( Figs 116–125 )

Ooctonus himalayus Subba Rao 1989: 140 (key), 142, 171 (illustrations), 173 (illustration); holotype female [BMNH], not examined; type locality: Manali , Himachal Pradesh, India.

Type material examined. Paratypes: 1 female [ BMNH] on slide labeled: 1. “1988 Para-type [inside yellowbordered circle glued onto the label] ♀ Ooctonus himalayus sp. nov. B.R. Subba Rao det”, 2. “ INDIA: Him. Pr. Manali 12.X.1979 Z. Boucek 18 Mar 87” ; 3 females [ BMNH] on individual cards/pins labeled: 1. “ INDIA, Him. Pr. Manali 9.X.79 [except 1 female 10.X.79] Bouček”; 2. “ Ooctonus himalayus sp. nov. ♀ det. B.R. Subba Rao, 1988”; 3. [inside yellow-bordered circle] “Para-type” .

Material examined. NEPAL. BAGMATI, Lalitpur District, Phulcoki , 2600 m: 14.x.1983, A. Smetana [2 ♀, CNCI, UCRC]; 14.x.1983, A. Smetana, I. Löbl [1 ♂, CNCI] . DHAWALAGIRI (DHAULAGIRI), Goropani Pass (also spelled as Ghoropani, Gorepani , or Ghorepani ), 2850 m, 5.x.1983, A. Smetana [1 ♀, CNCI] .

Redescription. FEMALE. Body length (one card-mounted specimen from Nepal measured) about 1300 µm. Body almost entirely dark brown to almost black except eyes and ocelli dirty pink, petiole pale to yellowish brown, and apical gastral terga brown; scape and pedicel mostly light brown, funicle brown to dark brown, clava dark brown; legs mostly light brown except coxae dark brown, femora and metatibia partially brown, and apical tarsomeres brown.

Head as in Fig. 117 . Antenna ( Fig. 116 ) with scape a little longer than clava, radicle about 0.2x length of scape, remainder of scape 5.0–5.2x as long as wide, a little wider medially than basally or apically; pedicel shorter than F1; all funicle segments much longer than wide and more or less subequal in length (F2 and F5 slightly longer, F7 and particularly F8 slightly shorter), F5–F8 each with 2 mps; clava 3.4–3.5x as long as wide, almost as long as combined length of F6–F8, with 7 mps.

Mesosoma ( Fig. 118 ) with pronotum weakly sculptured; mesoscutum and anterior scutellum with reticulate sculpture (sometimes notably less pronounced on the posterior half or so of midlobe of mesoscutum), posterior scutellum with weak sculpture only at anterior and lateral margins, otherwise mostly almost smooth (or with very inconspicuous sculpture), midlobe of mesoscutum without a median groove or at most with a very short median groove just at posterior margin of mesoscutum (less than 0.1x its length); metanotum smooth, shining, with posterior margin broadly rounded; propodeum ( Fig. 119 ) mostly smooth, with median carina short, subparallel to long lateral carinae that extend to anterior margin of propodeum.

Forewing ( Fig. 120 ) 2.7–2.8x as long as wide; disc with a slight brownish tinge throughout (more pronounced behind apex of submarginal vein and the very base of marginal vein), densely setose but bare behind base of submarginal vein, slightly truncate apically; longest marginal seta about 0.2x greatest width of wing. Hind wing ( Fig. 120 ) 15–16x as long as wide; disc with a slight brownish tinge and densely setose throughout; longest marginal seta 1.8–2.0x greatest width of wing.

Pro- and mesocoxae smooth, metacoxa with strong reticulate sculpture.

Petiole 3.8–4.0x as long as wide, a little wider apically than basally, smooth, about 1.3x as long as metacoxa; ovipositor occupying 0.6–0.8x length of gaster, slightly exserted beyond apex of gaster (by 0.1–0.14x own length), 0.9–1.0x length of metatibia.

Description. MALE (previously undescribed, specimen from Nepal). Similar to female except for the normal sexually dimorphic features and the following [body length is impossible to measure because of the way the detached head is slide-mounted]. Antenna ( Fig. 121 ) with scape plus radicle light brown to brown, about 4.4x as long as wide, pedicel brown, flagellum dark brown; posterior third or so of midlobe of mesoscutum almost smooth, propodeum ( Fig. 122 ) without median carina; forewing ( Fig. 123 ) about 2.9x as long as wide; hind wing as in Fig. 124 ; genitalia as in Fig. 125 .

Diagnosis. Ooctonus himalayus is the only described Oriental species of Ooctonus that either lacks a median groove on the midlobe of the mesoscutum or at most has a very short median groove just at its posterior margin (less than 0.1x length of mesoscutum).

Distribution. ORIENTAL: India (Himachal Pradesh), and Nepal *.

Hosts. Unknown.
