Statistics: 1 species.
Host Plants: Unknown.
Comments: We have not been able to study a
representative of this genus. Therefore we include in the
diagnosis the pertinent characters from the original description
(Chen, 1939).
Diagnosis: Body very small,
oblong, subparallel-sided, slightly convex from lateral view.
Color shining black, antenna and legs fulvous.
Head fairly deeply inserted in prothorax; frontal
calli absent or rudimentary: interantennal space broad, scarcely
convex, bounded above by impressed line which arched or angulate
in middle; clypeus depressed and truncate in front; anterior edge
of labrum rounded; maxillary palpi not slender, terminal joint
pointed. Antenna short, five apical joints distinctly
thickened.
Prothorax broader than head, nearly twice as broad as
long, anterior angles slightly thickened, subrounded or
subtruncate, not produced; posterior angles widely rounded ...;
base rather thickly margined, nearly straight; surface punctate
often with transverse impressions situated close ... to base and
extending on either side to near lateral margin ... Scutellum
with apex rounded. Elytra slightly broader at base than
prothorax, slightly depressed before middle, somewhat more convex
below; apex narrowed, rounded; punctation arranged in eleven
regular longitudinal rows, including short scutellar and extreme
marginal rows.
Anterior coxal cavities open behind. Prosternum of moderate
breadth, dilated beyond coxae, posterior end nearly truncate.
Mesosternum inclined towards anterior. Legs slender; posterior
femora only feebly incrassate but endoskeletal structure present;
tibiae not channeled at their outer face, each with small spine
at apex; third joint of tarsi bilobed, first joint of posterior
pair as long as following two combined; claw
