Female holotype (MCZ, from Parc National Ranomafana, Madagascar). Total length 1.91, carapace 0.74 long, 0.69 wide. Abdomen 1.06 long, 1.24 high. Carapace tilt angle 64.4°, tilt height (CtH) 1.32, constriction 0.44, head length 0.68, neck length 0.64. CtH divided by carapace length 1.77. Cephalon with AME on a small bulge. Cephalon with 4 small post-ocular spines (one is missing or broken off) on the crown of the cephalon, not on protrusions, and 1 spine between the LE and AME (on each lateral side, for a total of 2, but broken off on the right side). Chelicerae 1.33 long, and with a spine 0.24 from base of chelicerae, however, the spines are broken off and only the socket remains; the socket shape suggests the spines would projecting perpendicular to the cheliceral cuticle. Femur I 1.46 long. Sternum 0.51 long, 0.35 wide. Carapace, chelicerae, sternum, and legs reddish brown with white setae; patellas lighter brown. Abdomen anterior dark brown with light circular patches and posterior light tan; abdomen with white and brown setae (Fig. 15A). Female genitalia with a small and simple FSGP, with

Male paratype (USNMENT01377173). Total length 1.64, carapace 0.78 long, 0.68 wide. Abdomen 0.83 long, 0.97 high. Carapace tilt angle 66.7°, tilt height (CtH) 1.31, constriction 0.44, head length 0.72, neck length 0.61. CtH divided by carapace length 1.69. Cephalon with AME on a small bulge, and with 4 small post-ocular spines (one is missing or broken off) on the crown of the cephalon, and 1 spine between the LE and AME (on each side, for a total of 2). Chelicerae 1.23 long, and with small spine 0.17 from base of chelicerae (Fig. 15A). Femur I 1.63 long. Sternum 0.49 long, 0.32 wide. Cephalothorax colors as in female. Abdomen mostly light tan, but mottled with dark brown areas that have light circular patches; with white and brown setae; posterior of abdomen with bright white areas. Pedipalpal bulb with a small membraneous sac above the embolus base, with a greatly exposed broad and dark embolus that is encircled by the conductor (Fig. 15
