Remark
. In the original description,
Moore (1878)
did not mention a number of specimens therefore the existence of
syntypes
is possible. In order to stabilize the nomenclature, we designate the specimen labeled as ‘type’ as
lectotype
.
Diagnosis.
Forewing length is
13–14.5 mm
in males and
18–19 mm
in females.
Cyana coccinea coccinea
can be distinguished from other members of the
C. insularis
group (sensu
Lourens 2017
) by its orange and red forewing in males (those are white and red in other species). Externally female of
C. coccinea coccinea
is similar to
C. weerawoothi
Lourens, 2017
(
Figs. 9, 10
) described from
Thailand
, but differs by its slightly larger size and slightly narrower red parts of ante- and postmedial lines. The male genitalia of all species of the
C. insularis
group are very similar.
Cyana coccinea
differs from
C. weerawoothi
(
Fig. 164
) by its longer and distally narrowed subbasal dorsal diverticulum, smaller apical diverticulum, larger cluster of spinules on the lateral diverticulum, and its smaller lateral patch of the ventral diverticulum. The female genitalia of
C. coccinea
differ from those of
C. weerawoothi
(
Fig. 237
) by their sclerotized cervix bursae being shorter and more narrowly rugose, smaller and less dentate rugose sclerotized postero-lateral cluster of corpus bursae, and its lateral band-like signum being broader anteriorly.
Distribution.
The nominate subspecies is Himalayan, known from North-East
India
(
Sikkim
and north of
West Bengal
) (
Hampson 1900
) and
Nepal
(
Kishida 1995
;
1998
, as
coccina
, missp.). The records for
Thailand
,
Vietnam
and
Cambodia
(
Černý & Pinratana 2009
;
Bayarsaikhan & Bae 2016
) belong to
C. weerawoothi
.
