Type material.

HOLOTYPE: ♀, UGANDA: WESTERN REGION: Kibale National Park, Kanyawara, Makerere University Biological Field Station, 0°33.836'N, 30°21.700'E, 1523 m, 4-26.VIII.2008, UG08-KF8-Y07, YPT, primary mid-altitude rainforest, S. van Noort leg., 1♀ (SAMC).

Diagnosis.

Female with head black, except mandible and clypeus testaceous; head flat, with posterior margin of vertex convex and TL more than twice as long as POL; head (dorsally viewed) provided with posterior ocelli placed behind imaginary straight line joining posterior edges of eyes; posterior ocelli almost touching occipital carina; head and scutum granulated and reticulate rugose, not sculptured by longitudinal keels or striae; pronotum black, except posterior collar ferruginous; posterior collar of pronotum present; propodeum black; segment 1 of protarsus slightly longer than segment 4; enlarged claw (Figs 2B, 11F) approximately as long as segment 5 of protarsus.

Description.

Female. Fully winged; length 7.3 mm. Head black, except mandible and clypeus testaceous; antenna brown, except segments 1-2 and 10 testaceous, distal extremity of segment 4 and proximal third of segment 5 whitish; propleuron brown-black; pronotum black, except posterior collar ferruginous; rest of mesosoma black; metasoma brown-testaceous; legs testaceous. Antenna clavate; antennal segments in following proportions: 12:6:56:33:21:14:10:7:8:10; rhinaria present in segments 6-10. Head dull, granulated and reticulate rugose, without longitudinal keels; occipital carina complete; posterior ocelli almost touching occipital carina, situated just behind virtual straight line joining posterior edges of eyes; POL = 2; OL = 1.5; OOL = 12; OPL = 0.3; TL = 6; greatest breadth of posterior ocelli longer than POL (3:2). Pronotum dull, granulated, with numerous keels around disc, on lateral regions and anterior collar; pronotum crossed by slight anterior transverse impresion and strong posterior transverse furrow; anterior collar little distinct; posterior collar long; pronotal tubercle not reaching tegula. Scutum granulated and reticulate rugose, not sculptured by longitudinal keels. Notauli incomplete, reaching about 0.8 length of scutum. Scutellum granulated, weakly rugose. Metanotum rugose. Propodeum reticulate rugose, without longitudinal keels on posterior surface; dorsal surface much longer than posterior surface. Forewing with two dark transverse bands; distal part of stigmal vein much longer than proximal part (22:8). Protarsal segments in following proportions: 27:5:9:26:41. Segment 3 of protarsus produced into hook. Enlarged claw (Figs 2B, 11F) with one large subdistal tooth and one row of 13 lamellae. Segment 5 of protarsus (Figs 2B, 11F) with two rows of about 48 lamellae; distal apex with approximately 40 lamellae. Tibial spurs 1/1/2.

Male. Unknown.

Differential diagnosis.

Because of the above diagnosis, the new species is similar to Dryinus undulatus (Benoit, 1950b). The main difference regards the sculpture of the head and scutum: granulated and reticulate rugose, not sculptured by longitudinal keels or striae, in Dryinus kibalus ; head granulated and with some longitudinal keels and scutum granulated and sculptured by many subparallel longitudinal keels in Dryinus undulatus .

Etymology.

The species is named after the type locality, Kibale National Park.
