Forewing ( Fig. 1 d ) characteristic with apical margin, between PM and apical apex of wing, bare; basal vein bare, speculum open below and continued as a broad bare stripe below M to somewhat beyond ST, except with a few setae near base of ST; distal part of wing rather sparsely clothed with short setae; costal cell about 1.33 times as long as M and about 8 times as long as broad; SM with 4 dorsal setae; M 3.75 times length of ST, its front edge with 8-9 setae; ST bare except for 2 setae in the middle of the stigma; PM nearly half as long as ST.

Hypopygium as in fig. 3 b.

Color yellow, head with eyes red; having fuscous spot on both sides of clypeus occipital surface just above foramen magnum, scape and pedicellus dorsally black, funicular segments apically fuscous; a fuscous dot above each prothoracic spiracle, scuto-axillar sutures and a transverse fuscous band on the hind edge of each gastral tergite; tips of ovipositor sheaths fuscous. Pronotum almost white. A pair of large spots on the front part of mid lobe of mesoscutum, and a small spot on the front of each scapula and axilla are tan-coloured. Forewing hyaline. Length 1.8-2.7 mm.

Forewing as in female, PM ST bare except for 1 seta in the middle of the stigma. Gaster oblong-elliptic, about 1.33 times as long as thorax, about as broad as thorax, with ventral plica. Genitalia ( Fig. 3 d ) distinctly exerted from tip of gaster, about 0.73 as long as gaster, 10.4 times as long as broad, digitus about 1.5 times as long as broad. Length 1.3- 2.0 mm.

Color as in female but antenna black, except ventral surface of scape yellow, a fuscous spot on occipital surface just above foramen magnum, another in middle of front margin of mesonotum; notauli, suture on mesonotum, sublateral lines of scutellum, front and hind margin of propodeum, last tergum of gaster black, genitalia pale brown.

C o m m e n t s Kolopterna nov.sp. is similar to Kolopterna kohatensis GRAHAM in having forewing with apical margin, between PM and apical apex of wing, bare; basal vein bare, speculum open below and continued as a broad bare stripe below M to somewhat beyond ST, except with a few setae near base of ST; distal part of wing rather sparsely clothed with short setae. In other species of Kolopterna forewing with apical margin having distinct ciliae.

Kolopterna aymani differs from K. kohatensis in female with POL 2.33 times OD; antenna with scape reaching slightly above level of vertex; pedicellus plus flagellum about 1.3 times breadth of mesoscutum; costal cell about 1.33 times as long as M and about 8 times as long as broad; ST bare except for 2 setae in the middle of the stigma (in K. kohatensis POL twice OD; antenna with scape not reaching level of vertex; pedicellus plus flagellum about equal to breadth of mesoscutum; costal cell 1.7 times as long as M and about 10 times as long as broad; ST bare except for 1 seta in the middle of the stigma); in male antenna with scape 1.3 times as long as eye; with ventral plaque 0.23 length of scape; pedicellus plus flagellum about 2.2 times breadth of mesoscutum; clava slightly narrower than F4, 7 times as long as broad, C3, including spicula, 3 times as long as broad; whorled setae long, those of F1 reaching about level with about basal 1/3 of F3; forewing with PM half as long as ST; genitalia 10.4 times as long as broad, digitus about 1.5 times as long as broad (in K. kohatensis antenna with scape 1.05 times as long as eye; with ventral plaque 0.27 length of scape; pedicellus plus flagellum about 1.7 times breadth of mesoscutum; clava hardly broader than F4, 5 times as long as broad, C3, including spicula, about twice as long as broad; whorled setae long, those of F1 reaching about level with tip of F3; forewing with PM rudimentary; genitalia 5.7 times as long as broad, digitus twice as long as broad
