Remark. Specimens from eastern Madagascar differ slightly from the topotypical ones of central Madagascar by their somewhat narrower forewing, darker coloration and slightly larger black dots on the forewing. As their genitalia display no noticeable differences, the taxonomic value of the differences expressed in external morphology between the two populations can only be clarified by molecular studies.

Diagnosis. The forewing length is 10–12 mm in males and 11–13 mm in females. Cyana rejecta viettei ssp. n. differs externally from the nominate subspecies by the smaller black dots of the forewing. In the male genitalia of ssp. viettei , the aedeagus is considerably broader, more robust than that of C. rejecta rejecta , the spines in the proximal lobe of the subbasal diverticulum are shorter, and the 1 st medial diverticulum is smaller. The female genitalia of the new subspecies differ conspicuously from those of C. rejecta rejecta by the somewhat longer and narrower ductus bursae and the absence of a band-like scobinated area in the medial section of the corpus bursae.

Distribution. Central and eastern Madagascar.

Etymology. The new subspecies is named after Pierre Viette, renowned expert of Madagascan Lepidoptera and the collector of the holotype.
