Diagnosis. Even though P. flava exhibits morphological characters of Exoryza Mason, 1981 , we maintain this species under Promicrogaster based on the following character similarities with other species of the genus; long ovipositor sheaths (2.4 × as long as metatibia), propodeum carination, and enlarged lunules on lateral face of scutellum. This new species is readily distinguished from the Oriental species by its propodeum with complete areola ( Fig. 5F View FIGURE 5 ), metasoma completely yellow ( Figs 5A View FIGURE 5 , 6A, B View FIGURE 6 ), and second metasomal suture distinctly impressed and crenulated ( Fig. 6B View FIGURE 6 ). Promicrogaster flava sp. nov. is similar to P. incompleta sp. nov. based on its parallel-sided mediotergite 1. Apart from the differences listed under the diagnosis section of P. incompleta , it differs based on the following characters; dorsal length of eye 1.8 × as long as gena (1.4 × in P. incompleta sp. nov.), middle lobe of mesoscutum not convex or elevated (distinctly elevated in P. incompleta sp. nov.), fore wing vein 1CUa 0.6 × as long as 1Cub (as long as 1CUb in P. incompleta sp. nov.), and metafemur 4.5 × as long as its maximum width (2.8 × in P. incompleta sp. nov.).
