Carabid - Philodes alternans

Small carabid that has been frustrating me.

Antennae setose starting at segment 2; terminal maxillary palp has long conical shape; one pair supraorbital setae; one pair anterior lateral pronotal setae, plus additional interior pair (barely visible as pale dots); some elytral stria with rows of 10+ erect setae, left side on 2-5-7, right side on 2-3-5-7 on this specimen, on a second specimen setae are on 2-5-7 both sides.

Acupalpus alternans (LeConte, 1853)
fits image, location, and detailed decriptive account. See type specimen. My reference specimen is paler yellowish throuhout as reflected by replaced name Stenolophus testaceus (LeConte, 1844).

would be cool
but the degree of basal pronotal constriction is different and I can see no evidence of the amount of setae seen on my specimen in either Kyle's photo or the type photo on MCZ.
