As for the genus.
Description.
Body moderately broad,
4.4 mm
long,
1.7 mm
wide; surface punctate.
Eyes well-developed, without interfacetal setae. Antennal insertions dorsally exposed. Subantennal groove absent. Frontoclypeal suture absent; anterior clypeal margin multidentate. Antennomeres 2–4 simple; antennomere 5 moderately serrate; antennomeres 6–10 strongly serrate, about as long as wide. Mandibles with one apical and one subapical teeth. Maxillary palps 4-segmented; apical palpomere seemingly cylindrical, not clearly expanded apically. Labial palps 3-segmented; apical palpomere widened apically.
Mentum
subtriangular, apically slightly emarginate.
Pronotal disc subtrapezoidal, widest at base; surface without transverse groove. Prosternum in front coxae transverse, with paired incomplete ridges; ridges not extending to anterior half of prosternum; deep pits absent; prosternal process with subparallel sides. Procoxal cavities broadly open posteriorly.
Elytra elongate; surface of each elytron with 10 puncture rows; epipleura developed only in anterior third.
Legs slender; tibiae slightly longer than respective femora, with two tibial spurs; tarsomeres 1 and 5 elongate; tarsomeres 3 and 4 with well-developed, bilobed membranous ventral process. Pretarsal claws simple.
Hind wing well-developed. Radial cell elongate, about 4.2 times as long as wide; inner posterobasal angle almost right.
Abdominal ventrites with margins denticulate. Sutures between all ventrites complete and distinct; suture between ventrites 4 and 5 only weakly curved. Ventrite 5 about 1.3 times as long as ventrite 4 (might be affected by distortion).
