Umairia laiba Hayat , sp. nov.

Female. Holotype. Length, 1.0 mm. Head largely yellow to brownish yellow, frons and malar space brown, face white. Antenna with scape yellow, basally pale brownish yellow; pedicel brown; F1–F3 pale brownish yellow; clava white. Pronotum pale yellow; mid lobe of mesoscutum brownish, side lobes yellowish white; axilla and scutellum brownish yellow; sides of propodeum dark brown; mesopleuron pale brown in upper half becoming dark brown in lower half. Fore wing ( Fig. 22 ) hyaline, with a light infuscation below parastigma, an infuscate streak from proximal end of parastigma to posterior margin, and with an infuscate patch in posterior half of disc below proximal half of marginal vein. Hind wing hyaline. Legs, including coxae, white; femora brownish on both margins, and tibiae brownish at base. Gaster dark brown, with TI white except for a dark brown band on each side; third valvula white.

Head ( Fig. 16 ), in frontal view, slightly higher than broad; minimum width of frontovertex 0.51× head width; frons with a fine longitudinal groove in front of anterior ocellus; scrobes shallow, with rounded margins [scrobes not discernible in slide-mounted head]; malar space 0.54× eye height; frontovertex and face smooth, without any sculpture, except for some fine longitudinal lines on malar space; head with very fine, short hyaline setae, except a pair of long, brown setae just behind posterior ocelli, and a long brown seta on vertex between each posterior ocellus and margin of eye; eye apparently bare, but very fine, short setae visible at higher magnification. Mandible as in Fig. 17 . Antenna ( Fig. 18 ) with scape 4.4× as long as broad; pedicel longer than F1 and F2 combined; funicle segments transverse; clava 2.38× as long as broad, and as long as pedicel and funicle combined; longitudinal sensilla absent on F1, sensilla present on F2, F3 and clava. Relative measurements (holotype, slide) at 100×—head frontal width, 31; head frontal height, 33; frontovertex width at narrowest, 16; eye height, 17.5; malar space, 9.5; antennal scape length, 18.75. Antennal segments length (width) at 400×—scape, 75 (17); pedicel, 21 (13); F1, ventral, 8 (13.5); F2, dorsal, 10 (14); F3, dorsal, 11 (18); clava, 50 (21).

Mesosoma ( Fig. 19 ). Pronotum with very fine, polygonal, transversely elongate reticulate sculpture; mid lobe of mesoscutum in anterior fourth or so with slightly raised, transversely elongate reticulate sculpture, rest of mid lobe smooth, but with about three lines of very fine, longitudinally elongate reticulate cells medially; side lobe of mesoscutum smooth; axilla with very fine, polygonal reticulate sculpture; scutellum with raised polygonal reticulate sculpture, cells slightly elongate ( Fig. 20 ); metanotum medially and propodeum medially in a triangular area with fine polygonal reticulations; propodeum on each side proximal to spiracles with a curved ridge; setae on mesosomal tergites as follows: each half of pronotal collar with a line of short setae, and a long seta at posterolateral corner; mid lobe of mesoscutum with a pair of long, dark setae in about anterior third, and a curved line of 6 small setae anterior to submedian pair, otherwise disc bare; each side lobe of mesoscutum with 3 small and 1 long seta; distance between posterior pair of scutellar setae 2× the distance between anterior pair; propodeum distal to spiracle with 5 setae. Fore wing ( Fig. 22 ) 2.5× as long as broad; costal cell 1.66× as long as marginal vein; stigmal vein as in Fig. 23 ; other details as given in generic description. Hind wing 5.75× as long as broad; marginal fringe 0.54× wing width. Relative measurements (holotype, slide)—mesosoma length, 38; mesoscutum length (width); 16 (26); scutellum length (width), 12 (17.5); width of axilla, 5; width of anterior margin of scutellum, 10; mid tibia length, 32.5; mid basitarsus length, 7; mid tibial spur length, 6.

Metasoma, on slide, slightly longer than mesosoma (44:38); ovipositor extends from about posterior end of TII of gaster, and exserted to 0.17× gaster length ( Fig. 21 ); setae on TI–TVII as follows: TI, 0 + 0; TII, 3 + 3; TIII, 4 + 3; TIV, 4 + 3; TV, 2 + 2; TVI, 2; TVII, 6. Relative measurements (holotype, slide)—ovipositor length, 33; third valvula length, 10.

Male. Length, 0.65 mm. (gastral tergites retracted). Similar to female in colour, sculpture, setation of head and mesosoma, but differs as follows.

Head, in frontal view, as broad as high; malar space slightly convergent, and 0.67× eye height ( Fig. 24 ). Antenna ( Fig. 25 ) with scape 4.57× as long as broad; pedicel 1.14× as long as broad, and subequal in length to F1; F1 quadrate; F2 slightly longer than broad and slightly longer than F1 (17:15:15); F3 1.35× as long as broad; clava about as long as funicle; funicle segments all with longitudinal sensilla. Genitalia ( Fig. 26 ) with phallobase short, anteriorly rounded; parameres short; digiti long, 0.36× phallobase length, and each digitus with two short denticles; aedeagus 1.47× as long as phallobase. Relative measurements (slide) at 400×—mid basitarsus length, 24; mid tibial spur length, 22; phallobase length, 36; digitus length, 13; aedeagus length, 53.
