Type species. Bembidium anchonoderum Bates, 1878a , by original designation.

Description. Body length 2.8–5.5 mm; color dark; elytra without variegated color pattern; legs dark or pale. Microsculpture usually present (rarely absent), poorly or well developed. Forebody usually moderately wide in comparison to elytra (rarely very wide or narrow). Head. Antennae usually filiform and moderately long, reaching about elytral shoulders (rarely submoniliform and rather short, reaching about elytral base). Frontal furrows not prolonged on clypeus. Submentum with six 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 or not exposed in front of posterolateral angles. Elytra. Usually moderately convex (rarely depressed), subovate (sometimes elongate or ovate), widest about middle (rarely widest behind middle). Shoulders usually moderately rounded (rarely angulate or obtuse). Scutellar striole usually consisting of a row of punctures (rarely of a line and punctures). Striae complete or incomplete, punctate; stria 3 with three discal setiferous punctures. Intervals subdepressed or slightly convex; interval 5 without discal setiferous punctures. Subapical sinuations feeble. Apical striole usually present (rarely absent); preapical setiferous puncture not usually isolated. Sutural apices angulate. 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.
