Bembidion dyschirinum

University of Alberta E.H. Strickland Entomological Museum Read more about this collection »

IdentificationMember of the lampros group (subgenus Metallina). Black, usually with faint aeneous lustre, base of antennae (at least 1st segment below) and legs paler, reddish or piceous, but femora always darker than the tibiae which, however, have the extreme base darkened. Head with frontal furrows arcuate, no pronounced longitudinal ridge between anterior and posterior supraorbital punctures. Prothorax hardly constricted at base, latero-basal carinae long, straight, or even slightly converging at tip. Elytral striae more abbreviated in apical half, usually more finely punctured, the rudimentary 7th stria, behind shoulder, as evidently punctate as the 6th. Length 2.9 to 3.8 mm.
