Diagnostic description

Length

8-11 mm

Colour

Dorsum various shades of green or brown, with red or dark red clypeus, legs and pygidium, and spots and flecks of white or creamy-white dense microtrichiae; pattern of microtrichial patches variable, but at least as follows: pronotal lateral margins (at least partly), several spots on elytron, which may be joined, most of pygidium; mesoventrite process brown, green or red; setae pale, thick and slightly curled; upper surface dull.

Head

Clypeal margin shallowly notched, internal angle 120-145 degrees; densely and strongly punctured and entirely setose (often worn off clypeus); antennal club as long as or slightly shorter than remaining segments.

Pronotum

Lateral margins almost parallel in basal half; strongly but sparsely punctured, with short pale setae; most punctures C-shaped; basal margin shallowly emarginate at junction with scutellum.

Scutellum

Elongate-triangular, with blunt rounded apex; glabrous and impunctate or with scattered setose C-shaped punctures.

Elytra

Almost evenly covered with large, mostly C-shaped punctures, generally seriate on disc and often forming linear grooves near suture; short curved setae present throughout, or often absent from disc; scutellar groove absent; apical half of suture strongly raised, with a sharp keel, terminating as sharp prominent lobes; humeri prominent, and elytral margins sinuate, strongly contracted behind humeri.

Mesoventrite process

Not developed, a small transverse plate with truncate anterior margin, separated from the intercoxal process of the metaventrite by a deep transverse groove and row of erect setae.

Abdomen

All ventrites with scattered short scale-like setae and punctures in both sexes; punctures U-shaped.

Legs

Fore tibia with two long and curved teeth on external edge; claws symmetrical; posterolateral corner of hind coxa not produced, evenly rounded; hind femur straight, without lobe on ventral edge; hind tibia slightly thinner than femur, straight, expanded at apex, with small median tooth and internal fringe of long setae; hind tibial spurs thin and sharp in both sexes.
