Agonum decorum green-glabrous form --det. J. Liebherr

Western "Agonum decorum green/blue glabrous morph"
(= junior synonym Agonum californicum Dejean) versus typical eastern "Agonum decorum red hirsute morph" are more or less the designations used by Liebherr (1994) but I would prefer that the morphs be returned to distinct species.

PWM note: Lth:628 states forebody A. californicum greenish or bluish; % corroborated by 1 glabrous ex fr CA-Inyo Co w bluish forebody.
