Diagnosis[]

(from Forster, 1954[1])

  • Color: The entire animal is golden-brown.
  • Body: Carapace closely covered with small granules, tergal region shiny,with a regular pattern formed by single rows of small granules as shown in Fig. 771. The free tergites and sternites are smooth. The eyes are set at about ¼ of the length of the scute, and are separated from each other by a distance equal to 3x their diameter. The genital operculum is triangular in shape, apex sharply pointed, width at base equal to 2/3 of its length (Fig. 774).
  • Genitalia: The aedeagus is slender, tubular, with a strong elbow near the mid-point, ventral plate extending to elbow, with a pair of long setae near the base, each set in a socket, and a similar, but smaller sub-distal pair as shown in Fig. 773.
  • Chelicerae: Basal segment with a distended area on the disto-dorsal surface. Second segment with low setose tubercles on the dorsal surface.
  • Pedipalls: (Fig 772). There is a small conical tubercle present on the proximo-dorsal surface of the femur and a similarly shaped, smaller tubercle on the distal pro-lateral surface of the trochanter. The proximo-ventral surface of the femur is slightly raised but does not form a prominent process. The tibia lacks a disto-dorsal process. The tarsus is slender, straight,with a strong disto-ventral spine, 2/3 of the length of the tarsal claw.
  • Legs: Smooth. Tarsal formula 3.5.4.4. Tarsal claws of legs 3 and 4 as in Fig. 775, arolium extending well beyond the median branch, terminated sharply.
  • Measurements (mm): Scute: 1.06x0.88; Legs: 2.01, 2.77, 2.34, 3.08; Pedipalp: 1.78; Chelicera: 0.54
  • Female: Similar to male. Pedipalp more slender, without tubercles or tarsal spine. Genital operculum wider than it is long.
  • Measurements (mm): Scute: 1.05x0.92; Legs: 1.96, 2.61, 2.29, 3.04; Pedipalp: 1.38; Chelicera: 0.48
