Description:

Female.

Apterous; length 5.87 mm. Head black, with mandibles, clypeus, genae and two short stripes along orbits testaceous; antennae testaceous, with segments 3, proximal half of 4, 8–10 darkened; mesosoma black, with sides of pronotum testaceous; gaster brown; legs testaceous, with clubs of femora slightly darkened. Antennae clavate; antennal segments in following proportions: 12:6:26:17:15:11:10:9.5:8.5:10. Head excavated, shiny, with face smooth and without sculpture and vertex, temples and occiput granulated; frontal line complete; occipital carina absent; POL = 2; OL = 2; OOL = 9; greatest diameter of posterior ocelli = 2. Maxillary palpus with 6 segments; labial palpus with 3 segments. Pronotum crossed by strong transverse impression, with anterior collar and disc shiny, smooth and without sculpture; sides of pronotum partly granulated and partly sculptured by a few longitudinal striae. Scutum shiny, sculptured by a few longitudinal striae, laterally with 2 strong points situated on sides of scutellum. Scutellum shiny, smooth, inclined. Metanotum very short, transversely striate and deeply hollow behind scutellum ( Fig. 30 ). Metathorax + propodeum shiny, with disc and anterior surface smooth and without sculpture; posterior surface of metathorax + propodeum sculptured by numerous transverse striae; mesopleura and metapleura transversely striate. Mesometapleural suture distinct and complete. Fore tarsal segments in following proportions: 20:3.5:7:18:27. Enlarged claw ( Fig. 31 ) with small subapical tooth and 1 row of 6 peg-like hairs + 1 hair. Segment 5 of front tarsus ( Fig. 31 ) with two rows of 7 + 13 lamellae; distal apex of segment 5 with group of approximately 21 lamellae. Tibial spurs 1, 0, 1.

Male. Unknown.

Holotype: ^“ BURKINA FASO: Kompienga Prov. , 20 km S Pama, 3–24.ix.1988, savana, interception trap, F. Génier, M. Sanborne & F.M. Tou ”; [red] “ Gonatopus savanensis sp. n. M. Olmi det. 2006, ^” (CNCI). Hosts: Unknown.

Comparison: G. savanensis belongs to the G. incognitus group. The female is similar to those of G. operosus Olmi, 1993 , and G. trochantericus (Benoit, 1953 b) , but it may be distinguished by the position of the subapical tooth of the enlarged claw ( Fig. 31 ); it is in fact nearer the distal apex than in the other two species (Olmi 1984, figs 1135, 1136).
