Explanation of Names
Harpalus texanus Casey 1914
Identification
PWM update 4.x.2021. Very similar to H. pensylvanicus. Reliable ID should be based on examination of the internal sac of the aedeagus --see Ball & Anderson (1962). Otherwise, one can evaluate the more accessible apex of the aedeagus.
Aedeagus with shaft overall slightly wider; apex point slightly rounder vs shaft narrower; apex point sharper;
Pronotum with basal groove laterally more or less interrupted by punctures, but not consistently so and never extensively (extensively interrupted in H. pensylvanicus);
elytra much shinier (especially in males);
Pronotum slightly more constricted toward base;
Pronotal base with areas around depressions more convex and less uniformly punctate and rugulose vs flat portion across base larger, extending anterolaterally to sides more widely flattened, punctate coarsely and uniformly.
Range
Coastal Plain, NC-FL-eTX (1)
