11. Anteon blacki sp. nov. *

( Figs 2B )

Type material. HOLOTYPE: J, KENYA: EASTERN: Nyambene Hills , Itieni Forest, at bottom, 0.24433°N 37.87016°E, 2142 m, 27.xi–11.xii.2011, Malaise trap, edge of indigenous forest, near forest station, R. Copeland leg. ( NMKE).

Diagnosis. Male with head reticulate rugose and granulated; scutum rugose; posterior surface of propodeum without longitudinal keels; paramere ( Fig. 2B ) with one large distal inner process showing many transverse folds; distal apex of distal inner process of paramere situated far from distal apex of paramere ( Fig. 2B ).

Description. Male. Fully winged; length 2.4 mm. Head black, except distal half of mandible testaceous; antenna brown; mesosoma black; metasoma brown-black; legs brown. Antenna filiform; antennal segments in following proportions: 12: 7: 6: 7: 7: 7: 7: 7: 7: 10. Head dull, reticulate rugose and granulated; frontal line complete (irregular in front of anterior ocellus); occipital carina complete; POL = 5; OL = 3; OOL = 5; OPL = 2.5; TL = 4; greatest breadth of posterior ocellus about as long as OPL. Scutum shiny, irregularly rugose. Notauli incomplete, reaching about 0.3 length of scutum. Scutellum shiny, smooth, unsculptured. Metanotum rugose. Propodeum with transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface completely reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands or spots; distal part of stigmal vein much shorter than proximal part (3: 8). Paramere ( Fig. 2B ) with one large distal inner process showing many transverse folds. Tibial spurs 1/1/2.

Female. Unknown.

Differential diagnosis. Based on the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Anteon cautum Olmi, 1994b , A. inane Olmi, 2004 and A. maritimum ( Turner, 1928) . However, in A. blacki the scutum is completely rugose, whereas in the other three species it is completely granulated and not rugose. In addition, in A. blacki the inner distal process of the paramere shows many transverse folds ( Fig. 2B ) not present in the other three species.

Etymology. This species is named after my (RSC) oldest friend, Mr. Chester Black.

Hosts. Unknown.

Distribution. Only known in the type locality.
