Diagnosis
. Forewing length is
13 mm
in the male
holotype
.
Cyana bianca
(
Fig. 1
) is most similar externally to
C. juliettae
(
Fig. 2
) and
C. carmina
(
Figs 3, 4
), but can be distinguished by the red parts of its ante- and postmedial lines being less broadened posteriorly. In addition, its black outer margin of the antemedial line is stronger curved at costa than that of
C. carmina
. In the male genital capsule (
Fig. 11
), the valva apex is slightly broader than that of
C. juliettae
(
Fig. 14
) and
C. carmina
(
Figs 12, 13
). The vesica shape of
C. bianca
is most similar to that of
C. carmina
, but differs by its smaller dorsal medial diverticulum, narrower dorsal distal diverticulum covered with weaker spinules and granulation, larger apical diverticulum, smaller lateral diverticulum bearing narrower cluster of smaller spinules, and less granulated ventral distal diverticulum bearing smaller patch of spinules. The female is unknown.
Distribution
.
India
(
Walker 1856
). The species‟ distribution needs clarification based on freshly collected materials.
