Pedipalps yellowish densely marked with brownish spots better marked on the femur and patella; chela paler than patella; fingers brownish with the rows of granules slightly reddish. Legs yellowish, densely marked with brownish spots. Carapace moderately granular; anterior margin with a very slight median concavity, almost straight; all furrows moderate to weak. Tergites moderately to weakly granular; median carina moderate to weak in all tergites; tergite VII pentacarinate. Sternum subpentagonal. Pectines very small; pectinal tooth count 10-10 in female. Sternites smooth with short semi-oval spiracles; VII with a few granulations and vestigial carinae. Metasomal segments with 10-10-10-8-5 crenulate carinae; intercarinal spaces moderately to weakly granular. Telson with a pear-like shape, almost smooth with three ventral carinae; aculeus very short and moderately curved; subaculear tooth strong and almost rhomboid. Pedipalp femur pentacarinate; patella and chela with a few vestigial carinae; internal side of patella with some vestigial granules; all sides feebly granular, almost smooth; movable fingers with 6/7 almost linear rows of granules; two accessory granules present at the base of each row; extremity of movable fingers with three accessory granules.
