(Figs 16–22)
Description. FEMALE (holotype, Fig. 16). Entire body and antenna brown except scape, pedicel, T1 and T2 paler; eye reddish; legs pale.
Eye normal; ocelli present (Fig. 17). Antenna with scape in lateral view straight (Fig. 18a), scape minus radicle 4.1× as long as wide; pedicel 1.5× as long as wide, 2.6× as long as fl1; all funicle segments without mps, fl1–fl6 each wider than long; clava (Fig. 18b) 3.0× as long as wide, with 6 mps and 2.7× as long as combined length of fl3–fl6.
Mesosoma 0.7× as long as gaster (Fig. 21), with frenum laterally strongly and medially weakly longitudinally striate. Propodeum about 1.6× as long as mesoscutum.
Brachypterous. Fore wing (Fig. 19) 16.0× as long as wide, venation 0.51× as long as wing length; parastigma with both macrochaetae moderately long (18–43 µm); disc slightly infuscate, with one complete median row of irregular setae and one complete admarginal row of setae along anterior and posterior margins, the former less prominent, densely setose behind marginal and stigmal veins; longest marginal seta 7.1× wing width. Hind wing (Fig. 20) 21.6× as long as wide; disc with an irregular, incomplete median row of setae in addition to one complete admarginal row of setae along anterior margin and an incomplete row of setae along posterior margin; longest marginal seta 7.5× wing width.
Gaster 1.3× as long as mesosoma (Fig. 22); ovipositor about 1.0× length of metatibia.
Measurements in µm (holotype, as length or length/width): Body, 500. Head, 133/110. Antenna: radicle, 18/13; rest of scape, 103/25; pedicel, 35/23; fl1, 13/18; fl2, 15/18; fl3, 13/18; fl4, 15/20; fl5, 13/23; fl6, 15/25; clava, 150/50. Fore wing, 370/23; longest marginal seta, 165. Hind wing, 325/15; longest marginal seta, 113. Mesosoma, 183/135; mesoscutum, 55/115; anterior scutellum, 23/53; frenum, 48/80; propodeum, 88/120. Gaster, 238/130; ovipositor, 153. Metatibia, 155.
Variation (paratypes): no variation was observed in body length or color.
MALE. Unknown.
Diagnosis. Among the Oriental species of Cleruchus, C. indicus is somewhat similar to C. blimp in having transverse funicular segments and ovipositor at least 0.8× of metatibia length. However, it can be differentiated from the latter taxon based on fl5 being the shortest, the clava being 2.7× as long as combined length of fl3–fl6, and the fore wing having a complete admarginal row of setae along its posterior margin and being prominently setose behind the marginal and stigmal veins (in C. blimp fl5 longest, clava 1.7× as long as combined length of fl3– l6, and fore wing without admarginal row of setae along posterior margin except for an incomplete row of very few short, inconspicuous setae behind marginal and stigmal veins).
Type material. Holotype female on slide, dissected under 4 coverslips (EDAU, registration No. Mym /26/ 2017): INDIA, Tamil Nadu, Thiruvannamalai, Keelpalur, 12°23’20.51’’N 78°56’51.20’’E, 5.x.2014, N. Gowthaman & M. Ayyamperumal, YPT, forest ecosystem. Paratypes: 2 females on cards in EDAU, same data as holotype.
Distribution. India: Tamil Nadu.
Etymology. The new species name is derived from the name of the country in which the specimens were collected.
