Male holotype (CASENT9062702, from Parc National Befotaka-Midongy, Madagascar). The abdomen of this specimen is missing making some measurements impossible. Carapace 1.11 long, 0.89 wide. Carapace tilt angle 76.7°, tilt height (CtH) 1.80, constriction 0.76, head length 1.02, neck length 0.87. CtH divided by carapace length 1.62. Cephalon with AME virtually flush with surrounding cuticle, and with 2 short modified spines at the apex. Chelicerae 1.78 long, and with long spine 0.19 from base of chelicerae and projecting perpendicular to the cheliceral cuticle (Fig. 12A). Femur I 1.98 long. Sternum 0.71 long, 0.42 wide. Carapace, chelicerae, sternum and legs reddish brown with white setae. Legs with darker annulations on tibiae and metatarsi. Abdomen color unknown. Pedipalpal tegulum of the "

The male and female may not be conspecifics, however based on morphology they likely belong in the "enclosed embolus group." Future molecular work as well as additional collection of specimens from more localities can help resolve these issues.
