Anteon semajanna Olmi, Copeland & Guglielmino 2015: 349 ; Olmi et al. 2016: 68 .

Description. ♂ ( Figs 72 C–F). Fully winged; body length 1.2–2.3 mm. Head black, except mandible testaceous; an- tenna testaceous; mesosoma black; metasoma brown; legs testaceous. Antenna filiform; antennomeres in following proportions: 8:4:4:4:4:5:5:5:5:7. Head granulate and reticulate rugose (rugosity hardly visible); frontal line complete; frons with two hardly visible lateral keels along orbits directed towards antennal toruli; occipital carina complete; POL = 5; OL = 3; OOL = 3.5; OPL = 2.5; TL = 2.5; greatest breadth of posterior ocellus slightly shorter than OPL (2:2.5). Mesoscutum shiny, alutaceous, with lateral regions and occasionally median region granulate; area near anterior margin rugose. In specimen from Kenya, 2.07846°S 38.22530°E, mesoscutum punctate, unsculptured among punctures, rugose near anterior margin. Notauli incomplete, reaching about 0.4 × length of mesoscutum (in specimen from Uganda, 0°33.871’S 30°21.355’E, notauli invisible among areolae located near anterior margin of mesoscutum; in specimen from Kenya, 2.07846°S 38.22530°E, notauli incomplete, reaching about 0.25 × length of mesoscutum). Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc completely reticulate rugose, with strong transverse posterior keel; propodeal declivity without longitudinal keels, with areolae less wide than those of metapectal-propodeal disc. Forewing hyaline, without dark transverse bands or spots; distal part of 2rrs&Rs vein much shorter than proximal part (2:6). Paramere ( Fig. 69E ) with distal inner pointed process; proximal membranous process long, with mosaic sculpture and many sensorial setae. Tibial spurs 1/1/2.

♀. Unknown.

Hosts. Unknown.

Distribution. Central African Republic, Kenya, South Africa, Uganda.

Remarks. There is only a single morphological difference between A. semajanna and A. whartoni Olmi 2011 : in A. semajanna , the propodeal declivity does not have longitudinal keels; A. whartoni has two longitudinal keels or only one keel on the left. It is possible that the two species are conspecific.
