Diagnosis
. Forewing length is
13.5–14.5 mm
in males.
Barsine dejeani
resembles externally
B. inflexa
and
B. victoria
, but differs clearly by its much larger size and pale red hindwing (whereas in
B. inflexa
and
B. victoria
hindwings are pale ochreous with pinkish suffusion). The male genital capsule of
B. dejeani
is most similar to that of
B. gloriosa
, but can be easily distinguished by its longer uncus, shorter and more curved tegumen (that is straight in
B. gloriosa
), the absence of a dentate plate of manica, broader valva, better developed medial costal process, larger distal costal process directed dorsally (that is directed distally in
B. gloriosa
), broader and more rounded distal membranous lobe of valva, the presence of the large setose basal lobe of sacculus (absent in
B. gloriosa
), and more rounded and less prominent distal saccular process. The aedeagus of
B. dejeani
is shorter and stronger S-like curved proximally than that of
B. gloriosa
. In the vesica structure,
B. dejeani
differs from
B. gloriosa
by its bilobate subbasal diverticulum bearing an elongated cluster of spinules (like in
B. victoria
and
B. kanchenjunga
), dorsal medial diverticulum bearing only granulation, larger ventral medial diverticulum with more robust cornuti, longer distal diverticulum bearing a band-like cluster of small robust cornuti basally, and larger basal plate of vesica ejaculatorius.
The female is unknown.
Distribution
. South West
China
(
Sichuan
).
Etymology.
The species name is dedicated to its collector, R.P. Déjean.
