NHMUK)   .

Remarks. 1. Hampson (1900) cited specimens from Khasis as “Type”, while Bizone signa   was described from Sylhet. 2. In the original descriptions of Bizone signa   and Bizone fasciculata, Walker (1854   ; 1856) did not mention a number of specimens, therefore the existence of syntypes is probable. To avoid any confusion with the similar C. adita   , here we designate the specimens of both taxa deposited in the NHMUK collection and labeled as “Type”s as lectotype.

Diagnosis. Forewing length is 17–19 mm in males and 20–21 mm in females. Cyana signa   differs externally from C. adita   by its distal discal spots merged into a dash, and oblique antemedial line. The male genitalia of C. signa   differ from those of C. adita   by their slightly broader uncus, smaller lateral lobes of vinculum, slightly shorter ampulla, shorter distal lobe of subbasal diverticulum, slightly longer ventral lobe of subbasal diverticulum, and smaller spinules of the distal cluster. The female genitalia of C. signa   differ from those of C. adita   by the broader ostium bursae, the longer sclerotized area in the posterior section of corpus bursae, and the broader appendix bursae.

Distribution. North and North East India (Himachal Pradesh, Uttarakhand, Sikkim, Meghalaya, Manipur, Arunachal Pradesh, Manipur) ( Hampson 1900; Singh et al. 2014), Nepal ( Kishida 1995; 1998), North Bangladesh ( Walker 1854), North Myanmar (Kachin State) ( Hampson 1900), China (Tibet, Yunnan) ( Fang 2000) and North Thailand (Chiang Mai Prov.) ( Černý & Pinratana 2009, part). The specimens illustrated by Černý & Pinratana (2009) as C. signa   belong to C. khasiana   , but we found specimens of the true C. signa   in the CKC collection. The record for Guangdong ( Dubatolov et al. 2012) belongs to female of C. adita   .
