( Figs 1–10 )

Description. Female. Length, 0.30 (paratype, 0.33) mm. Head with frontovertex, face, gena and occiput dark brown; eyes and ocelli deep red. Mandible brown. Antenna pale brown except scape dorsally, and posterodorsal one-third of pedicel brown. Mesosoma uniformly dark brown. Fore wing hyaline, with slight infuscation basally from below venation and with two brown patches, one below premarginal vein and other along posterior wing margin opposite of marginal vein. Hind wing hyaline. Legs pale brown except coxae, basal half of fore femur, and hind femur dark brown. Metasomal terga dark brown except pale at posterior end of gaster.

Head, in frontal view, as broad as high; frontovertex with 12 short and strong setae and sculpture as given in Fig. 1 ; ocelli arranged in obtuse triangle; eye setose, setae hyaline, each seta shorter than a facet. Antenna ( Figs 5–8 ) with scape cylindrical, 2.7× as long as broad; pedicel 1.33× as long as broad, with three long and strong setae; second anellus (A2) appressed into base of F1 ( Fig. 7 ); funicle ( Figs 5, 7 ) 2-segmented with F1 short and scale-like, shorter than F2, and with 1 PLS, F2 broader than Fl, and with 3 PLS, both segments with basiconic peg sensilla, 0.81× as broad as long; clava 3- segmented (C1, C2 and C3), each segment provided with 2 PLS and few basiconic peg sensilla, 2.6× as long as broad. Relative measurements: length of malar space, 20; width of eye, 20; length (width) of scape, 27 (10); pedicel, 16 (12); funicle, 13 (16); clava, 43 (16).

Mesosoma ( Fig. 9 ). Mid lobe of mesoscutum 1.23× as broad as long and 1.54× as long as scutellum; scutellum 2.36× as broad as long, with anterior setae very short; propodeum distal to each spiracle with 1 long seta and with 2 setae proximally; other setae on mesothoracic tergites as given in generic description. Fore wing ( Fig. 4 ), 2.41× as long as broad; marginal fringe 3.39× wing width. Hind wing 12.8× as long as broad and with 3 rows of setae; marginal fringe 1.8× wing width. Relative measurements: length (width) of mid lobe of mesoscutum, 34 (42); scutellum, 22 (52); median length of metanotum, 4; propodeum median length, 6; fore wing length (width), 188 (78); fringe length of fore wing, 23; hind wing length (width), 128 (10), fringe length of hind wing, 18; lengths of fore, mid and hind tibiae, 47:60:63.

Metasoma ( Fig. 10 ).Gaster short, broad and rounded, about 1.6× as long as mesosoma; TI of gaster with sculpture anteriorly as in Fig. 9 ; TII with one pair of setae and TIII–TVI with two pairs of setae arranged laterally; ovipositor ( Fig. 10 ) 0.77× length of hind tibia. Relative measurements: length of gaster, 106; length of ovipositor, 49.

Male. Unknown.

Material examined. Holotype, f# (on slide, under 4 coverslips), labeled “ INDIA: UTTAR PRADESH: Aligarh, Jamalpur , 17.ix.2013, Coll. MT Khan. Paratype . 1 f# (on slide under 3 coverslips), labeled “ INDIA: UTTAR PRADESH: Mainpuri, Malau , 06.ix.2007, Coll. F.R. Khan.

Distribution. India: Uttar Pradesh.

Etymology. The species name is derived from the globular shape of the gaster. The first four letters globu taken from globular + gaster.
