Afrobethylus swazi Ramos & Azevedo , sp. nov.

( Figs 5 A–D)

Description. Holotype. Female. Body length 3.86 mm; forewing 2.59 mm long. Colour. Head dark castaneous, mandible dark castaneous. Mesosoma dark castaneous. Metasoma dark castaneous.

Head. In profile subrectangular, almost glabrous, 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 inconspicuous. Antenna 0.93 mm; flagellar pubescence sparse; with few outstanding erect setae. First five antennal segments in ratio of about 6:3:3:3:3. Eye not gibbous, large, glabrous, 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 absent. Hypostomal carina straight.

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

Wings. Forewing with distal margin of 2R1 cell not forming right angle; RS+M vein absent; Flexion lines not forming rectangular area, when is present only one longitudinal flexion line. Hind wing with three distal hamuli, adjacent.

Metasoma. 1.9 × 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 strongly projected; 2vv shorter than 1vv; iva long, wide; pp2vf long, narrow.

Male. Unknown.

Material examined. Holotype ♀. SOUTH AFRICA, Kawazulu-Natal, Coleford Natural Reserve (18.6 km 212º SW Underberg), 29º57.393'S 29º27.155'E, 8–11.xii.2001, Malaise trap UN01-SR1-M52, S. van Noort, Moist Upland Grassland on sandstone, SAM-HYM A026923 ( ISAM).

Distribution. South Africa.

Remarks. This species is similar to A. bapedi sp. nov. by having the area between anterior margin of eye and demarcation of median clypeal lobe clearly concave, the vertex crest straight, and with thick setae absent, the mesoscutellum extending beyond anterior margin of metapostnotum, and the forewing with flexion lines not forming a rectangular area. However this species has the forewing with 2R1 cell not forming a right angle, and the genitalia with the sting only slightly longer than the body of genitalia, whereas A. bapedi sp. nov. has the forewing with 2R1 cell forming a right angle, and the female the sting as long as the body of genitalia.
