Remarks. 1.
Elwes (1890)
described the species based on three
syntypes
, two males and one female. All three specimens are found in the NHMUK collection (
Figs 98–100
). In order to stabilize the nomenclature, here we designate the male specimen labeled as “Type” as
lectotype
.
2.
Notes on the taxonomy of the
C. dohertyi
species-group were published by
Volynkin
et al.
(2017
; 2019).
Diagnosis.
Forewing length is
15–17 mm
in males and
18–19 mm
in females.
Cyana dohertyi
can be easily distinguished from other Indian species of
Cyana
by the combination of features such as amber yellow forewing pattern, three well-developed round black discal spots on forewing of both sexes, and the presence of a discal spot on hindwing (among Indian species the hindwing discal spot is present only in the
C. divakara
—
C. britomartis
species pair). The male genital capsule of
C. dohertyi
is similar to that of
C. sikkimensis
, but in
C. dohertyi
the valva is slightly narrower and the distal saccular process is longer. The vesica configuration of
C. dohertyi
is similar to that of
C. sikkimensis
,
C. divakara
and
C. britomartis
, but in
C. dohertyi
the largest medial diverticulum bears a long semilunar cluster of short spinules ringing it, whereas in
C. sikkimensis
,
C. divakara
and
C. britomartis
medial diverticulum bears one or two broad clusters of spinules. The female genitalia of
C. dohertyi
is most similar to that of
C. sikkimensis
, but differ by the much narrower posterior sclerotized section of the corpus bursae, the larger signum, and the shorter but broader basal sclerotized part of the appendix bursae.
Distribution.
The nominate subspecies is distributed from Eastern Himalaya (North East
India
(
Sikkim
, north of
West Bengal
,
Assam
,
Meghalaya
,
Nagaland
,
Arunachal Pradesh
and
Manipur
) and Central and East
Nepal
(
Kishida 1993
, as
C. sikkimensis
)) to the Chinese province of Yunnan (
Fang 1992
;
2000
). The populations from North
Thailand
(
Chiang Mai Province
) and North
Vietnam
(Fan-si-pan Mts.) belong to the subspecies
C. d. mertsana
Volynkin & Černý, 2019. The record for the Chinese province of Sichuan (
Daniel 1952
) belongs to
C. lada
Volynkin, Černý & Saldaitis, 2019
(Volynkin
et al.
2019). The record for the Chinese province of Shaanxi (
Daniel 1952
) is doubtful and needs confirmation.
