From Wilson (2003): DIAGNOSIS A medium-sized, yellow member of the flavens group; the major has shallow but well-developed antennal scrobes; rugoreticulation across all of the occiput; a small mesonotal convexity, and angulate lateral postpetiolar margins, as well as posteriorly directed propodeal spine and rugoreticulate humerus. Resembles ademonia and peltastes, but easily distinguished by many features of sculpturing, development of the scrobe, and presence in the major of the mesonotal convexity, as illustrated.

MEASUREMENTS (mm) Lectotype major: HW 0.84, HL 0.92, SL 0.44, EL 0.12, PW 0.44. Paralectotype minor: HW 0.44, HL 0.46, SL 0.42, EL 0.08, PW 0.30.

COLOR Major: appendages and gaster clear yellow, rest of body a slightly contrasting reddish yellow (“orange”).
