorsal view (oval in robusta ); phallobasal conjunctival processes produced posteriorly (produced dorsally and ventrally, respectively in robusta ); phallobase with apical, ventral, membranous lobe small, semi-oval in ventral view (large, triangular in robusta ).
