Diagnosis. Female. Body black with metallic green or blue lustre, with coxae and femora black or dark brownish with an iridescent tinge. Head and mesonotum finely punctate-reticulate. Antenna 12-segmented with two anelli. Fore wing with stigmal vein normal, diagonal, at an acute angle to the wing margin, with four rounded sensilla distally.
