Description Male. Body length 4.5 mm . Forewing 2.6 mm . Head: head as long as wide. Malar space shorter than VOL, convergent anteriorly. Mandible with three sharpened apical teeth. Median clypeal lobe rounded; lateral lobe short; median clypeal carina arched, complete, straight in dorsal view. Antenna long [surpassing the mesoscutum]; scape slightly curved; pedicel caliciform; flagellomere I longer than pedicel; flagellomeres long. Eye small [0.5 x LH], circular. Frons strongly foveolate. Frontal angle of ocellar triangle 90° ocelli small, DAO 1.0 × POL; ocellar fovea present. Dorsal half of occipital carina high, with side strigate; ventral half of occipital carina complete, high, with side strigate. Mesosoma: dorsal pronotal area shorter than wide, foveolate, anterior margin outcurved, anterior corner angled, trapezoidal, lateral margin slightly incurved, posterior margin incurved; longitudinal pronotal sulcus complete. Anteromesoscutum weakly foveolate, longer than mesoscutellum; longitudinal antero-mesoscutal sulcus incomplete, with anterior half with median carina; notaulus deep, wide, polished; parapsidal signum shallow. Axilla polished, shallow. Mesoscutum-mesoscutellar sulcus arched, not laterally dilated; mesoscutellum medium, foveolate. Metapectal-propodeal complex 0.5 × as long as wide; metapostnotum without longitudinal ridge between metaposnotal median carina and metaposnotal-propodeal suture; metapostnotal surface areolate; metapostnotal median carina complete; posterior projection of metapectal-propodeal complex long, narrow. Propodeal declivity strigate, with median and lateral carinae. Lateral surface of metapectal-propodeal complex areolate, with subdorsal and vertical carinae. Mesopleuron foveolate; posterior oblique sulcus foveolate; mesopleural suture with inner margin strigate. Wings: macropterous; transverse median vein bi-angulate; stigma sub-developed, distal margin truncate. Metasoma: tergum I with ventral surface strigate, with lateral pilosity; tergum II with dorsal surface punctured, with lateral pilosity, ventral surface punctured. Hypopygium with short anterior spiculum wide. Genitalia: paramere apex densely setose; ventral arm of paramere short, club-shaped; dorsal arm of paramere shorter than ventral one, filamentary with apex swollen. Cuspis ventral arm aligned with dorsal arm apex, slender; dorsal arm slender. Aedeagus slender, with apex surpassing paramere apex, Figure 2. Habitus. A. I. sauvignonblanc sp. nov . ; B. I. semillon sp. nov. apical margin angled, and apical sickle process short, lateral of margin of basal portion slightly outcurved. Colouration. Wings: bi-banded; orange: pronotum and mesonotum; castaneous: flagellum, palpi, and tarsi; dark castaneous: scape, pedicel, mandible, tegula, wing venation, coxae, trochanters, femora, tibiae, and metasoma; dark castaneous nearly black: head and metapectal-propodeal complex. Remarks This species is similar to I. saintjohni ( Móczár, 1977 ) in having the head and metapectalpropodeal complex dark castaneous nearly black and the pronotum and mesonotum orange, head as long as wide, eye small, the posterior projection of metapectal-propodeal complex long, and lateral surface of metapectal-propodeal complex areolate, with metapectal and posterior carinae. That is the same pattern of variation found between I. saintjohni and I. pinotnoir sp. nov. Indeed, I. sauvignonblanc sp. nov. is very similar to I. pinotnoir sp. nov. by having the flagellum light castaneous, median clypeal lobe rounded, longitudinal sulcus of anteromesoscutum incomplete or absent, hypopygium with speculum wide, paramere dorsal arm filamentary and swollen apically, and aedeagus with apical sickle process short. As cited above for I. pinotnoir sp. nov. , this species also has the anterior half of longitudinal sulcus of anteromesoscutum with median carina, a distinct characteristic shared by these two species. Distribution Kenya , Botswana , and South Africa . Etymology. The specific epithet sauvignonblanc , a noun in aposition, in allusion to Sauvignon Blanc grapes, one of the most cultivated wine grapes in Africa.
