Buccal apparatus Bucco-pharyngeal apparatus of the Isohypsibius type, without ventral lamina. Oral cavity armature absent or not visible under PCM. Pharyngeal bulb oval with three macroplacoids and a microplacoid. All macroplacoids without constrictions. Macroplacoid length sequence 2<1<3. Legs and claws Claws of the Isohypsibius type, similar in size and shape on all legs. All main branches with well developed accessory points. Smooth lunules present on all claws, slightly larger on claws IV. Cuticular bars present under internal claws I-III. Eggs Smooth, round, white, and deposited in exuvium (4-6 eggs per exuvium).
