( Fig. 1 View FIGURE 1 )
Material examined. Holotype: female, KENYA, Western Province , Malava Forest, 1619 m, 0.46372° N, 34.85727° E, Malaise trap in indigenous forest, 4–18.v.2017, leg. R. Copeland (Deposited in: ICIPE) GoogleMaps . Paratypes: female, same locality as holotype, 1–15.vi.2017 (Deposited in: SIZK); female, Western Province, Kakamega Forest , nr. KFS HDQTRs, 1620 m, 0.23742° N, 34.86607° E Malaise trap in indigenous forest, 19.iv–2.v.2017, leg. R GoogleMaps . Copeland (Deposited in: ICIPE).
Diagnosis. Gnathochorisis malavensis sp. n. is characterized by the combination of the following characters: fore wing with areolet closed (vein 3 rs-m present), face, meso- and metapleuron, and second metasomal tergite black, second tergite distinctly granulate except apex, third tergite smooth, unsculptured, propodeum smooth, unsculptured.
Description. Holotype. Female ( Fig. 1 View FIGURE 1 ). Body length approximately 2.7 mm, fore wing 2.0 mm.
Head ( Fig. 1B View FIGURE 1 ) generally smooth and sparsely pubescent. Antenna with 18 flagellomeres, first flagellomere 1.3 × the length of the second, flagellomeres; maximum diameter of lateral ocellus 0.8 times × the length of the ocellar-ocular distance; inner margins of eyes diverging downwards; face about 0.7 × as long as wide, smooth, weakly granulate centrally, covered with long setae; clypeus moderately convex, about 0.4 × as long as wide, distinctly separated from face, notched apically, smooth, covered with long setae; malar space about as long as the basal width of mandible; subocular sulcus distinct; mandible narrow, weakly twisted, both teeth visible, upper tooth longer than lower tooth; occipital carina largely absent dorsally; temples strongly narrowed behind eyes, short.
Mesosoma ( Fig. 1C, D View FIGURE 1 ). Propleuron smooth, sparsely pubescent; pronotum smooth, epomia absent; mesoscutum weakly transverse, with notauli absent, densely pubescent; scutellum convex, smooth, sparsely pubescent, with lateral carina present basally; mesopleuron smooth, densely pubescent ventrally, epicnemial carina present on lower half of mesopleuron; metapleuron smooth, submetapleural carina strong, pleural carina present and complete; propodeum ( Fig. 1C View FIGURE 1 ) smooth and sparsely pubescent, with well-developed carinae, area basalis weakly defined apically, area superomedia fused with area apicalis. Legs stout, hind femur 3.2 × longer than wide; fifth tarsomere 1.4 × as long as third tarsomere. Fore wing with areolet closed (vein 3 rs-m present); vein cu-a opposite to Rs&M. Hind wing nervellus weakly inclivous, with distance between first abscissa of Cu and M weakly longer than vein cu-a.
Metasoma ( Fig. 1E View FIGURE 1 ) generally smooth and impunctate. First tergite 2.5 × as long as apical width, granulate, dorsolateral carina distinct on basal 0.9 of the tergite, but weak, median longitudinal carina distinct and strong, reaching the apex of the tergite, glymma absent; second tergite 0.7 × as long as apical width, distinctly granulate except apex; third tergite smooth and unsculptured; ovipositor ( Fig. 1D View FIGURE 1 ) up-curved, the length from tip of hypopygium about 0.9 × length of hind tibia.
Colour. Body black. Scape, pedicel, first flagellomere, mandible (except apex), upper hind corner and lower angle of pronotum narrowly orange; legs generally yellowish-orange, except hind coxa partly, hind femur apically, hind tibia largely and tarsus entirely brown; pterostigma and veins brown, ovipositor orange.
Male. Unknown.
Variability. Second metasomal tergite vary from distinctly transverse to subquadrate. Hind legs in one paratype largely brown: coxa, femur and tarsus entirely and tibia except base.
Distribution. Currently known only from Kenya.
Etymology. This species is named after the type locality, Malava forest.
