Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Containing group: Bembidion (Bracteon)

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).

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
