Carapace.
Yellow with a brown X-like fovea and black eye margins. Cephalic parallel-sided, barely

Retromargin has four teeth smaller than those in promargin, apical tooth strongly triangular and broad basally, third tooth the smallest and basal tooth the largest. Pedipalp yellow with hairy and spinous tarsus, tarsal claws without teeth. Dorsum of pedipalp’s tibia bears three trichobothria in increasing length towards midlength, submedian trichobothrium the longest, approximately
