Head ( Fig. 18 ): vertex, frons and postclypeus pale brown yellowish, an irregular line of brown spots from upper angle of each compound eye to ocellar group; another similar line from lower angle of each compound eye to epistomal sulcus, next to antennal fossae; a dark brown area between ocellar group and epistomal sulcus; genae pale yellowish. Postclypeus with thick, brown diagonal striae. Antennae: Scape, pedicel and flagellum creamy, with distal flagellomeres pale brown, maxillary palpomeres creamy white. Legs creamy white, tarsi pale brown, pretarsus brown. Tergal lobes of meso- and metathorax brown, pleura creamy, with pale brown longitudinal line. Fore wings with brown spots as illustrated ( Fig. 17 ); pterostigma with a distal brown spot, cell M almost hyaline, areola postica with pale brown spot at apex, distal half of wing with a series of radial spots on cells R 2+3, R 4+5 and M1-M3. Hind wings hyaline, veins creamy white. Abdomen creamy. Epiproct, paraprocts and subgenital plate creamy, V1 with a brown band along outer border, V2 proximally brown, V3 creamy white.

Morphology. Head almost straight at vertex, compound eyes little pedunculate, H/MxW: 0.96, MxW/MnW: 1.52; C: 160 microns. Antennae with short setae. Fore wing ( Fig. 17 ): L/W: 2.54, pterostigma much wider posteriorly, lp/wp: 3.21; Rs slightly curved and shorter than R 2+3; cell M almost rectangular; areola postica trapeziform. Hind wing Rs-M fused, Rs about four times as long as the fused length; vein R 4+5 1.1 times as long as Rs. Ovipositor valvulae ( Fig. 21 ): V1 slender, elongate, pointed, inner border with a field of microspines; V2 long, broad, stout, more sclerotized anteriorly, posteriorly with a small, pointed projection, V3 about half as long as V2, almost ovoid, posterior border with a row of macrosetae, other setae on surface as illustrated; a small triangular projection near the middle. Ninth sternum membranous ( Fig. 21 ), spermapore sclerite rhomboid, with small, circular spermapore in the middle. Subgenital plate broad ( Fig. 19 ) with setal field in the middle, posterior projection short, apically rounded, with a field of setae. Paraprocts ( Fig. 20 ) broadly triangular, apex rounded, with a row of macrosetae on outer border, sensory fields with 28−30 trichobothria in basal rosettes. Epiproct ( Fig. 19 ) trapeziform, posteriorly rounded, with setae as illustrated.
