Description. Holotype female. Length of body 4.53 mm, fore wing 3.64 mm, ovipositor 1.28 mm.
Head. Antenna with 42 flagellomeres. First flagellomere 1.2 × longer than 2 nd and 3 rd. Width of head: width of face: height of eye = 2.5: 1: 1.6. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1: 2.1: 1.7. Face 1.3 × as wide as long medially, smooth, setose ( Fig. 1B View FIGURE 1 ), slightly convex in lateral view ( Fig. 1D View FIGURE 1 ). Clypeus rugose with sparse setosity laterally ( Fig. 1B View FIGURE 1 ). Inner margin of eyes emarginated ( Fig. 1B View FIGURE 1 ). Transverse diameter of eye 2.5 × as long as temple in dorsal view ( Fig. 1C View FIGURE 1 ). Frons with shallow medial longitudinal groove ( Fig. 1C View FIGURE 1 ). Vertex and temple shiny, smooth sparsely setose ( Fig. 1C View FIGURE 1 ). Occipital carina present, not pointed medially ( Figs 1C, D View FIGURE 1 ).
Mesosoma. Mesosoma 1.9 × longer than high. Mesoscutum smooth, setose, rugose medio-posteriorly, carinate marginally, with crenulated groove laterally ( Fig. 1F View FIGURE 1 ). Notauli complete, joined posteriorly ( Fig. 1F View FIGURE 1 ). Scutellar sulcus with midlongitudinal carina ( Fig. 1F View FIGURE 1 ). Scutellum smooth, sparsely setose with distinct lateral carina ( Fig. 1F View FIGURE 1 ). Mesopleuron smooth except anterior part irregularly rugose and sparsely setose with widely crenulated precoxal sulcus ( Fig. 1E View FIGURE 1 ). Epicnemial carina present ( Fig. 1E View FIGURE 1 ). Metapleuron rugose, smooth anterior half, sparsely setose ( Fig. 1E View FIGURE 1 ). Propodeum with short midlongitudinal carina anteriorly rest rugose without sublateral longitudinal carina ( Fig. 2A View FIGURE 2 ).
Wings. Fore wing ( Figs 2C, D View FIGURE 2 ). Lengths of fore wing veins r-rs: 3RSa: 3RSb = 1: 2.6: 4.2. Lengths of vein 2RS: 3RSa: rs-m = 2.4: 5: 1. Length of 1CUb 4.0 × 1CUa. Hind wing vein M+CU 1.6 × 1Ma+1Mb ( Fig. 2C View FIGURE 2 ).
Legs. Lengths of fore femur: fore tibia: fore tarsus = 1: 1.3: 1.5. Lengths of hind femur: hind tibia: hind tarsus = 1: 1.3: 1.3. Hind femur 4.7 × longer than maximum width. Claws without basal lobe.
Metasoma. Length of first tergite 2.0 × longer than its apical width. Second tergite 1.4 × as long as third tergite. Second and third tergites 1.2, 0.9 × as long as its apical width respectively. First tergite longitudinally striate with midlongitudinal carina, sparsely setose ( Fig. 2E View FIGURE 2 ). Second tergite longitudinally striate, sparsely setose ( Fig. 2F View FIGURE 2 ). Third tergite longitudinally striate, sparsely setose ( Fig. 2F View FIGURE 2 ). Remaining tergites largely unsclerotised. Ovipositor sheath sparsely setose. Ovipositor sheath approximately 1.1 × as long as hind femur ( Fig. 1A View FIGURE 1 ).
Colour. Body yellow except apex of mandibles, ocellar area, vertex medially and laterally, pronotum dorsolaterally, mesoscutum laterally, mesopleuron except medially, metapleuron posteriorly, propodeum postero-laterally, distal wing veins, fore tibia, hind femora, tarsal claws, first metasomal tergite anteriorly and antero-laterally, metasomal tergite 4–7, ovipositor sheath brown.
Male. Same as female.
Distribution. Kerala, India.
Host. Unknown.
Ecology. The specimens were collected in the afternoon from grass land including some shrubby patches of Strobilanthes plants.
Etymology. Species is named after the first record of the genus from the Indomalayan (=Oriental) region.
Comparative diagnosis. Kerevata orientalia comes close to the other new species, K. kethai and K. longi based on general body colouration. However, this new species can be differentiated from K. kethai and K. longi in having completely yellow face, (vs with brownish or blackish patch), propodeum without smooth area near to anterior midlongitudinal carina (vs with smooth lateral areas), length of first metasomal tergite 2.0 × as long as its apical width (vs more than 2.0 × as long as its apical width), hind femur 4.7 × longer than maximum width (vs more than 6.6–7.5 × longer than maximum width).
