Etymology. The specific name, angustitemple, is Latin meaning “narrow temple”, in reference to the narrow temple of female of this species.
Type material. Holotype: ♀ (BLKU), emerged on 6 May 2008 from a gall of Celticecis japonica on Celtis sinensis var. japonica collected by J. Yukawa and K. Matsuo on 6 October 2007 from Amagouchi, Nima, Oda, Shimane, Japan. Paratype: 1 ♀, collected by T. Mita on 14 October 2006 from Musashino, Fukaya, Saitama, Japan (BLKU).
Description. Female. Body length excluding ovipositor sheath 3.9–4.3 mm. Head dark green. Scape yellow; pedicel yellow; all flagellomeres black. Mesosoma dark green with violet reflection. Fore wing with an infumate streak. Fore and mid coxae yellow; base of hind coxa concolorous with mesosoma; all femora and tibiae yellow. Metasoma dark green with violet reflection (Fig. 1d).
Head 2.0–2.2× as wide as long in dorsal view; temple narrow, 0.03–0.04× as long as dorsal length of eye; POL 2.2× OOL; OOL 0.9–1.0× OD. Head 1.2–1.3× as wide as high in frontal view (Fig. 11a); eyes separated by 0.7–0.8× their height; malar space narrow, 0.2× height of eye; mouth 2.8–3.0× malar space; gena straight; clypeus with apical margin produced, truncate medially. Antenna not clearly clavate (Fig. 5g); scape 0.7× as long as height of eye, just reaching ventral margin of anterior ocellus; combined length of pedicel and flagellum 1.3–1.4× width of head; pedicel 2.2× as long as wide; anellus 1.0–1.1× as wide as long; F1 1.4–1.7× as long as wide, shorter than pedicel; F2–F5 1.3–1.5× as long as wide; F6 1.3–1.4× as long as wide; F7 1.2–1.3× as long as wide; each funicular segment bearing longitudinal sensilla arranged in two rows; C3 with a tuft of micropilosity beneath.
Mesosoma 1.6–1.9× as long as wide; mesoscutum (Fig. 11b) with large piliferous punctures; sculpture on mesoscutum in anterior half transversely reticulate; notaulus shallow; scutellum (Fig. 11c) 1.2–1.4× as long as wide, with large piliferous punctures; dorsellum without median carina; propodeum (Fig. 11d) reticulate; lower mesepimeron 1.1–1.2× as long as wide. Fore wing 2.5–2.6× as long as wide (Fig. 24d); costal cell 11.5× as long as wide, on upper surface with a setal row in distal half, on lower surface with a complete setal row and scattered setae; basal cell closed, hairy; cubital setal line present; basal setal line present; speculum closed below; relative lengths of marginal vein: postmarginal vein: stigmal vein=6.6: 1.7: 1.0. Hind coxa 1.9–2.1× as long as wide, with dorsal carina extending 1/4 length; dorsal surface of hind coxa bare in basal half; hind femur 3.7–3.9× as long as wide; hind tibia with longer spur 1.1–1.2× as long as width of hind tibia, 0.4× length of basitarsus; shorter spur 0.6–0.7× length of longer spur.
Metasoma as long as mesosoma plus head; posterior margin of metasomal tergum five incised; tip of hypopygium situated at 0.6 length of metasoma; ovipositor sheath as long as metasoma, 1.8–2.0× as long as hind tibia.
Male. Unknown.
Distribution. Japan (Honshu).
Host information. Torymus angustitemple is an ectoparasitoid of Celticecis japonica Yukawa and Tsuda (Diptera: Cecidomyiidae) that induces galls on Celtis sinensis Pers. var. japonica (Planch.) Nakai (Cannabaceae) (gall photo: fig. 26c, C–202 of Yukawa & Masuda 1996).
Remarks. Females of T. angustitemple are similar to T. macrops Matsuo by having the following characters: fore wing with infumate streak; temple narrow; malar space 0.2× height of eye; pedicel 2.2× as long as wide; F1 shorter than pedicel; mesoscutum and scutellum with large piliferous punctures. However, females of T. angustitemple can be distinguished from T. macrops by having the following features: POL 2.2× OOL (1.7–1.9× OOL in T. macrops); hind coxa with dorsal carina extending 1/4 length (with dorsal carina basally in T. macrops); ovipositor sheath 1.8–2.0× as long as hind tibia (2.6× as long as hind tibia in T. macrops).
