Opisthogastric region with reduced number of four pairs of setae (JV1, JV2, JV5 and ZV2 present; JV3 and JV4 absent), two of which on ventrianal shield (JV2, ZV2). Setae JV1 and JV5 on soft integument. Ventrally inserted setae smooth and needle-like, except JV5, longer and slightly spine-shaped. Gnathosoma relatively small. Corniculi weakly sclerotised distally, membranous, with undivided apex. Cheliceral digits relatively small, fixed digit with two teeth on medial masticatory area. Epistome subtriangular, with irregularly and obtusely curved apex. Palptarsal apotele three-tined. Genu III, and tibiae III–IV with two anterolateral and one posterolateral setae.
