Body - Elongate, parallel-sided; dorsally convex. Length 7.9 mm -11.3 mm; width 4.3 mm -7.7 mm.

Head - Subtriangular, porrect (clypeus horizontal) to moderately dorsoventrally orientated, shorter than pronotum; jugae shorter than clypeus, apically pointed, laterally carinate; antennifer processes present; five antennal segments, first antennal segment shorter than distance between the eyes, inserted below mid-height but above ventral margin of the eyes; bucculae elongate (posteriorly beyond antennifers); vertex cross-sectional shape flattened; labium reaching between middle coxae and second abdominal sterna, first labial segment as long as bucculae; eyes slightly substylate, directed laterally.

Pronotum - Calli present; anterior lobe surface flat; humeral angles angulate and slightly expanded laterally; lateral margins rounded; anterolateral margins simple and concave, posterolateral margins straight to slightly sinuate; posterior margin straight.

Scutellum - Triangular, apex narrowly rounded; lateral calli present; medial callus absent.

Thoracic sterna - Prosternum shallowly sulcate with margin processes; mesosternum with a low raised keel; metasternum sulcate.
