Diagnosis. Dorsal shield not completely covering the dorsum; unsclerotized cuticle between marginal and dorsal shield or between marginal and ventrianal shield without setae. Three pairs of glands on opisthosomal soft cuticle between the marginal and ventrianal shields. Marginal dorsal shield present, bearing one pair of setae (R). Marginal dorsal shield fused anteriorly with dorsal shield at level of setae s3, free lateral, fused or free posteriorly. Dorsal shield in podonotal region holotrichous with 22 pairs of setae and one unpaired medial setae; all relatively short; opisthonotum hypotrichous with 16 pairs of setae. Sternal shield with three pairs of setae, st3 setae set close together at the posterior margin of the shield; two pairs of sternal lyrifissures and a pair of glands. Metasternal shields free from sternal shield but fused together, with short setae st4 and lyrifissures iv3. Female genital shields include two triangular latigynial shields, each with two setae and a nearly rectangular small mesogynial shield; anterolateral margins of mesogynial shield overlapped by latigynial shields. Vaginal sclerites club-like, well sclerotized; with distinct lateral projections. Ventrianal shield hypotrichous, with six pairs of setae, four pairs of lyrifissures and a pair of glands (gv2). Ventrianal shield expansive, continuously united with peritrematal, exopodal and metapodal shields anterolaterally; posterior margin rounded, not extending to posterior margin of idiosoma. Ventrimarginal shields absent. Stigmata between coxae III and IV; peritremes extending no further than the middle region of coxae II. Movable digit of chelicerae in males with one brushy excrescence and a basal thumb like structure as long as movable digit; movable cheliceral digit in females with three brushy excrescences and a comb-like structure. Legs I without claws; tarsus IV without a distinct ventral sclerite.
