Monstranusia brachyptera Hayat , sp. nov. ( Figs 18–23 ) Female. Holotype . Length, 1.11 mm Brachypterous form ( Fig. 18 ). Head yellow; vertex with a dark brown band behind each posterior ocellus, which meets with a brown band on each side of occipital foramen; frontovertex and face with two narrow brown to dark brown bands, each beginning above torulus and ending at posterior ocellus, and with a transverse band at posterior ocelli connecting these two longitudinal bands; from toruli to mouth margin and malar space dark brown ( Fig. 19 ); occiput on each side of foramen with a brown band that extends ventrally; temple with a narrow brown band continuing behind eye and extending ventrally to three-fifths eye height ( Fig. 18 ). Antenna brown, gradually becoming dark brown from F2 onwards, with only third segment of clava white in about apical half. Mesosoma dark brown, medially with a narrow, white longitudinal band from apex of pronotum to near apex of scutellum ( Fig. 20 ), interrupted by a brown transverse band at level of scuto-scutellar suture; scutellum with a narrow yellow U-shaped band on sides and apex; tegula brown; mesopleuron brown; metapleuron dark brown. Fore wing rudiment infuscate, medially hyaline ( Fig. 22 ); hind wing hyaline, lightly infuscate basally and apically ( Fig. 23 ). Legs, including coxae, white, except as follows: fore and mid tarsal segments 1–4 yellow to pale brownish yellow, fifth segment dark brown; hind coxa in basal half brown, apical half white; hind femur whitish with base and apex slightly infuscate brown; hind tibia basally pale yellowish brown, becoming whitish apically; tarsal segments 1 and 2 yellow, 3 brownish yellow, 4 brown and 5 dark brown. Metasoma with petiole brownish yellow; gaster dark brown. Head, subprognathous, higher than broad; head, in dorsal view, with frontovertex 0.43× head width; ocelli small; ocellar triangle with apical angle a right angle; POL:OOL:OCL:AOL, 5:1:2.5:4; head, in frontal view ( Fig. 19 ), 1.34× as high as broad; eye height 3× malar space; head with silvery white setae. Antenna ( Fig. 21 ) flattened; scape slightly longer than head width, 0.83× head height, and 2.46× as long as broad; pedicel triangular, short; F1 as long as broad, 2.72× as long as pedicel, and 1.36× as long as F2; F1–F5 subequal in width; F2–F5 gradually, but slightly decreasing in length; F6 distinctly shorter and narrower than F5; clava 1.52× as long as broad, and very slightly longer than F5 and F6 combined. Relative measurements ( holotype , on card)—head dorsal width, 23; frontovertex width, 10; head frontal height, 31; eye height (head in profile), 24; malar space, 8; antennal scape length, 26. Mesosoma ( Fig. 20 ) slightly longer than metasoma (41:39); pronotum slightly longer than mesoscutum and 1.3× as broad as long; mesoscutum 1.58× as broad as long; scutellum 1.47× as long as broad; propodeum median length 0.24× scutellum length; setae on thorax short, pale brown; apical pair of scutellar setae detached. Fore wing ( Fig. 22 ) 4.14× as long as broad; hind wing ( Fig. 23 ) 5.14× as long as broad. Relative measurements ( holotype )— pronotum length (width), 13 (17); mesoscutum length (width), 12 (19); scutellum length (width), 12.5 (8.5); propodeum median length, 3. Metasoma ( Fig. 18 ). Hypopygium extending to apex of gaster. Male. Unknown. Material examined. Holotype , ♀ (on card, with right antenna and right wings on slide, No. EH.1780), labelled “ INDIA : KARNATAKA: Hessaraghatta, Fisheries Div[ision]., 26.iii.2014 (YPT), Coll. K. Veenakumari” ( NBAIR , registration No. ICAR / NBAIR /EN.42). Distribution. India : Karnataka. Etymology. Greek, brachys = short, pteron = wing; refers to the short wings in this species. FIGURES 17, 18. (17) Monstranusia antennata (Narayanan) . Female, Odisha specimen: body, dorsal. (18) Monstranusia brachyptera Hayat , sp. nov. Female: holotype: body, lateral view. Comments. This is the first record of brachyptery in Monstranusia Trjapitzin. This new species, excluding the short wings, is similar to the Indian species, M. antennata (Narayanan) , but differs mainly as follows: two longitudinal brown to dark brown bands on frontovertex and face connected by a transverse band at level of posterior ocelli ( Fig. 19 ); median longitudinal white band beginning at anterior end of pronotum and ending slightly anterior to apex of scutellum narrow throughout its length; scutellum with a narrow, U-shaped yellow band along margins ( Fig. 20 ); median length of pronotum slightly greater than median length of mesoscutum. In M. antennata : two longitudinal brown to dark brown bands on frontovertex and face connected at level of anterior ocellus by a transverse pale brown to dark brown band ( Fig. 17 ); median longitudinal white band beginning at anterior end of pronotum and ending at apex of scutellum gradually becoming wider towards apex; scutellum without a U-shaped yellow band along margins ( Fig. 17 ); median length of pronotum distinctly less than that of mesoscutum (median length of pronotum 0.76× mesoscutum length, in a slide-mounted mesosoma, and 0.86× mesoscutum length in a card-mounted specimen from Aligarh, Uttar Pradesh, not illustrated). See Noyes & Hayat (1994) for diagnosis and figures of this species.
