Diagnostic Notes
Adult Female

Body usually pyriform, with the head and thorax membranous, and pygidium sclerotized but small in comparison to body. Lobes in 3 pairs, well developed, fourth pair represented by serrations on margin. Plates fimbriate, but often some clavate, absent from lateral to position of the fourth lobes. Dorsal ducts 1-barred, long and slender, in lines or furrows. Marginal paraphyses well developed, usually longer than the lobes, arising from inner and outer basal angles of the lobes, also with 1 between each second and third lobe. Anus situated near apex of pygidium. Perivulvar pores present in 4 or 5 groups.
