Diagnosis. As for genus.
Description. Both sexes: After fixation, without remarkable colour patches. Idiosoma broadly rounded. Dorsal plate with traces of sutures indicating the fusion of shoulder plates. Distal edge of Cx-I flanking gnathosomal bay smooth, lacking any denticles or knob-shaped protrusions; Cxgl-4 well developed. Genital field elongated, with rounded anterior margin, lateral margins posteriorly slightly converging. P-2 ventral margin concave; P-3 anterior and posterior to ventral projection concave; P-4 ventral setae associated with short, pointed denticles.
