Diagnosis. Forewing length is 14–16 mm in males and 17–19 in females. Cyana bianca   ( Figs. 1–4 View FIGURES 1–8 ) has no significant external differences from C. indosinica   sp. nov. ( Figs. 5–10 View FIGURES 1–8 View FIGURES 9–16 ) and C. malayana   ( Figs. 11–16 View FIGURES 9–16 ). The male genitalia of C. bianca   ( Figs. 25–27 View FIGURES 25–27 ) are similar to those of C. indosinica   sp. nov. ( Figs. 28–30 View FIGURES 28–30 ) by the weak ampulla, but differ in the triangular lateral lobes of the vinculum (while in C. indosinica   sp. nov. and other species the lobes are more rounded), the much shorter and narrower medial posterior, medial anterior and distal diverticula, and the narrower medial dorsal diverticulum. The female genitalia ( Fig. 37 View FIGURES 37–42 ) differ from those of other related species ( Figs. 38–41 View FIGURES 37–42 , 43, 44 View FIGURES 43–44 ) more clearly than the male genitalia, and are characterized in the shorter ductus bursae, the long, narrow and weakly rugose posterior sclerotized plate of the corpus bursae, the heavily sclerotized medial-lateral sclerotized band (which is broader, shorter and much more weakly sclerotized in C. indosinica   sp. nov. and C. malayana   and is absent in C. quadripartita   ), and the significantly larger anterior signum.

Distribution ( Fig. 45 View FIGURE 45 ). Nepal ( Kishida 1994), N and NE India (Arunachal Pradesh, Himachal Pradesh, Sikkim, Assam, Meghalaya) ( Kirti et al. 2013), Bangladesh. All records of C. bianca   for Indochina (Candèze, 1927; de Joannis, 1928; Černý & Pinratana 2009; Bayarsaikhan & Bae 2016) belong to C. indosinica   sp. nov. and C. malayana   .
