Diagnosis
This species comes near Epitranus crassicornis Bouček in the key to species by Bouček (1982)[1] and Narendran (1989)[3], but differs from it in having: 1) malar space setose (malar space with very few setae in Epitranus crassicornis); 2) antenna not unusually short (in Epitranus crassicornis antenna unusually short and stout, pedicel and flagellum combined only 1.1 × width of head), and 3) mesosoma usually black (in Epitranus crassicornis mesosoma red).
Description
♀♂, length of body 2.4–4.9 mm.
Colour. Body mostly black with reddish colour on legs beyond coxae and at least ventrally on metasoma.
Head. Scrobal area flat with cross striae merging with reticulations; antenna extremely variable in length. In ♀ combined length of pedicel and flagellum 1.0–1.2 × as long as wide; T7 1.3 × as long as broad, scape in ♀ 0.8–1.2 × as long as width of vertex, usually reaching lower margin of anterior ocellus but sometimes shorter. In ♂ flagellum 1.3–2.6 × breadth of head; F1 2.0–3.4 × as long as broad and 0.4–0.8 × length of scape.
Mesosoma. Punctures on pronotum and mesoscutum close, with interstices narrower than diameter of a puncture, mostly smooth, occasionally rugulose; punctures on scutellum deeper than punctures of mesoscutum, interstices smooth and shiny.
Wings. Fore wing 2.8–3.0 × as long as broad, pilosity fairly extensive including a distinct line of setae from the end of fore wing venation to the base of wing and a hair line ventrally of costal cell.
Legs. Hind coxa twice as long as wide, outer ventral margin with 7–12 teeth; hind tibia with subbasal hump often indistinct or indicated by suberect setae and concealed small denticles; tarsal sulcus usually confined to one-third above basal insertion.
Metasoma. Petiole in ♀ 3.8–5.6 x, in ♂ 4.6–6.8 × as long as broad. Petiole shorter than metasoma in both sexes, 0.6–0.7 × length of metasoma.
Variation
Bouček (1982)[1] stated that “extreme forms are connected by numerous transitional forms”.
Host
Corcyra cephalonica Stainton (Lepidoptera: Pyralidae) in rice storage in Kerala (India).
Distribution
India, Nepal, Sri Lanka, Vietnam (Dai Lanh, Bian; Bam Me Thuot; Dalat), Thailand, Laos, Malaysia, Indonesia, Philippines, China (Taiwan), Japan (Bouček 1982[1]; Narendran 1989[3]).
