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 View FIGURES 36–48 ) [vs 0.8 × in N. pinguis , cf. Fig. 4C View FIGURES 2–11 in Ranjith & Priyadarsanan (2021)]; 2) Midbasal area of second metasomal tergite 0.4 × second tergite length ( Fig. 47 View FIGURES 36–48 ) [vs 0.75 × in N. pinguis , cf. Fig. 5A View FIGURES 2–11 in Ranjith & Priyadarsanan (2021)]; and 3) Pronotum and mesoscutum black ( Fig. 39 View FIGURES 36–48 ) [vs yellow in N. pinguis , cf. Figs 4D, E View FIGURES 2–11 in Ranjith & Priyadarsanan (2021)].
