  • Color: Reddish-brown
  • Body: Carapace finely and closely granulate, tergal region with pattern formed by lines of granules. The eyes are separated fron the anterior margin of the carapace by a distance equal to ¼ of the length of the scute,separated from each other by a distance equal to 3x their diameter. The shape of the genital operculum is shown in Fig. 737, 2x as long as wide at the base.
  • Genitalia: Aedeagus long, slender, tubular, with a short ventral spine at about ¾ of its length. There are two long and slender setae on each lateral margin at the base, the dorsal seta being longer (Fig. 736). There are 3 smaller setae on the ventral surface.
  • Chelicerae: Typical.
  • Pedipalls: (Fig 734). There are strong protruberances on both the dorsal and ventral surfaces of the trochanter as shown in Fig. 735, and on the proximo-dorsal and sub-proximo-ventral surfaces of the femur. Patella with a conical mound on the ventral surface. The disto-dorsal process of the tibia is digitiform, blunt apically. The tarsus is slender and straight. Tarsal spine short, less than ½ the length of the tarsal claw.
