5(4)   Dorsal surface bright metallic green or blue; punctures on disc of pronotum relatively sparse, distance between adjacent punctures 3-5 times diameter of puncture

-        Dorsal surface dark brown or black, rarely with slight green color; punctures on disc of pronotum relatively dense, distance between adjacent punctures at most about diameter of puncture

6(5)   Reddish band along each anterolateral margin of pronotum usually infuscated near middle; basal plates usually completely fuscous or black; ventral margin of pygophore in ventral view with small, medial, circular emargination; posterior wall of pygophore in caudal view completely lacking black spicules (Mexico to Costa Rica)
