Diagnosis. Forewing length is 7.5 mm in male and 10.5 mm in female. Cyana torrida ( Figs 3, 4 ) differs clearly from the related C. suessmuthi ( Figs 5, 6 ) by its brown forewing pattern and diffuse and posteriorly broadened transverse lines, whereas in C. suessmuthi the discal and subbasal spots are black, the transverse lines are red, narrow and sharply defined. The male genitalia of both species are very similar ( Figs 17, 18 ), but in C. torrida the uncus is broader basally, the transtillar processes are larger, the convex costal margin of valva is more strongly arcuate, the cucullus is narrower, the distal saccular process is shorter and broader, the aedeagus is much more broadened distally with much longer dentation of carinal crest, the lateral diverticulum of vesica with a sclerotised area is smaller, and the distal diverticulum is slightly larger compared to those characters of C. suessmuthi . The female genitalia of the two species are also very similar ( Figs 25–28 ), but in C. torrida the apophyses anteriores are shorter, the antrum is slightly broader anteriorly, and the appendix bursae is much narrower than in the related species.

Distribution. West Africa ( Ghana, Equatorial Guinea) ( Holland 1893; Karisch 2013).
