Holotype : ♀ , Sri Lanka , not examined. Closterocerus insignis : Mൺඇං (1971): 591 (record); Hඎඌൺංඇ & KIJൺඇ (1986): 216 (checklist); BൺඅൺΚ*©ංඌIJඇൺඇ et al. (1986): 89 (record), TIJൺ*©ൾඃൺ & Hൺඒൺඍ (2004): 4 (biology). Diagnosis. Female . Length, 1.25 mm . Head with occiput bluish green; vertex and frons dark blue with greenish lustre around ocellar triangle; clypeus violet. Mesosoma with mesoscutum and scutellum largely bluish green with bluish reflection laterally; metanotum and propodeum dark violaceous or purple. Fore wing with dark venation. Hind wing hyaline. Legs with coxae and femora, hind trochanters, hind tibiae and first hind tarsal segments black; fore and middletrochanter smoky; fore and middle tibiae, with their tarsi and last three hind tarsal segments pale yellow. Metasoma dark violaceous or purple. Head with vertex and frons reticulate; clypeus faintly reticulate. Antenna compressed; scape triangular, dilated apically, 2.50× as long as broad, longer than pedicel, F1 and F2 combined; pedicel subquadrate, convex laterally; funicle segments broader than long with oval and elongate sensilla. Mesosoma densely punctate reticulate; middle lobe of mesoscutum and scutellum broad; scutellum with one pair of setae; metanotum and propodeum narrow. Fore wing 2× as long as broad with three infuscate bands. Hind wing 3.75× as long as broad. Metasoma round and oval with slight reticulation on T3–T5. Differential diagnosis. Closterocerus insignis comes close to C. scapiatus , but differs from the latter in the following characters: F2 at most 2× as broad as long; C2 relatively more transverse, at most 2× as broad as long; C3 flattened; fore wing with apical band narrow; gaster dark violaceous and purple. In C. scapiatus : F2 at least 1.5× as broad as long; C2 relatively less transverse, at most 1.5× as broad as long; C3 oblong; fore wing with apical band broad; gaster dark brown. Host. Oscinis theae Green, 1895 ( Diptera : Agromyzidae ) (Mൺඇං 1971). Distribution in India . Delhi , Karnataka , Kerala , Tamil Nadu (Nඈඒൾඌ 2021).
