Moved from Elaphropus.

is my determination upon re-examining this photo-vouchered specimen 7 years later, along with a review of the sketchy literature and comparing to the type specimen imaged here. Thanks Tom for this species new to BugGuide and new to my synoptic set.

This far western species is distinguished from the widespread similar species E. dolosus by the following characters (rapax vs dolosus):

(1) Dorsum uniformly light brownish-red vs brownish-yellow.

(2) Pronotum with transverse basal sulcus bearing three large medial punctures widely spaced followed laterally by smaller punctures vs one large central puncture followed laterally by small punctures evenly sized and spaced.

(3) Elytron with sutural stria distinctly reaching basal pore puncture and contributing to its border vs not so distinctly prolonged.

These western carabids are a real challenge. Peter, thanks for all your work.

based on my microscopic examination of this specimen. Elaphropus is badly in need of revision as the western fauna especially is inadequately described. I hope to return to this specimen later after doing some literature hunting. Thanks Tom.
