Diagnosis. Forewing length is 11.5– 12 mm in males and 12.5–13.5 mm in females. Morphologically, D. recta is closely similar to D. rectoides but can be easily separated by its ochreous yellow forewing coloration and fuscous irroration on hindwing. The male genitalia of D. recta differ from those of D. rectoides by their distal saccular process less angled subapically and the presence of only two spines on its apex. The female genitalia of D. recta are similar to those of D. angulifera but differ by the narrower antrum, evenly sclerotized posterior section of corpus bursae (that is sclerotized only laterally in D. angulifera ), and longer diverticulum of the appendix bursae.

Distribution. The species is known from North-East India (Arunachal Pradesh), Bhutan and Thailand.
