Structure

Body - elongate-ovoid; dorsally flattened. Length 3.0 mm -5.5 mm, width 2.0 mm -3.5 mm.

Head - subtriangular or triangular; head elongate, as long or longer than pronotum, porrect orientation (clypeus almost horizontal); jugae longer than clypeus either apically free (not meeting) or joined (meeting), anteriorly pointed, laterally carinate; antennifer processes absent; five antennal segments, first segment shorter than distance between eyes, insertion into head below the ventral margin of eyes; bucculae elongate (extending posteriorly behind antennifers); vertex convex to slightly flattened; labium elongate, reaching between middle and hind coxae, first segment equal in length to bucculae; eyes not stylate.

Pronotum - calli present and well developed, present as raised and polished areas next to dark shallow pits; humeral angles rounded or subangulate; lateral margins slightly explanate; anterolateral margins straight to convex with no crenulations; posterolateral margins straight to slightly sinuate; posterior margin straight.

Scutellum - U-shaped, enlarged but not reaching posterior of abdomen; apex broadly rounded; Y-shaped raised area can be either present or absent; median calli present or absent; lateral calli present as polished areas with dark, shallow pits adjacent.

Thoracic sterna - uniformly sulcate; prosternum deeply sulcate, margins with processes.

External efferent system - covering up to half the metepisternum; peritreme greatly reduced and possibly difficult to observe, rounded apically.

Hemelytra - macropterous; shorter or equal to abdomen in length; membrane veins linear and mostly subparallel.

Legs - tibiae sulcate.

Abdomen - connexiva visible dorsally beyond hemelytra; laterotergites unarmed.
