Etymology. The replacement name is dedicated to G.S. Arora, author of the basic publication on the fauna of the Andaman and Nicobar Islands.

Remark. The taxon tripunctata Reich, 1935 was described under the genus Lyclene . Here we transfer it to the genus Cyana and synonymize with C. detrita (see above). Thus, at present there are two Cyana taxa with the name tripunctata , so tripunctata Rothschild, 1936 becomes a junior secondary homonym of tripunctata Reich, 1935 . Hence, we introduce the replacement name arorai nom. nov. for tripunctata Rothschild, 1936 .

Diagnosis. Forewing length is 12.5–15 mm in males and 17–18 mm in females. Cyana arorai is a polymorphic species, significantly variable in size. Cyana arorai is similar externally to C. carmina ( Figs 13, 14 ), but differs by its arcuate antemedial line (that is oblique in C. carmina ) and larger black discal spots. In females of C. arorai a third, posterior black spot may be developed ( Figs 16, 17 ), what is unusual for the C. insularis group. The female genitalia of C. arorai are very similar to those of C. carmina ( Figs 239 , 240 ), but differ by the more heavily sclerotized cervix bursae having narrower longitudinal folds, and the lateral band-like signum being more weakly sclerotized subanteriorly with its anterior end strongly broadened.

Distribution. Endemic of the Andaman Islands. The records of C. bianca (male) and C. coccinea (female) for the Andaman Islands ( Hampson 1900; Draudt 1914; Arora 1983) belong to C. arorai .
