Holotype ♀ in MHNG, here designated, labelled ‘ MALI Sikasso ex stock de mil 1 X 1986 [print, blue label]; B. Sauphanor leg. 6241 [print, blue label]; 2119 Baur [print]; Holotype ♀ Anisopteromalus cornis sp. n. Baur lab. H. Baur 2014 [hand, label with red left and right border]’ (entire; glued on card rectangle with metasoma detached from rest of body); type locality: MALI: Sikasso (examined by Baur).

Diagnosis, female. Head and mesosoma blue-green with bronze tinge in places, setae whitish, conspicuous ( Fig. 5 L).

Gena terete, not carinate near mouth margin. Flagellum filiform ( Fig. 5 J), first funicular segment subconical, basally about as broad as third anellus, provided with 1–2 rows of longitudinal sensilla. Scutellum projecting at level of anterior margin of dorsellum, in lateral view weakly curved. Forewing with setae on wing disc dark. Speculum bare, open below but sometimes closed in proximal part. Anterior plica of propodeum short and evenly curved, joining an indistinct costula. Posterior margin of first gastral tergite curving backwards and strongly produced. Head breadth 1.15–1.26× metatibia length and 1.37–1.40× eye distance; head height 3.15–3.59× eye breadth; eye height 1.05–1.09× scutellum length; pedicel plus flagellum 2.43–2.69× eye height; mesosoma length 6.19–7.96× OOL; scutellum length 1.64–1.74× stigmal vein; metatibia length 1.90–2.29× marginal vein; gaster length 7.98–11.94× OOL.

Description, female. Antenna with scape testaceous, pedicel fuscous on upper side, anelli fuscous and rest of flagellum testaceous, fuscous on upper side. Legs with tibiae yellowish.

Head 0.98–1.14× as broad as mesoscutum. POL 1.33–1.64× OOL. Eyes 1.65–1.87× as high as broad, separated by 1.53–1.64× their height. Malar space 0.59–0.74× eye height. Head in frontal view 1.09–1.19× as broad as high. Antenna with scape 1.05–1.10× as long as eye height. Combined length of pedicel plus flagellum 1.06–1.26× head breadth. First and second anellus strongly transverse, third conspicuous, slightly longer than second anellus.

Mesosoma 1.20–1.30× as long as broad. Mesoscutum 1.92–2.16× as broad as long. Hind margin of scutellum broadly rounded. Upper mesepimeron strongly narrowing below, reaching at most basal third of mesopleuron. Basal setal line complete. Costal cell with dorsal surface with a short row of setae distally, lower surface with a patch of setae in distal half and a single row of setae running to proximal part, costal setal line complete. Forewing disc moderately pilose. Marginal vein 1.41–1.78× as long as stigmal vein. Stigma subcircular to slightly elongate, small. Propodeum 0.51–0.57× as long as scutellum. Median carina fine, straight. Median area in anterior part evenly reticulate with inner corner of anterior plica with a rather deep and reticulate depression along the anterior plicae. Nucha subglobose, not distinctly separated from rest of propodeum, alutaceous.

Metasoma: Gaster 1.71–2.89× as long as broad, 1.29–1.50× as long as mesosoma, and 0.63–1.05× as long as mesoscutum. Posterior margin of second gastral tergite weakly incised medially. Posterior margin of third gastral tergite straight.

Etymology. The specific name ‘cornis’ is derived from Latin and means ‘horned’. It refers to the relatively long antennae.

Material examined. Beside the above-mentioned holotype we examined the following specimens: Paratypes, GHANA: 1♂, 1♀, East Gonja District, Salaga, 1944 ( G.S. Cottérell), ex moth borer on millet seeds ( BMNH); MALI: 7♂, 3♀, Sikasso Province, Sikasso, x.1986 (B. Sauphanor), ex host on stock millet ( CBGP; MHNG; NMBE); NIGERIA: 1♂, 1♀, Kaduna State, Zaria, Samaru, ex Sitotroga sp., 20.iii.1958 ( BMNH).

Biology. Reared from Sitotroga sp. (Lepidoptera: Gelechiidae).

Distribution. Afrotropical region.

Remarks. The species is very close in habitus to A. calandrae from which it can be most easily separated by its relatively long flagellum.
