TYPE MATERIAL — Holotype female ( MNHN), Papua New Guinea. Province Madang, Mount Wilhelm , 1700 m, -5.759269 145.2356, 1-2/xi/2012, Valeba, Tulei, Novotny, Leponce, Plot 1, understory; Malaise, MAL-MW1700A-08/16- d08, P2175-8771 .

Nepolynema wilhelmense female. 12, antenna, lateral view; 13, wings; 14, gaster surface, lateral view; 15, ovipositor. Scale bars = 500 μm.

FIGURES 16-21

Nepolynema grande (Taguchi) . 16, head,anterior view; 17, head,lateral view, 18, head,ventral view; 19, mouthparts,ventral view; 20, mesosoma, dorsal view; 21, mesosoma, lateral view. Scale bars: 16, 17, 18, 20, 21 = 50 μm, 19 = 20 μm.

DIAGNOSIS — Mesoscutum with the ductules radiating from each small scutellar gland (Figure 5) and the glands separated from each other by about twice their length, vertex shiny, almost uniform dark brown and the same color as the trabecula, mesoscutum shiny with sculpture faint, and ovipositor about two-thirds length of metatibia. It is most similar to N. kasparyani Triapitsyn but differs in having fl1 only very slightly longer than the pedicel (fl1 1.3× as long as the pedicel in N. kasparyani ), the toruli are slightly separated from the transverse trabecula (touching trabecula in N. kasparyani ), and the scutellar glands are closer to each other and to the campaniform sensilla (wider apart in N. kasparyani ).

DESCRIPTION — FEMALE: Length 1360 μm (holotype). Color. Body mainly dark brown and shiny ( Figure 1); face yellow brown, vertex and trabeculae black, scape brown, radicle, pedicel, fl 1 -fl 4, face, petiole, fore leg, and trochanters of middle and hind legs yellow brown. Head. Width 445 (paratype); face with toruli separated slightly from transverse trabecula (Figure 3); mid ocellus small, its greatest diameter 20. Antenna. Fl 5 with 1 mps and fl6 with 2 mps, clava with 9 mps. Length/width measurements (n=1, paratype): scape 252/70, pedicel 95/52, fl 1 98/31, fl 2 201/33, fl 3 199/34, fl 4 117/39, fl 5 98/44, fl6 108/47, clava 420/89. Mesosoma. Entire mesosoma mostly smooth and shiny. Scutellum with extremely faint reticulate sculpture and a shallow longitudinal median furrow; scutellar glands separated from each other about by 2× their maximum length, each gland compact—a short, curved line with about 10 radiating ductules. Wings. Fore wing length 1848 (n=1), width 518, length/width 3.57, longest marginal setae 372. Hind wing length (n=1) 1150, width 26, longest marginal setae 206. Metasoma. Petiole and gaster smooth and shiny. Ovipositor sheath length 422, 0.69× metatibia length (615).

MALE: Unknown.

ETYMOLOGY — From alpestre, Latin for “of high mountains”, referring to the fact that the specimens were collected at a fairly high elevation.
