Type material.

HOLOTYPE: ♀, CENTRAL AFRICAN REPUBLIC: SANGHA-MBAÉRÉ PREFECTURE: Réserve Spéciale de Forêt Dense de Dzanga-Sangha, 12.7 km 326°NW Bayanga, 03°00.27'N, 16°11.55'E, 420 m, 11-17.V.2001, YPT, lowland rainforest, CAR01-Y26, S. van Noort leg. (SAMC).

Diagnosis.

Female fully winged; head and mesosoma black, except mandible testaceous; head and scutum granulated and reticulate rugose; posterior surface of propodeum reticulate rugose, without longitudinal keels; forewing hyaline, without dark transverse bands or spots, with distal part of stigmal vein less than 0.5 as long as proximal part; segment 4 of protarsus slightly shorter than basal part of segment 5; segment 5 of protarsus (Figs 1A, 4D) with inner side curvilinear, with distinct apical region, basal part shorter than distal part, distal region very short and distal lamellae located near medial lamellae.

Description.

Female. Fully winged; length 2.2 mm. Head black, except mandible testaceous; antenna testaceous, except dorsal side of segments 6-10 brownish; metasoma brown; legs testaceous. Antenna clavate; antennal segments in following proportions: 10:5:6:5:4:5:6:5.5:5.5:7. Head dull, granulated and reticulate rugose; frontal line complete; face without two lateral keels around orbits and directed towards antennal toruli; occipital carina complete; POL = 6; OL = 3; OOL = 3: OPL = 4; TL = 4; greatest breadth of posterior ocelli about as long as OL. Pronotum dull, reticulate rugose; posterior surface longer than OPL (7:4) and shorter than scutum (7:14); pronotal tubercle reaching tegula. Scutum dull, granulated and reticulate rugose, except short unsculptured area near anterior margin. Notauli incomplete, reaching about 0.3 length of scutum. Scutellum and metanotum shiny, punctate, unsculptured among punctures. Mesopleuron and metapleuron dull, reticulate rugose. Propodeum dull, with transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (2.5:9). Protarsal segments in following proportions: 5:2:3:4:13; segment 2 of protarsus produced into hook. Segment 4 of protarsus slightly shorter than basal part of segment 5 (4:6). Segment 5 of protarsus (Figs 1A, 4D) with basal part slightly shorter than distal part (6:7), with inner side curvilinear and with apical region distinct. Enlarged claw (Figs 1A, 4D) with proximal prominence bearing one long bristle. Segment 5 of protarsus (Figs 1A, 4D) with one row of 16 lamellae; distal apex with 6 lamellae. Tibial spurs 1/1/2.

Male. Unknown.

Differential diagnosis.

Because of the above diagnosis, the new species is similar to Anteon canabense (Benoit, 1951b). The main differences regard the sculpture of the posterior surface of the propodeum and the colour (posterior surface of propodeum granulated, except few irregular keels near margins; head and mesosoma testaceous-reddish, occasionally partly darkened, in Anteon canabense ; posterior surface of propodeum reticulate rugose; head and mesosoma black, except mandible testaceous, in Anteon dzanganum ).

Etymology.

The species is named after the type locality, Dzanga-Ndoki National Park.
