Male holotype (CASENT9012014, from Parc National Ranomafana, Madagascar). Total length 2.10, carapace 0.95 long, 0.85 wide. Abdomen 1.10 long, 1.26 high. Carapace tilt angle 72.5°, tilt height (CtH) 1.72, constriction 0.52, head length 0.82, neck length 0.81. CtH divided by carapace length 1.81. Cephalon with AME on a small bulge, and with 4 small post-ocular spines (although it is difficult to tell as the anterior pair is missing, rudimentary 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 1.59 long, and with a spine 0.25 from base of chelicerae that projects perpendicular. Femur I 2.03 long. Sternum 0.63 long, 0.40 wide. Carapace, chelicerae, sternum, and legs reddish brown with white setae; patellas, tibias, and metatarsi light tan. Abdomen mottled with dark brown and light yellow patches, with light circular patches on the dark brown portions, with white setae. Pedipalpal bulb with a large membraneous sac above the base of the embolus, with a greatly exposed embolus that is encircled by the conductor (Fig. 21

Female paratype (CASENT9012341). Total length 2.24, carapace 0.87 long, 0.80 wide. Abdomen 1.18 long, 1.48 high. Carapace tilt angle 67.5°, tilt height (CtH) 1.50, constriction 0.50, head length 0.78, neck length 0.73. CtH divided by carapace length 1.73. Cephalon with AME on a small bulge, and with 4 small post-ocular spines (one is broken off or missing) on the crown of the cephalon, and 1 spine between the LE and AME (on each side, for a total of 2). Chelicerae 1.54 long, and with small spine 0.29 from base of chelicerae. Femur I 1.82 long. Sternum 0.60 long, 0.40 wide. Cephalothorax colors as in male.
