Description.

BL: 3.7-4.6 mm.

Body reddish. Antennal club (Fig. 84) blackish with terminal segment slightly lighter in basal half and distinctly lighter in apical half. Pronotal fasciae variable, with pair of faint dots (Fig. 18) to two pairs of black dots, the apical dots sometimes connected to basal dots by black stripe (Fig. 17). Inner halves of prohypomera blackish. Prosternum, mesoventrite and metaventrite black. Abdominal sternite III widely black on median portion. Trochanters more or less blackish. Femora varied from reddish-brown to blackish and tibia varied from reddish to dark brown.

Frons finely and sparsely punctate, punctures on vertex coarser than those on remaining surface.

Pronotum slightly raised above elytra. Antebasal puncture row impressed, interrupted at middle, with punctures coarse and regular; discal punctation similar to that of vertex, puncture intervals as broad as 1.5 to 3 puncture diameter.

Elytra with disc slightly impressed apically, basal and sutural stria rows impressed; discal punctation similar to that of pronotum except that on apical impression which is very coarse and dense; each elytron with 3 long discal puncture rows consisting of very coarse punctures, 1st row short and more or less indistinct, 2nd and 3rd rows long and distinct, rarely the presence of an additional row between 1st row and sutural stria rows may be recognized; basal stria row with punctures slightly coarser than those forming pronotal antebasal row, sutural stria puncture row relatively fine.

Prohypomera slightly uneven, with few indistinct punctures on posterior portion.

Mesepisterna smooth.

Abdominal tergites with relatively fine and sparse punctures. Sternite III with distinct micropunctures on median portions, remaining sternites on basal half with dense microsculpture consisting of micropunctures.

Legs relatively long, mesotibiae and metatibiae moderately curved.

Male. Metaventrite (Fig. 19) impressed at middle, with long and suberect pubescence. Protibiae (Fig. 85) almost straight with small tubercles along ventral sides. Median lobe of aedeagus (Fig. 82) with sclerotized internal sac (Fig. 83) consisting of two apical sclerotized rods, x-shaped median sclerite and two basal sclerotized rods.

Distribution.

China (Zhejiang, Anhui).

Remarks.

The species is distinctive for its unique coloration.

Etymology.

The Latin adjective “varifasciatum” refers to the variable fasciae of the pronotum.
