Head: vertex with medial sulcus plus sulcus on inner margin of each eye; frontal carina straight; clypeus rugose, with small elevations. Antenna: slightly compressed laterally; antennomere 1 subglobose, twice length of 2; 2 transverse; 3–4 cylindrical, subequal in length; 5–10 transverse; 11 pointed at apex. Pronotum: lateral margin slightly convergent on basal ½, strongly constricted on apical ¼; basal impression distinct; punctures shallow, indistinct; surface totally covered with microsculpture; with faint medial longitudinal sulcus; pronotal length 1.4 mm (n=1); pronotal width 2.3 mm. Scutellum: trapezoidal, posterior margin rounded. Elytron: with 10 rows of punctures, scutellar row absent; carinae 1 and 2 united apically; lateral margin with small teeth basally, larger ones apically; apical margin with large tooth in exterior apical angle and smaller tooth at end of puncture row 6; elytral length 7.5 mm; elytral width 2.8 mm.
