Carapace length is shorter in females than in males. Carapace reticulation slightly weak at anterior half in female. Second podomere of male right fifth limb divided into 3 parts (IIa, IIb, IIc). IIa and IIb completely fused, and only with remaining segment boundary. IIb and IIc with faint borderline remaining between podomeres. In male copulatory organ, right distal lobe with triangular outline and sharp linearly tip, left one with hump-shaped tip.
