Male holotype (MNHN 13/1970, from Andohahelo, Fort Dauphin, Madagascar). Total length 2.39, carapace 0.97 long, 0.82 wide. Abdomen 1.30 long, 1.40 high. Carapace tilt angle 62.38°, tilt height (CtH) 2.57, constriction 0.54, head length 1.22, neck length 1.29 (Fig. 2). CtH divided by carapace length 2.65. Cephalon with AME on large bulge, and with postocular pointed head (Fig. 18
<normalizedToken originalValue="A–B">A-B</normalizedToken>
). Cephalon with 4 small post-ocular spines at the crown, not on protrusions. Chelicerae 2.07 long, and with a short spine 0.31 from base of chelicerae that projects perpendicular to the cheliceral cuticle. Femur I 2.99 long. Sternum 0.41 long, 0.65 wide, but completely fused to the carapace; measurements were taken based on approximations of where the original sternum edge would have been. Carapace and sternum reddish brown with white setae, chelicera light reddish brown. Legs beige with reddish brown annulations on tibia and metatarsus. Abdomen beige, mottled with brown and with tufts of white setae (Fig. 18A). Pedipalpal bulb with a membranous sac above the base of the embolus, with a greatly exposed embolus that is encircled by the conductor. Conductor with basal part an uneven ridge shape (see the basal

<normalizedToken originalValue="F–G">F-G</normalizedToken>
), with distal part that is narrow as it encircles the embolus, with a large, broad, bulge before tapering off. Conductor with lateral process that is as wide as long (Fig. 18
<normalizedToken originalValue="F–G">F-G</normalizedToken>
, asterisk). Embolus broad but tapering at tip to a long, fine wire (Fig. 18I); the embolus tip is broken off of the left pedipalp (Fig. 18G, arrow), but is entire in the right pedipalp (Fig. 18I).

the sternum is fused to the carapace, so the sternum measurements were based on an approximation of where the sternum border would be if this fusion was absent. In the type specimen the embolus tip is broken off in the left pedipalp (Fig. 18G - arrow), however the right pedipalp shows that the embolus tip is curved and much longer (Fig. 18I).
