Etymology. The subspecfic epithet is dedicated the Nicobar Islands where the new subspecies is distributed.

Diagnosis. Forewing length is 16 mm in males and 18.5 mm in females. Cyana conclusa nicobara differs externally from the nominate subspecies by its crimson forewing pattern with narrower transverse lines, whereas in C. c. conclusa the transverse lines are much broader and the pattern is orange or red orange. In the male genitalia, C. c. nicobara has the slightly shorter distal section of valva, the slightly longer ampulla and the slightly shorter distal saccular processes. The female genitalia of C. c. nicobara differ from those of C. c. conclusa by the slightly broader ductus bursae and the smaller medial signum bursae.

Distribution. India (the Nicobar Islands) ( Hampson 1914, as selangorica ; Arora 1983, as ‘ C. javanica sumatrensis (Druce) ’.
