( Figs 7 A–D)

Description. Holotype. Female. Body length 5.14 mm; forewing 2.96 mm long. Colour. Head dark castaneous, mandible dark castaneous. Mesosoma dark castaneous. Metasoma dark castaneous.

Head. In profile subtriangular, with many setae, dorsal view longer than wide. Mandible with apical combshaped teeth. Clypeus with median lobe angled, projected; median carina present, arched in profile, extending far back into frons; lateral lobe conspicuous. Antenna 1.48 mm; flagellar pubescence sparse; with few outstanding erect setae. First five antennal segments in ratio of about 7:2:3:3:3. Eye not gibbous, large, with sparse pilosity, located more laterally, area between anterior margin of eye and demarcation of median clypeal lobe almost straight. Frons coriaceous-punctate. Ocelli small; posterior ocelli close to vertex crest; ocellar triangle compact; anterior ocellus not surpassing imaginary top eye line. Vertex crest straight, thick setae present. Hypostomal carina straight.

Mesosoma . Pronotal disc shorter than wide, coriaceous-punctate; anterior corner angled; posterior margin sinuous. Parapsidal furrow inconspicuous. Mesoscutellum extending beyond anterior margin of metapostnotum. Metapectal-propodeal complex with metapleural carina inconspicuous.

Wings. Forewing with distal margin of 2R1 cell forming right angle; RS+M vein very short, represented by no more than angulate projection almost imperceptible arising from 1Rs vein; Flexion lines not forming rectangular area, when is present only one longitudinal flexion line. Hind wing with four distal hamuli, discontinuous.

Metasoma. 2.13 × as long as wide, polished, whole surface with few setae. Ventral carina of petiole present, incomplete.

Genitalia. Sting (1vv+2vv) longer than body of genitalia; Fu wide; 1vf with apex angled; d1vf large; dorsal ramus of 2vf with superior margin of anterior region angled, anterior margin weakly projected; 2vv shorter than 1vv; iva long, narrow; pp2vf short, wide.

Male. Unknown.

Distribution. South Africa.

Variation. Body length 3.33–4.33 mm; forewing 2.33–2.66 mm long; eye with few setae; vertex crest with few thick setae.

Remarks. This species is very different of the others by having the head with eye with many setae, the genitalia with pp2vf of the 2vf short, and wide.
