Male holotype (USNMENT01377199, from Parc National Masoala, Madagascar). Total length 1.79, carapace 0.75 long, 0.70 wide. Abdomen 0.97 long, 0.81 high. Carapace tilt angle 59.5°, tilt height (CtH) 1.72, constriction 0.32, head length 0.86, neck length 0.89 (Fig. 2). CtH divided by carapace length 2.29. Cephalon with AME on large bulge. Cephalon with 4 small post-ocular spines on the crown of the cephalon, with the posterior pair on large protrusions and the anterior pair not on protrusions, and 1 small spine between the LE and AME (on each side, for a total of 2). Chelicerae 1.50 long, and with a short spine 0.68 from base of chelicerae, projecting downward. Femur I 1.89 long. Sternum 0.50 long, 0.32 wide. Carapace, chelicerae, and sternum dark reddish brown with white setae. Coxae and legs lighter brown, with darker annulations on tibiae and metatarsi. Abdomen mottled brown and beige, with a bright white patch on each lateral side, with tufts of white setae (Fig. 22A). Pedipalpal bulb with a small membranous sac above the embolus base, with the base of the conductor small and triangular with a cluster of small bumps and pores (Fig. 22
