Diagnosis
Most specimens of this species can be separated from Bembidion grandiceps using the characters listed for that species. Also, specimens of Bembidion planum have a narrower head and pronotum and the elytral apex slopes slightly.
Most specimens of this species can be separated from Bembidion fugax by the more weakly impressed 6th compared with 5th elytral stria, and the frontal furrows end just behind the posterior supra-orbital puncture and are little divergent. Specimens tend to be paler and slightly smaller than those of Bembidion fugax, and in most specimens have strongly-impressed microsculpture over the entire pronotum.
