Diagnosis. Male with clypeus not sculptured by longitudinal and parallel keels; posterior surface of propodeum without longitudinal keels; distal apex of distal inner process of paramere located near distal apex of paramere ( Fig. 3A View Fig ); paramere with distal inner pointed process; dorsal membranous process of paramere with many sensorial setae ( Fig. 3A View Fig ).

Description. Male. Fully winged; length 1.2–2.3 mm (holotype 2.3 mm). Head black, except mandible testaceous; antenna testaceous; mesosoma black; metasoma brown; legs testaceous. Antenna filiform; antennal segments in following proportions: 8: 4: 4: 4: 4: 5: 5: 5: 5: 7. Head granulated and reticulate rugose (rugosity little visible); frontal line complete; face 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). Scutum shiny, alutaceous, with lateral regions and occasionally also median region of scutum granulated; area near anterior margin rugose. Notauli incomplete, reaching about 0.4 length of scutum. Scutellum and metanotum shiny, unsculptured. Propodeum completely reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels, with areolae smaller than those of the dorsal surface. Forewing hyaline, without dark transverse bands or spots; distal part of stigmal vein much shorter than proximal part (2: 6). Paramere ( Fig. 3A View Fig ) with distal inner pointed process; proximal membranous process long, with mosaic sculpture and many sensorial setae ( Fig. 3A View Fig ). 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 emeritum Olmi, 1984 . Both have male genitalia with long dorsal membranous process of paramere, but in A. semajanna this process has many sensorial setae ( Fig. 3A View Fig ) that are missing in A. emeritum ( Fig. 3B View Fig ). This character is very important in the systematics of Anteon males ( XU et al. 2013, OLMI & VIRLA 2014).

Etymology. This species is named after the son and daughter, James Quinn and Anna Leigh Taylor-Copeland of the collector (RSC) of the Kenyan types; semajanna joins their first names, spelled backwards.

Hosts. Unknown.

Distribution. Only known from Uganda and Kenya (Coast Province).
