Diagnosis. Forewing length is 18–19 mm in males and 19–20 mm in females. Cyana candida is very similar externally to C. trilobata , but can be distinguished by its pure white thorax and shorter red strip on the basal part of forewing costa. The male genitalia of C. candida differ from those of C. trilobata by the less massive vinculum, the much shorter ampulla and the smaller spinules of the distal cluster. The female genitalia of the two species are similar, but in C. candida the apophyses anteriores are slightly shorter, the sclerotized area of the posterior section of corpus bursae is shorter, and the appendix bursae is smaller.

Distribution. North and North East India (Jammu & Kashmir, Himachal Pradesh, Uttarakhand and Sikkim) ( Hampson 1900; Kishida 1995) and Nepal (present study). The specimens recorded for Nepal by Kishida (1995) belong to C. trilobata .
