Afrobethylus antankarana Ramos & Azevedo , sp. nov.

( Figs 2 View FIGURE 2 A–D)

Description. Holotype. Female. Body length 5.4 mm; forewing 3.14 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 stepshaped teeth. Clypeus with median lobe rounded, weakly projected; median carina absent, straight in profile; lateral lobe inconspicuous. Antenna 1.14 mm; flagellar pubescence sparse; with few outstanding erect setae. First five antennal segments in ratio of about 6:3:2:2:2. Eye not gibbous, large, glabrous, located more laterally, area between anterior margin of eye and demarcation of median clypeal lobe clearly concave. Frons coriaceous-punctate. Ocelli small; posterior ocelli close to vertex crest; ocellar triangle compact; anterior ocellus not surpassing imaginary top eye line. Vertex crest convex, thick setae absent. Hypostomal carina straight.

Mesosoma . Pronotal disc as long as wide, coriaceous-punctate; anterior corner angled; posterior margin concave. Parapsidal furrow conspicuous. Mesoscutellum not reaching anterior margin of metapostnotum. Metapectal-propodeal complex with metapleural carina conspicuous.

Wings. Forewing with distal margin of 2R1 cell 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, discontinuous.

Metasoma. 2.72 × as long as wide, polished, whole surface with few setae. Ventral carina of petiole present, incomplete.

Genitalia. Sting (1vv+2vv) as long as body of genitalia; Fu wide; 1vf with apex angled; d1vf large; dorsal ramus of 2vf with superior margin of anterior region rounded, anterior margin strongly projected; 2vv as long as to 1vv; iva long, narrow; pp2vf long, narrow.

Male. Unknown.

Distribution. Madagascar.

Remarks. This species is similar to A. antemoro sp. nov. by having the area between anterior margin of eye and demarcation of median clypeal lobe clearly concave, the clypeus with median clypeal lobe rounded, the ocelli small, the vertex crest convex, and with thick setae absent, the genitalia with sting as long as the body of genitalia. However this species has the clypeus with median carina absent, the pronotal disc as long as wide, the mesoscutellum not reaching anterior margin of metapostnotum, and the forewing with flexion lines not forming a rectangular area, whereas A. antemoro sp. nov. the clypeus with median carina present, the pronotal disc shorter than wide, the mesoscutellum reaching anterior margin of metapostnotum, and the forewing with flexion lines forming a rectangular area.
