): forewing with
R

and
R

from upper angle of cell and stalked for more than 1/2 length of
R

, M

and M

from same point of lower angle of cell; hindwing with M

and Rs short-stalked, M

and M

connate from lower angle of cell together with CuA

; underside of hindwing in male with a line of dark scales along upper margin of cell and at base of dorsum; abdomen in male with glossy black scales on dorsal surface of segments one to four, with shallow lateral pouches covered by special scales in membrane between segments two and three; in male genitalia, gnathos tapered distally, transtilla elbow-shaped, valva concave at basal 2/5 on ventral margin and aedeagus with a curved, spine-shaped cornutus; in female genitalia, antrum funnel-shaped, ductus bursae partly sclerotized and shorter than corpus bursae, and corpus bursae at least partially encircled internally by a band of long spines.
Ptyobathra
is similar to
Vinicia
Ragonot,
1893
in the abdominal segments 2 and 3 with deeply invaginated tuft of scales laterally. It can be distinguished by the male labial palpi just reaching vertex, the abdomen in male with black scales on the dorsal surface; the presence of the transtilla, the juxta with lateral arms and the aedeagus without fork-like structure in the male genitalia; and the corpus bursae without spines anteriorly in the female genitalia. In
Vinicia
, the labial palpi exceed far beyond vertex, the abdomen in male lacks black scales on the dorsal surface; the transtilla is absent, the juxta does not have lateral arms and the aedeagus has fork-like structure in the male genitalia; and the corpus bursae possesses spines anteriorly in the female genitalia.
