Remark
. In the original description (
Černý & Pinratana 2009
), the species was compared with
C. malayensis
Hampson
only. Its male and female genitalia have no significant differences from those of
C. selangorica
therefore here we consider
C. paeninsulana
to be conspecific with
C. selangorica
. However, this taxon has external differences from the nominate populations of
C. selangorica
and, in addition, some slight differences in the male clasping apparatus. For this reason, we consider the taxon to be a northern subspecies of
C. selangorica
:
C. selangorica paeninsulana
Černý, 2009
,
stat. nov.
Diagnosis.
Forewing length is
15–16 mm
in males and
17–18 mm
in females.
Cyana selangorica paeninsulana
differs externally from the nominate subspecies by its slightly narrower and more reddish transverse lines of forewing. In the male genitalia,
C. s.
paeninsulana
has the slightly smaller uncus and slightly narrower aedeagus vesica than those of the nominate subspecies. The female genitalia of the new subspecies have slightly larger anterior signum bursae than those of the nominate subspecies. Among the Indian
Cyana
species,
C. s.
paeninsulana
is similar externally only to
C. conclusa
, but can be easily distinguished by its smaller size and postmedial line not curved at anal forewing margin. In the male genitalia,
C. s.
paeninsulana
has characteristic features as the presence of small asymmetrical basal processes of sacculus and the very massive distal saccular process being setose subapically. In the female genitalia, the ductus bursae is narrow and membranous, the posterior section of corpus bursae is rugose, the signa are round, and the appendix bursae is small.
