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, 12-26.VIII.2008, UG08-KF8-M18, Malaise trap, primary mid-altitude rainforest, S. van Noort leg. (SAMC).

Diagnosis.

Male with OPL slightly longer than POL; antennal segment 6 less than twice as long as broad; scutum and scutellum completely reticulate rugose; notauli absent; posterior surface of propodeum with median area crossed by numerous transverse keels.

Description.

Male. Fully winged; length 2.9 mm. Head black, except mandible testaceous; antenna brown, except segments 1-2 ferruginous; mesosoma black; metasoma brown; legs brown, with articulations, tarsi and protibia testaceous. Antenna filiform; antennal segments in following proportions: 14:6:8:8:7:7:7:7:7:10; antennal segment 6 less than twice as long as broad (7:5). Head convex, dull, covered with short hairs, completely reticulate rugose; clypeus reticulate rugose; frontal line complete, with pointed protrusion between antennal toruli; occipital carina complete; POL = 5; OL = 3; OOL = 7; OPL = 7; TL = 7; greatest breadth of posterior ocelli shorter than POL (4:5). Scutum, scutellum and metanotum dull, completely reticulate rugose. Notauli absent. Mesopleuron dull, reticulate rugose. Metapleuron dull, sculptured by numerous strong transverse keels. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface dull, reticulate rugose; posterior surface of propodeum with two complete longitudinal keels, median area crossed by many transverse keels and lateral areas completely reticulate rugose. Forewing hyaline, without dark transverse bands; distal part of stigmal vein about as long as proximal part. Genitalia as in Figs 2A, 10F. Tibial spurs 1/1/2.

Female. Unknown.

Differential diagnosis.

Because of the above diagnosis, the new species is similar to Bocchus seyrigi (Benoit, 1954). The main differences regard OPL/POL ratio (OPL slightly longer than POL in Bocchus kibalensis ; OPL more than twice as long as POL in Bocchus seyrigi ) and the sculpture of the median area of posterior surface of propodeum (crossed by many transverse keels in Bocchus kibalensis ; partly unsculptured in Bocchus seyrigi ).

Etymology.

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