Afrobethylus antemoro Ramos & Azevedo  , sp. nov.

( Figs 3View FIGURE 3 A –D)

Description. Holotype. Female. Body length 4.6 mm; forewing 3.4 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, projected; median carina present, arched in profile, extending far back into frons; lateral lobe inconspicuous. Antenna 1.1 mm; flagellar pubescence sparse; with few outstanding erect setae. First five antennal segments in ratio of about 8: 3: 3: 3: 3. 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 shorter than wide, coriaceous-punctate; anterior corner angled; posterior margin almost straight. Parapsidal furrow conspicuous. Mesoscutellum reaching anterior margin of metapostnotum. Metapectal-propodeal complex with metapleural carina conspicuous.

Wings. Forewing with distal margin of 2 R 1 cell forming right angle; RS+M vein absent; Flexion lines forming rectangular area, when delimited by three flexion lines. Hind wing with three distal hamuli, discontinuous.

Metasoma. 1.1 × as long as wide, polished, whole surface with few setae. Ventral carina of petiole absent.

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

Male. Unknown.

Material examined. Holotype ♀. MADAGASCAR, Province d'Antananarivo, Botanic Garden near the entrance to Andasibe National Park, 19 º 55.99 'S 48 º 24.49 'E, 1026 m, 1– 5 Sept[ember] 2001, Malaise trap tropical forest MA01–08B- 11, collector: R.

Fianarantsoa, 1 ♀, Parc National Ranomafana, radio tower at forest edge, 21 º 15.05 'S 47 º 24.43 'E, 1130 m, 15–21 December 2001, Malaise trap, mixed tropical forest MA-02–09B-07, collector: R. Harin'Hala CASENT 2063426 ( CASC); 1 ♀, Ranomafana, JIRAMA water works, 21 º 14.91 'S 47 º 27.13 'E, 690 m, 21–24 December 2001, Malaise trap near river MA-02–09D-08, collector: R. Harin'Hala, CASENT 2088677 ( CASC).

Distribution. Madagascar.

Variation. Body length 3.66 –4.0 mm; forewing 2.83 –3.0 mm long; the head with median carina of clypeus extending back into frons up to anterior margin of eye.

Remarks. This species is similar to A. antankarana  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 female genitalia with sting as long as the body of genitalia. However this species has 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, whereas A. antankarana  sp. nov. 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.
