(Figs 4, 22)
Type material. Holotype, ♀ (RMNH), “S. VIETNAM: Lam Dong, Bidoup Nuiba N.P., nr Da Lat, Mal. trap 19-23, 1680– 1700 m, 12–19.x.2005, C. v. Achterberg & R. de Vries, RMNH’05”.
Diagnosis. Head slightly transverse in anterior view, with a row of teeth near each eye, the tooth near eye being the largest; clypeal margin with a narrow projection, which is slightly emarginate in the middle (Fig. 22); each funicular segment with one row of sensilla; clava brown (Fig. 4); distal tooth of mandible rounded (Fig. 22). Mesosoma only slightly arched dorsally; fore coxa mainly dark, mid and hind coxae pale yellow, the latter with a small dark spot basally; fore wing hyaline (Fig. 4). Metasoma dorsally brown except small pale basal depression.
Description. Holotype female, body length: 2.5 mm. Colour (Fig. 4): head dark blue green; eyes reddish, ocelli whitish; scape orange, paler proximally and ventrally; pedicel orange, dorsally brown; flagellum uniformly brown; mandible brown, teeth blackish. Mesonotum and propodeum dark bluish, rest of mesosoma dark olive green; wings hyaline; tegula orange; venation light brown; fore coxa mainly dark, mid and hind coxae pale yellow, the latter with a small dark spot basally; femora and tibiae pale yellow, tarsi slightly darker, their tips brown. Metasoma dorsally dark brown, somewhat paler towards apex, with a small yellowish depression at base of the first tergite; laterally and ventrally light brown to yellow; ovipositor sheaths brown.
Head slightly transverse in anterior view, with a row of teeth near each eye, the tooth near eye being the largest; vertex high, in anterior view distinctly arched between posterior ocelli; gena moderately receding towards mouth, not hollowed at mouth corner (Fig. 22); temple virtually absent; occiput straight; clypeal margin with a narrow projection, which is slightly emarginate in the middle (Fig. 22); each funicular segment with one row of dense sensilla (Fig. 4); distal tooth of mandible rounded (Fig. 22). Relative measurements—length: 25; width: 54; height: 46; POL: 13; OOL: 16; eye height: 22; eye length: 16.5; malar space: 11; mouth width: 27; distance between clypeal margin and toruli: 30; scape length: 25; pedicel length: 5; pedicel width: 3; pedicel plus flagellum: 68; F1 length: 7; F1 width: 4.5; F6 length: 7; F6 width: 5; clava length: 18; clava width: 5.
Mesosoma only slightly arched dorsally (Fig. 4); mesoscutum almost flat, central part with reticulation meshes very large; propodeum almost smooth; fore wing with basal cell bare except 3–5 scattered hairs, open below; basal vein pilose; ventral side of costal cell with one complete row of hairs, a second partially complete row, and a patch of hairs in distal part; speculum reaching parastigma; stigma elongated (Fig. 4). Relative measurements—length: 56; width: 43; height: 33; mesoscutum length: 23; scutellum length: 19; scutellum width: 21; propodeum length: 7; fore wing length: 135; fore wing width: 60; M: 34; S: 15; P: 36.
Metasoma short ovate (Fig. 4); dorsal side of first tergite with a small triangular depression at base; ovipositor sheaths slightly visible in dorsal view. Relative measurements—length: 72; width: 46; length of first tergite: 20; distance from base of metasoma to tip of hypopygium: 30.
Distribution. Vietnam.
Hosts. Unknown.
Etymology. From the Latin “ dentatus ” (with teeth), which refers to the multiple teeth present on the head.
Comments. Apsilocera dentata belongs to a group of species having distinct teeth in the upper part of the head. This species most closely resembles A. cornuta, but differs in many respects, the most obvious being the presence of a row of teeth on each side of the vertex, instead of only one tooth (Fig. 22).
