Type material.

Holotype, ♀ (RMNH), "Indonesia: N. Sumatra, Ketambe, c 400 m, near N. P. Gn. Leuser, Mal. trap, vi.1994, Y. v. Nierop & C. v. Achterberg, RMNH’95”.

Diagnosis.

Clypeus with rather narrow anchor-shaped black patch medially (Fig. 41); (Fig. 36) and comparatively wide ventrally (Fig. 37); first discal cell of fore wing subhyaline (Fig. 35); hind tibia black; metasoma comparatively slender in dorsal view (Fig. 33); ovipositor with comparatively widely separated serrations (Fig. 40). Differs from the other known species by the rather narrow anchor-shaped black patch of the clypeus, the narrowly interrupted ivory transverse stripe on the pronotum and the dark brown hind tarsus.

Description.

Holotype, ♀, length of body 13.9 mm (of fore wing 9.8 mm).

Head. Antenna with 12 segments and penultimate segment 1.2 times as wide as apical segment in dorsal view (Fig. 38); frons moderately reticulate; vertex coarsely reticulate-punctate (Fig. 42); temple coarsely punctate; malar space densely punctulate; head narrowed behind eyes (Fig. 42); clypeus rather coarsely reticulate and with nearly complete median crest (Fig. 41).

Mesosoma. Length of mesosoma 1.6 times its height (Fig. 34); mesopleuron largely coarsely reticulate-punctate; metapleuron densely punctulate anteriorly and coarsely obliquely rugose posteriorly, with a wide smooth shiny band above it (Fig. 37); pronotum, mesoscutum, scutellum and metanotum coarsely reticulate-punctate, interspaces between punctures of pronotum and metanotum medio-dorsally present, sparsely punctulate and usually 0.5-1.0 times as wide as punctures (Fig. 36); metanotum medially moderately convex and not protruding above level of scutellum (Fig. 34); entire propodeum densely and rather coarsely reticulate-rugose, medially coarser than laterally (Fig. 36).

Wings. Fore wing: vein 2m-cu just postfurcal (Fig. 35).

Legs. Hind basitarsus comparatively slender (Fig. 39).

Metasoma. Metasoma comparatively slender in dorsal view (Fig. 33); basal tergites finely punctate and shiny, with smooth interspaces wider than diameter of punctures (Fig. 33); hypopygium as long as fifth sternite ventrally (Fig. 34); ovipositor with rather widely separated serrations (Fig. 40).

Colour. Black; ivory: pair of wide c-shaped lateral patches on clypeus (resulting in a comparatively narrow black anchor medially; Fig. 41), patch at inner orbita up to top of incision of eye (Fig. 41), shelf of frons anteriorly between antennal sockets, temple largely except narrowly dorsally (Fig. 43), transverse stripe on pronotum (but comparatively narrowly interrupted medially (Fig. 36) and ventrally comparatively wide (Fig. 37)), small patch on pronotum postero-dorsally, elongate patch on mesopleuron antero-dorsally, patch on border of propodeum and metapleuron, small patch near tegula, axilla, lateral patch on metanotum, elongate apical patch on femora, fore femur largely ventrally and elongate basal patch on fore and middle tibiae and outer side of fore tibia subapically largely; metasoma orange red; inner side of fore femur and tibia brown; tarsi largely, veins and pterostigma, dark brown; fore coxa densely silvery setose; first submarginal cell apically, marginal cell and second and third submarginal cells of fore wing dark brown, area below it brown and remainder largely subhyaline (Fig. 35).

Male. Unknown.

Distribution.

Indonesia (Sumatra).

Etymology.

Named in honour of one of the collectors, Yvonne van Nierop (Leiden) for all her collecting efforts in N. Sumatra.
