GABON (Congo Française) • ♂; Fernan Vaz ; L. Fea leg.; MNHN AR3112 . Collected as commensal or parasite of ants of Anochetus Mayr, 1861 .

Note

The specimen is completely bleached and the description lacks therefore some essential details; limits of secondary eyes, chilum, spines and clypeal setae are invisible.

Description translated from Latin

Cephalothorax reddish orange, almost smooth, short and with sparse yellowish setae, AME with black surrounding. Anterior eyes in straight row, almost touching and of different size; AME dark, rounded, and diameter one fourth longer than of remainder, which are white. Posterior eyes very small in a procurved row; PME, at least three times more distant from each other than from the PLE. Clypeus slightly wider than AME. Abdomen pale yellow with whitish setae. In front with small, reddish ovoid scutum. Chelicerae well developed, slightly rugose, with elongate dental furrow, anterior one provided with two small widely separated teeth. Sternum, mouthparts and legs pale yellowish brown; endites twice as long as wide; legs fairly long with short setae; all femora with one dorsal spine in distal half; tibia I with three pairs of small spines, metatarsus I with similar pairs of spines; other segments spineless; male palp with slightly darker tarsus, femur with small dorsal spine at distal tip; patella slightly longer than wide, slightly convex, spineless; tibia almost as long as patella, distal part with reddish apophysis composed of two parts: one compressed but sharp, the apical one much more slender and curved, with inferior ridge, anteriorly a distal sharp hook, posteriorly curved into a fairly long tubercle forming a channel; cymbium oval, with long sharp tip; bulbus large, fairly convex oval, rounded at base; embolus strong, long, curved.
