DIAGNOSIS (after Hinojosa-Díaz & Engel, 2011a): Mid-sized metallic bees, with rather robust habitus; both sexes with tridentate mandibles and pronotal dorsolateral angles projected as acute prong or lamella; female metabasitarsus trapezoidal with noticeably narrow distal margin; male mesotibia with two tufts, anterior tuft ellipsoidal, occupying about one-third of outer mesotibial surface, posterior tuft rounded in a variety of shapes; male mesobasitarsus characteristically elongate and slender, distal mesotarsomeres (particularly second mesotarsomere) unmodified; inner surface of male metafemur with ventral margin distinctively straight; male metatibia scalene triangular, metatibial organ slit basal and distal sections separated by a constriction distinctively narrower than width of contiguous basal section, basal section ellipsoidal, distal section separated from ventral margin of metatibia by less than its own length; ventral margin of inner metatibial surface with a blunt projection adjacent to spur attachment; male metabasitarsus roughly rectangular, ventral margin roughly straight in respect to sagittal body plane, appearing truncate and without noticeable projections of posterior margin. Eighth metasomal sternum of male with lateral edges of posterior section deeply invaginated, lobes strongly projected; posterior margin of apical process of gonocoxite oblique (inner-posterior corner displaced posteriad); lateral area of gonostylar process of gonocoxite truncate; spatha surface with longitudinal striae; dorsal sector of lateral section of gonostylus convex, covered with distinctive plumose setae, gonostylar ventral lobe thumb-like.
