Etymology
. In ancient Greek mythology, Britomartis is a goddess of mountains and hunting, who was primarily worshipped on the island of Crete.
Diagnosis
. Forewing length is
20–21.5 mm
in males and
25–25.5 mm
in females.
Cyana britomartis
is a closest relative of
C. divakara
, from which it differs by its smaller black discal spots, broader subbasal white strip along the forewing costa, longer subbasal white spot along the anal forewing margin, and larger medial white spot. In addition, male of
C. britomartis
differs from that of
C. divakara
by its distal discal black spots well separated from each other. The male genital capsule of
C. britomartis
is very similar to that of
C. divakara
, but differs by its slightly narrower juxta, narrower valva with less curved costa, longer distal section of valva, and slightly more robust distal saccular process. The vesica of
C. britomartis
differs from that of
C. divakara
by its shorter but much broader dorsal subbasal diverticulum, larger cluster of spinules on the largest medial diverticulum, larger lateral cluster of spinules, and larger distal diverticulum. In the female genitalia,
C. britomartis
differs from
C. divakara
by its less sclerotized posterior section of the corpus bursae, and much smaller appendix bursae.
Distribution
. The new species is known from North East
India
(
Sikkim
,
Arunachal Pradesh
and north of
West Bengal
),
Nepal
(
Kishida 1994
, as
divakara
) and
China
(
Sichuan
and
Yunnan
) (
Fang 1992
;
2000
, as
divakara
).
