  • Color: Reddish-brown.
  • Body: The carapace is finely granulate, tergal region with a typical pattern. THe eyes are separated from the anterior margin of the carapace by a distance equal to 1/3 of the length of the scute, separated from each other by a distance equal to 2x their diameter. The shape of the genital operculum is shown in Fig. 754, sub-triangular, only slightly longer than wide.
  • Genitalia: The aedeagus is slender and tubular, with a pair of small spines at the mid-ventral surface. 6 setae present at the base of the aedeagus as shown in Fig. 753. Dorsal and ventral plates absent.
  • Chelicerae: Typical.
  • Pedipalls: (Fig 751). There is a prominent swelling on the ventral surface of the trochanter and the proximo-ventral surface of the femur. The disto-dorsal process of the tibia is strong, digitiform. The tarsus is slender and straight, tarsal spine small, stout, equal to ½ length of tarsal claw.
  • Legs: Few small tubercles on femora, legs otherwise smooth. Tarsal formula Tarsal claws 3 and 4 as shown in Fig. 755, only 4 lateral branches, accessory spine present, arolium extending beyond median branch.

  • Female: Similar in structure to male except in a few characters. The genital operculum is wider than it is long. The pedipal is as shown in Fig. 752, 3 small tubercles on the proximo-ventral surface of the femur, lacking tibial process and tarsal spine.
  • Measurements (mm): Scute: 1.25x1.13; Legs: 2.39, 2.77, 2.51, 3.19; Pedipalp: 2.09; Chelicera: 0.47
