Diagnosis. Forewing length is 18–20 mm in males and 21–21.5 mm in females. Externally, C. neopuer has no differences from C. puer and differs by the genitalia structures only. In the male genitalia, the vesica structure is diagnostic: in C. neopuer only two small medial diverticula have clusters of spinulose scobination and the third medial diverticulum is membranous, whereas in C. puer all the three small medial diverticula bear clusters of spinulose scobination. In the female genitalia, the signa bursae of C. neopuer are larger than those of C. puer . FIGURES 19–27. Cyana spp.: adults. 19, C. arorai , ♂, India, S Andaman Isl.
