Bembidion velox
David R. Maddison
Adult External Characteristics
Elytral interval 3 with distinct mirrors, in some specimens on 2 through 5 as well. Pronotum without long basilateral carina; if basilateral carina present, then short, not extended to pronotal base; midlateral seta present.
Male Genitalia
Central sclerite complex of male genitalia far removed from basal orifice, with ridge on right lobe. Ostial microtrichial patch extended dorsally as a prominent dorsal field of long microtrichia. Left-most central membranes with small, sparse, heavily sclerotized scales, sac thus with a peppered appearance. Without the "pillow" characteristic of B. lapponicum.

Comparison with Related Species
Compare with:
The short basilateral carina of pronotum, isolated from the base, distinguishes adults of this species from those of the allopatric B. carinula. As well, the elytra of B. velox are generally narrower and more nearly parallel-sided. Aedeagal characters of B. velox, as noted above, are also distinctive.
Members of B. velox can be confused with B. lapponicum; see the discussion under that species.
Geographic Distribution
From western France north to Scandinavia, east to the Irtysh and Jenesei Rivers of Russia, and Shenyang, China.
Habitat
On pure, barren sand on the banks of larger lakes and rivers, as well as on banks of bodies of salt water (for example, the Baltic Sea).
