Buccal armature with an anterior band of small teeth that is difficult to observe; a second, posterior row of longitudinally elongate teeth, and a posterior system of three dorsal and three ventral ridges. Claws stout with well developed accessory points; smooth lunules present. In addition, the first three pairs of legs have a faint cuticular bar present near the lunules. The eggs, freely laid, have processes with a conical basal portion abruptly continuing in a long, sharpened, terminal portion with some bubble-like structures, whereas the basal portion presents a faint, almost invisible, reticular ornamentation.
