Ooctonus flavipodus Subba Rao, 1989

( Fig. 115 )

Ooctonus flavipodus Subba Rao 1989: 140 (key), 143, 172 (illustration); holotype female [BMNH], not examined; type locality: Sangu, Taplejung District, Mechi Zone, Nepal [erroneously indicated as “ Burma ” ( Myanmar) by Subba Rao (1989: 143)].

Type material examined. Paratypes: 1 female [ BMNH] on point labeled: 1. “TAPLEJUNG DISTR., Sangu, c 6200'”, 2. “Mixed vegetation by stream in gully. xi.1961 – i.1962.”, 3. “BRIT. MUS. East Nepal Exp. 1961– 62.”, 4. “ R.L. Coe Coll. B.M.1962–177”, 5. “ Ooctonus flavipodus sp. nov. ♀ det. B.R. Subba Rao, 1988”, 6. [inside yellow-bordered circle] “Para-type” ; 1 male [ BMNH] on point labeled: 1. “TAPLEJUNG DISTR., below Sangu”, 2. “By stream in shady ravine. c. 6000' 30.x.1961.”, 3. “BRIT. MUS. East Nepal Exp. 1961– 62.”; 4. “ Ooctonus flavipodus sp. nov. ♂ det. B.R. Subba Rao, 1988”, 5. [inside yellow-bordered circle] “ Paratype ”. The female paratype specimen lacks one fore leg, one middle leg (except for a coxa), and both hind legs, and the metasoma is detached from the rest of the body and glued on the point separately ( Fig. 119 ); the male paratype specimen lacks a part of one of the antennae .

Redescription. FEMALE (paratype). Length approximately 1350 µm. Body ( Fig. 115 ) almost entirely dark brown except eyes and ocelli dirty pink and petiole light brown; scape, pedicel, and F1–F3 light brown, F4–F8 and clava dark brown; legs light brown except distal tarsomeres a little darker (brown).

Scape a little shorter than clava; all funicle segments much longer than wide and more or less subequal in length (F2 and F3 a little longer and F8 a little shorter), F1 longer than pedicel; mps apparently present at most on F4–F8 (but that is impossible to verify without slide-mounting of an antenna from the holotype or the paratype).

Mesosoma with pronotum smooth; mesoscutum and anterior scutellum with reticulate sculpture (the cells larger on mesoscutum than on anterior scutellum), midlobe of mesoscutum with a median groove about as wide posteriorly as width of a notaulus, anteriorly narrowing and extending to about half length of mesoscutum; posterior scutellum with weak sculpture only at anterior and lateral margins, otherwise smooth and shining, metanotum strap-like, smooth, shining; propodeum mostly smooth, with median carina about as long as median areole, lateral carinae not parallel to median carina, each split anteriorly as a short, broadly Y-shaped carina.

Forewing approximately 3.0x as long as wide; disc with a slight brownish tinge throughout, densely setose but bare behind most of submarginal vein, with discal setae only just behind its apex along posterior margin of the wing, slightly truncate apically.

Petiole mostly smooth except for a few longitudinal striations; gaster shorter than mesosoma; ovipositor not exserted beyond apex of gaster.

MALE (paratype). Similar to female except for the normal sexually dimorphic features.

Diagnosis. Ooctonus flavipodus differs from O. lapen sp. n., the only other known Oriental species of the genus that has all the coxae lightly colored, by the contrastingly lighter color of F1–F3 of the female antenna relative to much darker color of other funicle segments, whereas in O. lapen all funicle segments are dark brown.

Distribution. ORIENTAL: Nepal.

Hosts. Unknown.

Comments. One female Ooctonus sp. in UCRC ( THAILAND. PHETCHABURI, Kaeng Krachan National Park, 12°49.243’N 99°22.256’ E, 890 m, 24–26.vi.2008, B.V. Brown) is very similar to O. flavipodus except for having only F1 of the antennal funicle yellowish while F2–F8 are contrastingly dark brown. It is possible that this specimen may be just a mere color variation of O. flavipodus .
