DIAGNOSIS. As for the family.

Holotype. Gender and biological age of the specimen unclear.

Repository. Deposited in the private collection of Antoun Estephan (Frankfurt, Germany).

Range. Lebanese amber, 135–120 Ma.

Measurements (in mm). Carapace. Anterior width 1.06? (right lateral edge obscured). Width of carapace at lateral eyes 0.89; median length 0.98. Carapace + mesosoma length 2.82. Chelicerae. Width at the base 0.29. Right pedipalp. Femur length 1.06, width 0.27; patella length 1.21, width 0.37; chela length 2.10, width 0.34; chela palm length 0.82, width 0.34; movable finger length 1.28. Legs. Leg III tarsus length (dorsal 0.34, ventral 0.41), tarsus basal width 0.09. Metasoma I length/width (L/W) 0.53/0.44, 1.2. Total length: extrapolated to about 6.0 (after Lourenço, 2001).

Description. Yellowish brown, with reddish brown patches on pedipalp. Weakly to moderately granular. Anterior margin of carapace with a moderate median concavity. Anterior median superciliary carinae vestigial; other carinae obsolete. All furrows moderate to weak. Median ocular tubercle distinctly anterior to the center of carapace. Median eyes separated by almost twice their diameter. With two pairs of lateral eyes, the most distal pair (the third) appears to be missing. Pedipalps: right pedipalp well visible, see below for detailed discussion of trichobothria. Chelicerae: dentition was not fully visible but the ventral distal tine of movable finger is longer than the dorsal distal denticle. Sternum not observable. Pecten not available, only a few scattered teeth observable. Without tibial spurs on legs III–IV; with pedal spurs; tarsal armature reduced. Tergites weakly granular. Tergites I to VI with three longitudinal carinae, moderate to strong. Tergite VII pentacarinate. Sternites I–III not clearly visible, IV–VII rather smooth, with median longitudinal punctations; small oval to circular stigma visible on sternites V and VI. Metasomal segments II to V (and telson) missing. Metasomal segment I with 10 carinae; ventral carinae parallel; dorsolateral with spinoid granules.
