Wings. Fore wing (Fig. 44): length of pterostigma 4.0 × its width; angle between vein C+SC+R and 1-RS about 70°; vein 1-RS+M curved basally; ratio of length of veins r: 2-RS: 3-RS: SR1 = 9: 18: 37: 61 and 2-RS: 3-RS: r-m = 19: 37: 11; vein 1cu-a slightly postfurcal; second submarginal cell parallel sided, basal length 5.0 × its apical width (Fig. 44).

Biology. Unknown.
Etymology. The new species is named after the granddaughter of the second author, Khuat Ha Linh.
Notes. Nedinoschiza khuathalinhae sp. nov. is similar to Nedinoschiza pinguis Papp, from China in having the longitudinally striated midbasal area of second metasomal tergite and sculptured third metasomal tergite, but differs from N. pinguis by the following characters: 1) Length of eye 1.3 × as long as temple in dorsal view (Fig. 36) [vs 0.8 × in N. pinguis, cf. Fig. 4C in Ranjith & Priyadarsanan (2021)]; 2) Midbasal area of second metasomal tergite 0.4 × second tergite length (Fig. 47) [vs 0.75 × in N. pinguis, cf. Fig. 5A in Ranjith & Priyadarsanan (2021)]; and 3) Pronotum and mesoscutum black (Fig. 39) [vs yellow in N. pinguis, cf. Figs 4D, E in Ranjith & Priyadarsanan (2021)].
