Dolbina
Staudinger
Type species:
tancrei Staudinger (Amur to Japan).
The species are smaller than in preceding genera, with rather narrow,
apically produced forewings that have a distinctive pale discal spot and a
series of oblique, slightly curved, crenulate fasciae. The abdomen is
variegated with diamond-shaped markings. In the male genitalia the uncus
is broad, short, apically triangular; the gnathus is apically bifid; the
aedeagus has an apical tooth. The harpe on the valve is large, with a
spine-like ventral process and an irregularly lobed dorsal one.
The larva is typical of the Sphinginae. The pupal tongue case is not free
(Bell & Scott, 1937).
