28. Anteon nkubayei sp. nov. *

( Fig. 2A )

Type material. HOLOTYPE: J, BURUNDI: Rusizi National Park , 3.34364°S 29.27246°E, 774 m, 13–20.iv.2010, Malaise trap near three small trees, degraded bush/grassland, R. Copeland leg. ( MRAC).

Diagnosis. Male with head and scutum granulated and reticulate rugose; OPL about as long as OOL; propodeum provided of strong transverse keel between dorsal and posterior surface; posterior surface of propodeum not provided with longitudinal keels; paramere about as long as penis, without distal inner pointed or rounded process ( Fig. 2A ).

Description. Male. Fully winged; length 2.5 mm. Head black, except mandible testaceous; antenna testaceous; mesosoma black; metasoma brown; legs testaceous, except proximal extremity of metacoxa darkened. Antenna filiform; antennal segments in following proportions: 11: 7: 5: 5: 5: 6: 6: 7: 7: 10. Head dull, completely granulated and reticulate rugose; frontal line complete; face with two lateral keels directed towards antennal toruli; occipital carina complete; POL = 9; OL = 4; OOL = 5; OPL = 5; TL = 5; greatest breadth of posterior ocellus shorter than OPL (3: 5). Scutum dull, completely strongly granulated and reticulate rugose, with tracks of notauli reaching about 0.5 length of scutum. Scutellum and metanotum shiny, smooth, punctate, without sculpture among punctures. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose, dull; posterior surface dull, reticulate rugose, without longitudinal keels, with areolae much smaller than those of dorsal surface. Forewing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (2: 8). Paramere ( Fig. 2A ) without distal inner pointed process. Tibial spurs 1/1/2.

Female. Unknown.

Differential diagnosis. With reference to the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Anteon harinhalai Olmi, 2010 , known from Madagascar, but it differs in the ratio OPL/OOL (head with OPL about 0.5 as long as OOL in A. harinhalai, OPL about as long as OOL in A. nkubayei ). In addition, the notauli are absent in A. nkubayei , incomplete and reaching about 0.5 length of scutum in A. harinhalai .

Hosts. Unknown.

Etymology. This species is named after Evariste Nkubaye of the Institut des Sciences Agronomique du Burundi who helped greatly with our collecting of Dryinidae and other insects.

Distribution. Only known from the type locality.
