4. Aphelopus sequeirai Olmi, Copeland & van Noort , sp. nov.

( Figs 13B , 14)

Diagnosis. ♂ of Aphelopus with head mostly black and mesoscutum completely black; notauli reaching approximately 0.6 × length of mesoscutum; basivolsella not fused with paramere, with lateral proximal process; distivolsella with very slender distal part ( Fig. 13B );

Description. ♂ (Fig. 14). Fully winged; body length 1.9 mm. Head (Fig. 14C) black, except mandible testa- ceous; clypeus whitish; antenna brown, except scape and pedicel testaceous; mesosoma black; metasoma brown; legs yellow-testaceous, except proximal half of metacoxa brown. Antenna filiform; antennomeres in following proportions: 5:5:6:6:6:6:6:6:6:7. Head dull, granulate; frontal line absent; occipital carina complete; POL = 7; OL = 4; OOL = 3; OPL = 2.5; TL = 4; greatest breadth of lateral ocelli shorter than OL (3:4); clypeus almost touching antennal toruli. Mesoscutum and mesoscutellum dull, granulate. Notauli incomplete, reaching about 0.6 × length of mesoscutum. Metanotum shiny, unsculptured. Metapectal-propodeal disc dull, reticulate rugose, with transverse posterior keel; propodeal declivity with two complete longitudinal keels. Forewing hyaline, without dark transverse bands; 2r-rs&Rs vein curvilinear, shorter than normal 2r-rs&Rs veins of Aphelopus species; pterostigma brown, as large as in other Aphelopus species. Basivolsella very narrow, with two distal bristles ( Fig. 13B ), with lateral proximal process; distivolsella very slender. Tibial spurs 1/1/2.

♀. Unknown.

Material examined. Type: ♂ holotype, NMK/INV/T-637: KENYA: Nairobi Prov. , ICIPE Campus, Kasarani, 1.22317°S 36.89653°E, 1600 m, 3–10.VI.2014, MT, near stream, meadow in degraded shrub-/grassland, R. Copeland leg. ( NMK) .

Hosts. Unknown.

Distribution. Kenya.

Etymology. This species is named after Mr. Glenn Sequeira, a friend and co-worker of RSC at ICIPE, where he cheerfully and expertly leads the Information Technology unit.

Remarks. This species can be confused with Crovettia species, because the clypeus is almost touching the antennal toruli and the 2r-rs&Rs vein is shorter than in Aphelopus. However, the 2r-rs&Rs vein is curvilinear (as in Aphelopus species, though it is shorter than normal) and the pterostigma is less large than in Crovettia species.
