Description. Body length 3.8–9.3 mm; color dark; elytra without variegated color pattern; legs mostly dark. Microsculpture absent on head and pronotum, usually present and well developed on elytra (rarely absent or poorly developed). Forebody narrow in comparison to elytra. Head. Antennae filiform, very long, reaching about basal third of elytra. Frontal furrows not prolonged on clypeus. Mentum with medial tooth truncate or subtruncate at tip (entire in other subgenera). Submentum usually with six setae (rarely with four setae). Ligula with two fused setae. Palpi with penultimate labial segment bisetose on anterior margin. Thorax. Pronotum usually moderately convex (rarely strongly convex), cordate, widest before middle; laterobasal carinae absent; setiferous puncture absent near posterolateral angle; laterobasal foveae poorly developed. Epipleura (in dorsal view) exposed in front of posterolateral angles. Elytra. Usually subdepressed (rarely slightly convex), oblong-elongate, widest before middle. Shoulders angulate. Scutellar striole usually consisting of a row of punctures (rarely of a line and punctures). Striae complete or incomplete, punctate. Intervals usually depressed (rarely slightly convex); interval 3 with three to five discal setiferous punctures; interval 5 with two discal setiferous punctures (absent in other subgenera). Subapical sinuations feeble. Apical striole present; preapical setiferous puncture not isolated. Sutural apices angulate or rounded. Abdomen. Last visible sternum (sternum VII) of female with or without numerous short setae in addition to four long ambulatory setae. Aedeagus. Internal sac with a brush sclerite. Parameres.
