Ooctonus woolleyi Huber , sp. n.

( Figs 5 , 10, 12, 16, 20, 24)

Type material. Holotype ♀ in TAMU, on slide ( Fig. 24 ) with three labels: 1. “ Mexico: Guerrero 6.4 mi. SW. Filo de Cabajjo [sic] 9000' 8.vii.1987, J. Woolley & G. Zolnerowich TAMU Mounted at UCR/ERM by V.V. Berezovskiy 2008 in Canada balsam”. 2. “Univ. Calif. Riverside Ent. Museum UCRCENT 296751”. 3. “ Ooctonus woolleyi Huber & Holotype ”.

Paratypes (23 ♀, 8♂). MEXICO. Guerrero. Same data as holotype (8♂, TAMU, UCRC); 6.6 mi. SW Filo de Caballos, 12.vii.1985, J. Woolley & G. Zolnerowich (7 ♀, CNC, UCRC); 5 mi. SW Filo de Caballos, ca. 8000', 7.vii.1984, J.B.Woolley (1 ♀, CNC); 10.3 km SW Filo de Caballos, 2700m, 13 and 17.vii.1992, R.S. Anderson, oak/pine/fir forest (wet) (3 ♀, CNC). Michoacan. 6 mi. N. Cheran, 8.vii.1985, J. Woolley & G. Zolnerowich (2 ♀, CNC). Oaxaca. 1.4 mi. NE. La Cumbre, 18.vii.1985, J. Woolley, G. Zolnerowich (3 ♀, CNC).

Only the males from the type locality are designated paratypes. Males from elsewhere are not because at least some of them may be males of either O. clebschi or O. zolnerowichi , females of which were collected at some of the same locations as O. woolleyi .

Diagnosis. Flagellum with fl5 and fl6 lacking mps and clava with three clusters of bullae (other species with at most two sets of bullae), the basal cluster with two rows of about 4 bullae each and well separated from the subapical clusters, the latter with 4 or 3 bullae each and clearly separated (Fig. 10) or almost together; head slightly narrower ( Fig. 5 ) than for females of other species.

Among the species North of Mexico, females of O. vulgatus only have several claval bullae, but these are in a single cluster (Huber 2012).

Description. Female. Body length 1400–1500 Μm (critical point dried, n=5). Head except mouthparts and mesosoma very dark brown, almost black, metasoma and procoxa dark brown; antenna dark brown except scape and pedicel laterally and ventrally yellow; petiole and legs except procoxa, yellow with some brown on most of femora dorsally and laterally and on tibiae and apical tarsomere. Head. Width 311–364 (n=3). Vertex without stemmaticum ( Fig. 5 ). Mid ocellus diameter 25–34. Antenna. Measurements (length/width, n= 4 or 5): scape 218– 322/38–42, pedicel 68–80/36–42, fl1 78–130/20–25, fl2 96–154/22–28, fl3 70–115/25–28, fl4 48–76/24–27, fl5 43– 64/25–28, fl6 41–57/26–30, fl7 56–77/31–36, fl8 48–70/33–44, clava 174–210/51–60. Flagellum (Fig. 10) total length 480–743; with 2 mps on fl7, and fl8; fl2 the longest funicle segment; fl1–fl6 length/width ratios (n=5): fl1 3.58– 5.58, fl2 4.14–5.70, fl3 2.84–4.19, fl4 1.92–3.08, fl5 1.71–2.50, fl6 1.60–2.01; clava 3.33–3.59× as long as wide, longer than fl6– fl8 together, with 7 mps and (internally) three clusters of bullae (Fig. 10, inset). Mesosoma. Pronotum ( Fig. 16 ) with collar moderately short, with well defined transverse carina. Mesonotum midlobe with engraved meshes; scutellar seta moderately long, not quite extending posteriorly to medially slightly concave frenal line; axilla reticulate anteriorly, smooth posteriorly; frenum entirely reticulate. Metanotum with dorsellum smooth and lateral lobes smooth except for 1 ( Fig. 16 ) or 2 longitudinal carinae. Propodeum ( Fig. 16 ) smooth between carinae; anterior margin with propodeal stub just lateral to lateral margin of dorsellum; median areole separated from dorsellum by short median carina; plica almost straight, its anterior limit in line with propodeal stub apex, and with a short median branch extending to anterior margin of propodeum. Wings. Fore wing ( Fig. 20 ) length 1388–1862, width 565–778, length/width 2.39–2.61, and longest marginal setae 69–98, about 0.13× as long as greatest wing width (n=5). Hind wing ( Fig. 20 ) length (n=5) 1062–1400, width 66–105, and longest marginal setae 110–150. Metasoma. Petiole shorter than metacoxa + metatrochantellus. Gaster with ovipositor length 506–619 (n=5), 0.99– 1.04× as long as metatibia length (446–628) and projecting slightly beyond gastral apex.

Male. Unidentifiable to species. The males from the same collecting event as the females are assumed to be conspecific with the female. Its genitalia are illustrated ( Fig. 12 ).

Etymology. The species is described in honour of Jim Woolley, a good colleague at Texas A&M University, who collected some of the specimens.

Hosts and Habitat. Primary cloud forest of deciduous trees and conifers.
