However, it differs from P. bicolor in the following characters: mesoscutum punctations are prominent all along the mesoscutum surface (punctations becoming indistinct posteriorly near scutellum in P. bicolor ); tegulae blackish brown (tegulae yellowish to pale yellowish in P. bicolor ) pterostigma about 3.0× as wide as long (pterostigma about 2.5× as wide as long in P. bicolor ); hind coxae black (hind coxae often yellowish in P. bicolor ); ovipositor sheaths 0.9 × as long as hind basitarsi, small and thick (ovipositor sheaths 1.1–1.2× as long as hind basitarsi, comparatively large with blunt apex in P. bicolor ); F2 2.3× as long as wide (F2 3.5× as long as wide in P. bicolor ); F5–F11 with double rank of placodes (F5–F6 with double rank of placodes in P. bicolor ). The new species is also very similar to P. circumscriptus . However, it differs from P. circumscriptus in the following characters: vein 1-R1 (metacarp) as long as or shorter than pterostigma (vein 1-R1 (metacarp) clearly longer than pterostigma in P. circumscriptus ); T2 subtriangular, 2.0× as wide as long posteriorly, hence more transverse (T2 strongly triangular, 3 × as wide as long posteriorly in P. circumscriptus ); forewing vein r and 2-SR meeting angularly (forewing vein r and 2-SR meeting each other less angularly in P. circumscriptus ). Fig. 3. Pholetesor indicus sp. nov. , paratype, ♀ (ZDAMU). A . Mesosoma, dorsal view. B . Propodeum, dorsal view. C . Metasoma, dorsal view. Scale bars: 0.25 mm. Apart from the similarities with P. bicolor , the new species also runs close to P. teresitergum Liu & Chen, 2016 in the key to the Chinese species of the genus Pholetesor ( Liu et al. 2016 ) . However, it differs from P. teresitergum in the following characters: eyes 2.2× as long as temple in dorsal view (eyes 1.6× as long as temple in dorsal view in P. teresitergum ); ocelli large (ocelli relatively small in P. teresitergum ); scutellum highly polished (scutellum punctate with hairs in P. teresitergum ); ovipositor sheaths small and thick, slender with a bluntly rounded tips, (ovipositor sheaths small and subfusiform in P. teresitergum ); tegulae blackish brown (tegulae yellowish in P. teresitergum ).
