Genus: Dirhinus
Name
Dirhinus auratus Ashmead, 1905 – Wikispecies link – Pensoft Profile
- Dirhinus auratus Ashmead, 1905: 402 (♀, lectotype (selected by Bouček & Narendran, 1981), Philippines (Manila) (USNM) (examined)).
- Dirhinus pambaeus Mani & Dubey (in Mani et al.), 1974[1]: 33–36 (♂, holotype, India (Kerala) (USNM) (examined) (synonymised by Bouček and Narendran 1981[2] with Dirhinus auratus Ashmead)).
- Dirhinus circinus Husain & Agarwal, 1981: 182. (♀, India (Aligarh) (ZDAMU) (examined) (synonymised with Dirhinus auratus Ashmead by Narendran 1989[3])).
Material
1 ♀ (RMNH), “Vietnam: Ninh Thuân, Núi Chúa N. P., 90–150 m, Northeast part, 23–30.v.2007, C. v. Achterberg & R. de Vries, RMNH’07”; 1 ♀ (IEBR), “S. Vietnam: Dóng Nai, Cát Tiên N. P., Dong trail, Malaise traps, c. 100 m, 1–8.iv.2007, Mai Phu Quy & Nguyen Tanh Manh, RMNH’07”; 1 ♀ (BPBM), “Vietnam, 20 km S of Dalat, 1300 m, 12.ix.1960, Gressitt”; 1 ♀ (BPBM), “Vietnam, Ap Hung Lam, 21 kms N.W. of Dilinh, 1100 m, ix–x.1960, Yoshimoto”.
Diagnosis
This species comes near Dirhinus anthracia Walker in the key to species by Bouček and Narendran (1981)[2], but differs from Dirhinus anthracia in having: 1) each horn in dorsal view at anterior ocular line slightly narrower than scrobal gap (in Dirhinus anthracia each horn in dorsal view at level with anterior eye margin broader than scrobal gap); 2) median areola of propodeum elongate with almost parallel sides (in Dirhinus anthracia median aeola of propodeum with convex sides, shortly oval); 3) scutellum without an impunctate strip (in Dirhinus anthracia scutellum anteriorly with an impunctate strip); 4) striate area on T1 narrower than long, with few striae and its hind margin produced in middle (in Dirhinus anthracia striate area of T1 nearly straight, the area subquadrate or even broader than long) and 5) parascrobal space usually with less than two compete rows of punctures between pre-orbital carina and scrobal margin (in Dirhinus anthracia narrow space between eye and lower part of scrobe with pre-orbital carina separated from scrobes by fully 2 rows of punctures).
Description
♀♂, length of body 3.1–4.1 mm.
Colour. General body colour black with antenna, tegulae, fore and mid legs (except coxae) mainly reddish.
Head. Head below each horn without distinct additional teeth; facial edge of scrobe sinuate, apex of each horn with distinct notch; each horn in dorsal view at anterior ocular line slightly narrower than scrobal gap; parascrobal area in ♀ hardly one-third as broad as scrobal cavity, with only one compete row of punctures between pre-orbital carina and scrobal edge; head in lateral view about 0.7 × wider than high (Fig. 75); genal length subequal to short diameter of eye; pedicel slightly longer than second flagellar segment; clava nearly twice as long as wide.
Mesosoma. Mesosoma not flattened; scutellum extensively punctate, without impunctate strip; median areola of propodeum elongate with almost parallel sides.
Wings. Fore wing pilosity usually distinct.
Legs. Hind tibia without distinct external additional carina.
Metasoma. Petiole of ♀ with an area of four carinae about 1.5 × as broad as long, with fewer striae apically than in middle.
Host
Dacus sp. (Diptera: Tephritidae).
Distribution
Vietnam, India, Pakistan, Sri Lanka, Thailand, Laos, China (Taiwan) and Philippines (Bouček and Narendran 1981[2]; Narendran 1989[3]).
