Pediobius marjoriae Kerrich, 1973: 131  –132.

Diagnosis (female). Head in dorsal view about 3.0× as broad as long ( Fig. 5C, F View Figure ), face smooth, frons medially flat, with distinct frontal and scrobal sutures, lower face slightly narrowed ( Fig. 5B View Figure ): malar space about 0.5× as long as eye height; mouth opening slightly wider than malar space; antennal toruli situated at about level of lower eye margins, mandible with two teeth; occipital margin sharp and weakly curved; antennal scape pale, legs pale brown; mesoscutum and mesoscutellum with light sculpture ( Fig. 5C, F View Figure ), notauli indistinct, present as shallow depressions; mesoscutellum with one pair of setae; propodeum with distinct nucha bearing two shallow foveae, its submedian areas almost about 1.5× as broad as long, submedian carinae diverge posteriorly; propodeal callus with 3 setae; metatibial spur about 0.8× as long as metabasitarsus, about 2.0× as long as breadth of metatibia; subcosta of submarginal vein with 2 bristles; forewing speculum closed ( Fig. 5D View Figure ); fore wing transparent; WIP with narrow violet field along apical margin and wide blue field behind it ( Fig. 5E View Figure ); metasomal petiole transverse, about 1/2–1/3 as long as propodeum; gaster lanceolate ( Fig. 5A View Figure ), 1.8–2.4× as long as broad, Gt1 occupying approximately 1/2 of length of gaster.

Type material. Holotype ♀, Uganda, Moniko, T. 754, vii.1941, T.H.C. Taylor, BMNH. HYM 5.2236 (deposited in: BMNH)  . Paratypes 10 ♀, ibid. ( BMNH). 

Other material studied. ♀, DRC, “ Congo Belge: P.N.A. 7–15-VII-1955, P. Vanschuytbroeck, 13274-309, Mont Hoyo, 1.280 m, sur plantes basses” ( RMCAAbout RMCA).

Distribution. Uganda (Kerrich 1973), DRC (new record).

Host. Kerrich (1973) mentioned that the type series of this species was reared from pupae of a Lepisiota  ant: “ex cocoon of ant (? Acantholepis  sp.)”. However, there are no host records on any of the labels of the type specimens. It is likely that the information about the host association derived from T. H. C. Taylor's record coded as "T.754", which was not mentioned in the original description, but is present on a separate label of each specimen of the type series.

Comparative remarks. The species was described by Kerrich (1973) from a series of females reared from ant cocoons in Uganda. The original description mentions the holotype and 11 paratypes, whereas the BMNH collection houses the holotype and 10 paratypes. The species resembles P. rohombaya  (see below), but differs by the flat frons ( Fig. 5A, B, F View Figure ) (convex in P. rohombaya  , Figs 6A View Figure , 17H View Figure ), closed forewing speculum ( Fig. 5D View Figure ) (open in P. rohombaya  , Fig. 6F View Figure ) and inconspicuous notauli ( Fig. 5F View Figure ) (distinct in P. rohombaya  , Fig. 6A View Figure ).
