description: Apsilocera elongata Mitroiu & van Achterberg, sp. n.
(Figs 6, 24)
Type material. Holotype, ♀ (RMNH), “N. VIETNAM: Ninh Binh, Cuc Phuong N.P., nr centre (I), c 225 m, 20.xii.1999 – 10.ii.2000, Mai Phu Quy, RMNH’00”.
Diagnosis. Head transverse in anterior view, without ornamentation; malar space almost half eye height; clypeal margin broadly angulate; each funicular segment with one row of sensilla; clava brown; distal tooth of mandible sharp (Figs 6, 24). Mesosoma arched; fore coxa mainly dark, mid and hind coxae pale yellow, the latter with a small dark spot basally; fore wing hyaline; M about twice S (Fig. 6). Metasoma dorsally brown, slightly paler at base.
Description. Holotype female, body length: 2.75 mm. Colour (Fig. 6): head black, with very slight bluish reflections more visible on face; eyes reddish, ocelli pale yellow; scape, pedicel and anelli reddish-brown, pedicel darker dorsally; funicle and clava brown; mandible brown, teeth darker. Mesosoma as head, but with slight coppery reflections on pronotum, anterior part of mesoscutum, scutellum, axillae and axillulae; wings hyaline; tegula and venation brown; fore coxa mainly dark, mid and hind coxae pale yellow, the latter with a small dark spot basally; trochanters, femora, tibiae and tarsi pale yellow. Metasoma dorsally brown, slightly paler at base; hind margin of distal tergites slightly darker; lateral and ventral sides of metasoma extensively pale yellow basally; ovipositor sheaths brown.
Head transverse in anterior view, without ornamentation; clypeal margin broadly angulate; each funicular segment with one row of sensilla; mandible formula 3:?4, distal tooth of mandible sharp; gena moderately receding towards mouth, not hollowed at mouth corner (Fig. 24); temple short, but not strongly receding towards occiput; occiput emarginate. Relative measurements—length: 28; width: 52; height: 40; POL: 13; OOL: 7; eye height: 28; eye length: 21; malar space: 12; mouth width: 24; distance between clypeal margin and toruli: 29; scape length: 25; pedicel length: 5.5; pedicel width: 3.5; pedicel plus flagellum: 67; F1 length: 7; F1 width: 5; F6 length: 6.5; F6 width: 5; clava length: 17; clava width: 5.5.
Mesosoma arched (Fig. 6); propodeum almost smooth; fore wing with basal cell bare, open below; basal vein pilose; ventral side of costal cell with one row of hairs and some additional hairs in distal part; speculum almost reaching stigmal vein, effaced on ventral side of wing by two irregular rows of hairs; stigma very long, lower edge emarginate (Fig. 6). Relative measurements—length: 61; width: 44; height: 41; mesoscutum length: 27; scutellum length: 22; scutellum width: 21; propodeum length: 10; fore wing length: 145; fore wing width: 66; M: 34; S: 17; P: 38.
Metasoma ovate-acuminate (Fig. 6); ovipositor sheaths barely visible in dorsal view. Relative measurementslength: 86; width: 43; length of first tergite: 15; distance from base of metasoma to tip of hypopygium: 50.
Distribution. Vietnam.
Hosts. Unknown.
Etymology. From the Latin “ elongatus ” (elongated), which refers to the general shape of the body, and of the stigma.
Comments. Apsilocera elongata belongs to a group of species without ornamentation on the vertex. It most closely resembles A. maculata and A. dupla. From both species A. elongata differs in having the gena only slightly receding towards mouth, the clypeal margin broadly angulate (Fig. 24), and an elongated stigma, with lower margin emarginate (Fig. 6).
