Colour. Body brown to black, abdomen brown at apex; mandible, teeth dark brown; antenna yellow, terminal final segments light brown; coxae, femora light brown, other segments yellow, wing hyaline; prostigma, pterostigma, costa, subcosta light brown, other veins straw coloured.
Head. Head distinctly longer than wide, WH 0.85 × LH; 1.72 × as long as wide in lateral aspect; frons and vertex strongly coriaceous, with scattered shallow punctures (Fig. 2 C); gena smooth and polished; vestiture moderately long, 0.06 mm; profuse, decumbent; setae on vertex distinctly longer than setae on head, longest being 0.15 mm; anterior clypeal margin strongly produced, bluntly angulated, acute; clypeal carina 0.73 × HE, strong, arcuate in profile, extending onto front as low carina slightly beyond posterior scrobal margin; scrobe carinate; mandible stout with four short, blunt teeth, ventral most straight and longest; WF 0.48x LH; WF = HE; EV 0.5 × HE; LH 1.74 × HE; malar space distinct; malar groove present; eye sparsely setose, setae minute, as long as diameter of single facet; ocelli in obtuse triangle; posterior ocelli contiguous with vertex margin; OOL 1.09 × WOT; POL: AOL: DAO = 4:2:2; vertex straight in full dorsal view, acutely, smoothly curving to occiput, ecarinate; relative lengths of first five antennal segments in ratio of about 7:3.5:2.5:3:3; scape 1.4 × as long as wide, 2 × as long as pedicel; pedicel longer than F1; F1 segment as long as wide; F2–F7 wider than long; F8–F9 as long wide; F10–F11 longer than wide; antenna slightly shorter than head in full dorsal view (25:27) (Fig. 2 C).
Mesosoma. Pronotum, mesonotum, and scutellum strongly coriaceous uniformly (Fig. 2 D); vestiture long, profuse, decumbent; sparse on scutellum, mesonotum; pronotal disc 0.55 × as long as wide; mesonotum with complete parapsidal furrow (Fig. 2 D); notauli absent; scutellum with a pair of slits at base connected by one weak narrow groove; propodeal disc 0.55 × as long as wide, smoothly inclined to lateral margin; basal median smooth triangle absent; median smooth longitudinal band not elevated, extending to posterior margin of propodeal disc, wider in posterior half; rest of propodeal disc and declivity strongly coriaceous; transverse propodeal carina medially interrupted broadly (Fig. 2 D); forewing 2.8 × as long as wide; areolet present, subtriangular in shape (Fig. 2 F); vein M, SM profusely setose, areolet sparsely setose; speculum profusely setose; profemur 1.92 × as long as wide; SI 10.74.
Metasoma. Tergites completely smooth and polished (Fig. 2 E); T1–T3 with few setae restricted to lateral margin; other tergites sparsely setose all across dorsal side; metasoma distinctly longer than mesosoma, shorter than head plus mesosoma (Fig. 2 A).
Male. Unknown.
Ecology and Biology. Ex. leaf galls on Memecylon umbellatum Burm. f. (Melastomaceae) induced by Crotonothrips sp. (Fig. 3 A) (Raman & Ananthakrishnan 1985); associate host: Carpelimus sp. (Staphylinidae) (Fig. 3 B).
Etymology. The species epithet is after the Latin word inauditus meaning new.
Variation. See table 1 for the morphometric ratios of the type materials examined.
Distribution. India (Karnataka; Kerala).
Discussion. Goniozus inauditus Santhosh sp. nov. comes close to G. nephantidis (Muesebeck), but differ in having ocular setae as long as diameter of single facet, scape 2 × pedicel, WF = HE, EV 0.62 × HE, mandible black brown and antenna shorter than head in full dorsal view (Fig. 2 C), whereas in G. nephantidis ocular setae 2 × as long as diameter of single facet, scape longer than 2 × pedicel, WF 1.15–1.20 × HE, EV 0.36–0.47 × HE, mandible black and antenna longer than head in full dorsal view.
