NZCZSI); ARUNACHAL PRADESH  : 1 ♂, India, Arunachal Pradesh, Daporijo , 7.V.2016, leg. H.S. Datta (Coll. NZCZSI)  .

Remark. The species was described based on several specimens from two distant localities (Sylhet and Java) ( Walker 1854). To avoid any confusion in the future, here we designate the female specimen deposited in the NHMUK collection and labeled as “Type” as lectotype, and fix the species’ type locality as “Silhet”.

Diagnosis. Forewing length is 22–24 mm in males and 23–25 mm in females. Cyana perornata  can be easily distinguished from other Indian congeners by its large size and the presence of only one black discal spot in both sexes. In the male genitalia, the sclerotized valva apex, the large ampulla directed distally and the long and narrow aedeagus are characteristic. In the female genitalia, the ductus bursae is heavily sclerotized, extremely long and strongly connected to the 7 th abdominal sternite.

Distribution. North East India ( Hampson 1900; Singh et al. 2014), Nepal ( Kishida 1994), Bangladesh ( Walker 1854), China (Yunnan) ( Fang 2000), Thailand ( Černý & Pinratana 2009), Vietnam, Cambodia ( Bayarsaikhan & Bae 2016) and Sundaland ( Holloway 2001; Bucsek 2012).
