Remark. In the original description (Černý & Pinratana 2009), the species was compared with C. malayensis Hampson only. Its male and female genitalia have no significant differences from those of C. selangorica therefore here we consider C. paeninsulana to be conspecific with C. selangorica. However, this taxon has external differences from the nominate populations of C. selangorica and, in addition, some slight differences in the male clasping apparatus. For this reason, we consider the taxon to be a northern subspecies of C. selangorica: C. selangorica paeninsulana Černý, 2009, stat. nov.

Diagnosis. Forewing length is 15–16 mm in males and 17–18 mm in females. Cyana selangorica paeninsulana differs externally from the nominate subspecies by its slightly narrower and more reddish transverse lines of forewing. In the male genitalia, C. s. paeninsulana has the slightly smaller uncus and slightly narrower aedeagus vesica than those of the nominate subspecies. The female genitalia of the new subspecies have slightly larger anterior signum bursae than those of the nominate subspecies. Among the Indian Cyana species, C. s. paeninsulana is similar externally only to C. conclusa, but can be easily distinguished by its smaller size and postmedial line not curved at anal forewing margin. In the male genitalia, C. s. paeninsulana has characteristic features as the presence of small asymmetrical basal processes of sacculus and the very massive distal saccular process being setose subapically. In the female genitalia, the ductus bursae is narrow and membranous, the posterior section of corpus bursae is rugose, the signa are round, and the appendix bursae is small.

Distribution. North East India (Assam and Mizoram: first record for India), South Myanmar (Tenasserim) (present study) and South Thailand (Provinces of Chumphon, Ranong and Nakhon Si Tammarat) (Černý & Pin- ratana 2009).
