Cleruchus orientalis Manickavasagam & Palanivel , sp. n.

( Figs 23–32)

Description. FEMALE (holotype, Fig. 23). Body brown except intersegmental areas of metasoma and legs paler; eye pink.

Eye normal; ocelli present ( Fig. 25 ). Antenna ( Fig. 26a ) with scape minus radicle 4.0× as long as wide; pedicel 1.7× as long as wide, much longer than fl1; funicle segments without mps, fl1 1.15× as long as fl2, fl2–fl3 equal, fl4– fl5 equal, fl6 quadrate; clava ( Fig. 26b ) 3.0× as long as wide, with 5 mps and 1.5× as long as combined length of fl3– fl6.

Mesosoma 0.8× as long as metasoma ( Fig. 29 ), with anterior scutellum and frenum medially faintly reticulate, and lateral lobe of mesoscutum, axilla and frenum laterally longitudinally striate. Propodeum 1.3× as long as mesoscutum.

Macropterous. Fore wing ( Fig. 27 ) 13.1× as long as wide, venation 0.36× as long as wing length; parastigma with both macrochaetae equal in length (38 µm) and shorter than stigmal seta; disc slightly infuscate, with a complete median row of setae, in addition to one complete admarginal row of setae along anterior margin except for a few less prominent setae along the posterior margin beyond venation; longest marginal seta 4.0× wing width. Hind wing ( Fig. 28 ) 22.8× as long as wide; disc infuscate, with an incomplete median row of setae in addition to a complete admarginal row of setae along anterior margin again except for a few less prominent setae beyond venation; longest marginal seta 6.1× wing width.

Petiole 4.0× as wide as long; ovipositor 0.5× length of metatibia ( Fig. 30).

Measurements in µm (holotype, as length or length/width): Body, 600. Head, 115/158. Antenna: radicle, 15/13; rest of scape, 120/30; pedicel, 40/23; fl1, 23/18; fl2, 20/20; fl3, 20/20; fl4, 23/20; fl5, 23/20; fl6, 23/23; clava, 138/45. Fore wing, 590/45; longest marginal seta, 180. Hind wing, 570/25; longest marginal seta, 153. Mesosoma, 255/ 155; mesoscutum, 85/150; anterior scutellum, 43/63; frenum, 30/95; propodeum, 118/130. Metasoma, 300/150; ovipositor, 113. Metatibia, 203.

Variation (paratypes): body length 585–750 µm.

MALE (paratype, Fig. 24). Similar to female except for antenna (flagellum 9-segmented, scape much shorter than in female, Fig. 31 ) and genitalia (about 0.6× as long as metatibia, Fig. 32 ).

Measurements in µm (paratype, as length or length/width): Body, 575. Antenna: scape minus radicle, 70/28; pedicel, 28/30; fl1, 15/15; fl2, 15/18; fl3, 18/23; fl4, 18/20; fl5, 20/23; fl6, 25/20; fl7, 25/25; fl8, 28/25; fl9, 35/20. Genitalia, 95. Metatibia, 150.

Diagnosis. Females of this new species are similar to those of the European species C. leptosoma Debauche , in having the fore wing with 2 complete rows of setae (one median row and the other along anterior margin) and another short, incomplete row. They differ from C. leptosoma females by the following: pedicel 1.7× as long as wide, pronotum short ( Fig. 29 ), mesosoma sculptured, ovipositor 0.5× length of metatibia (in C. leptosoma pedicel 2.1× as long as wide, pronotum long (fig. 14 of Triapitsyn 2014a, p. 18); mesosoma smooth; ovipositor 0.8–0.9× length of metatibia).

Type material. Holotype female, dissected on slide under 4 coverslips ( EDAU; registration No. Mym /27/ 2017): INDIA, Manipur, Kakching Khounou Lamkhai, (760 m 24.24° N 93.54°E), 21.i.2013, Sophis Singh, YPT, on pineapple . Paratypes (47 ♀, 6 ♂): (1 ♀, 2 ♂ on slides and 25 ♀ on cards ( EDAU), same data as in holotype) ; (21 ♀, 4 ♂ on cards, 7.i.2014, same data as in holotype except for the date). Two female and two male paratypes in NBAIR and another two female and two male paratypes in ZDAMU, and remaining paratypes in EDAU .

Distribution. India: Manipur.

Etymology. The species is named after the zoogeographical region of the type locality.
