Ooctonus clebschi Huber , sp. n.

( Figs 1, 2 , 7, 15, 18, 22)

Type material. Holotype ♀ in CNC, on slide ( Fig. 22 ) with two labels: 1. “ Mexico: Oaxaca Llano de las Flores, 15 mi NE. Ixtlan de Juarez 21.vii.1985, J. Woolley & G. Zolnerowich”. 2. “ Ooctonus clebschi Huber Holotype ♀ dorsal”.

Paratypes (5 ♀). MEXICO. Michoacán. 6 mi. N. Cheran, 8.vii.1985, J. Woolley, G. Zolnerowich (1♀, CNC). Oaxaca. Same data as holotype (2♀, CNC, UCRC); 1.4 mi NE La Cumbre, 18.vii.1985, J. Woolley, G. Zolnerowich (1♀, CNC); Santiago Comaltepec, hwy 17 km 108, Cerro Humochico, 2948m, 17.58º N 96.51º W, H. Clebsch, dense oak/pine forest, YPT (1♀, CNC).

Diagnosis. Clava with a cluster of 4–6 (rarely as few as 3) bullae just beyond middle and another near apex (Fig. 7); clava at most 230 Μm long.

Females of O. clebschi are very similar to those of O. zolnerowichi except the clava is shorter and has far more bullae. Because females of the two species cannot be distinguished unless the bullae on the clava can be examined their correct identification requires cleared, slide mounted specimens. As a consequence, body length and colour cannot be described from critical point dried specimens because their identity is uncertain.

Description. Female. Body length and colour probably as for O. woolleyi (see below). Head. Width 306–393 (n=5). Vertex without stemmaticum ( Fig. 1 ). Mid ocellus diameter 23–27. Antenna. Length/width measurements (n=6): scape 226–283, pedicel 67–82, fl1 72–107, fl2 78–115, fl3 70–96, fl4 54–70, fl5 56–76, fl6 41–66, fl7 61–75, fl8 57–71, clava 177–230. Flagellum (Fig. 7) total length 496–635; with 2 or, less often, 1 or rarely 0 mps on fl5, 0 or 1 or rarely 2 mps on fl6, and 2 mps on fl7 and fl8; fl2 the longest funicle segment; fl1–fl6 length/width ratios (n=6): fl1 4.26–4.90, fl2 4.06–4.95, fl3 3.09–3.93, fl4 2.20–2.59, fl5 1.99–2.42, fl6 1.55–1.99; clava 3.04–3.83× as long as wide, slightly longer than fl6– fl8 together, with 7 mps and (internally) with two clusters of bullae. Mesosoma. Pronotum with collar moderately short ( Fig. 15 ) but visible in dorsal view, with well defined transverse carina. Mesoscutal midlobe with engraved meshes; scutellar seta long, extending posteriorly to medially slightly concave frenal line; axilla reticulate, lateral panel of axilla and axillula smooth; frenum entirely reticulate. Metanotum with dorsellum smooth and lateral lobes with 2 longitudinal carinae ( Fig. 15 ). Propodeum ( Fig. 15 ) smooth between carinae; anterior margin with propodeal stub slightly lateral to lateral margin of dorsellum; median areole separated from dorsellum by a short carina; plica straight, its anterior limit in line with apex of stub. Wings. Fore wing ( Fig. 18 ) length 1321–1642, width 453–632, length/width 2.55–2.92, and longest marginal setae 100–114, at most about 0.2× as long as greatest wing width (n=6). Hind wing ( Fig. 18 ) length (n=6) 969–1253, width 54–82, and longest marginal setae 113–154. Metasoma. Petiole shorter than metacoxa + metatrochantellus. Gaster with ovipositor length 435–549 (n= 6), 0.92–1.06× as long as metatibia length (404–574), and projecting slightly beyond gastral apex.

Male. Unidentifiable to species, but probably present in material examined.

Etymology. The species is described in honour of Hans Clebsch, a professional French horn player with the Cleveland Orchestra and an amateur taxonomist who collected one of the females.

Hosts and Habitat. Hosts unknown; one specimen was collected in dense oak/pine forest.
