Description.

Female. Body length: 1.54 - 1.83 mm (n=2). Antenna color: completely yellow. Body color: mostly yellow, T1 horn and T4-T6 dark brown. Coxae color: yellow. Leg color (excluding coxae): yellow. Fore wing color: completely hyaline.

Head. Size of compound eye: reduced, approximately less than or equal to 1/3 × height of head. Head shape in lateral view: lower head elongate and broad at mouth, head appearing elongate and somewhat thin. Sculpture of antennal scrobe: coriaceous throughout. Surface of torular triangle: flat. Development of central keel on frons: present, elongate (equal to or greater than 1/3 × height of frons), but not reaching anterior ocellus. Sculpture on upper frons below anterior ocellus: with sparse, transverse costae mixed with weak, dense granulae. Sculpture of malar space: coriaceous throughout, without fan-like striae. Furrow at lateral portion of antennal scrobe: absent. Mesal surface of vertex: flat to weakly convex. Size of lateral ocelli: normal. Distance between lateral ocellus and occipital carina: 0.5 –1.2× maximum ocellar diameter. Lagrimal: absent or minute. Length of OOL: less than or equal to 1/3 × width of ocellus. Sculpture of vertex: granulate. Sculpture of occipital carina: largely simple, at most with sparse weak crenulae medially. Distance from occipital carina to orbital carina: at least 2 × width of occipital carina. Shape of occipital carina: simply arcuate medially. Sculpture of occiput: with weak, small granulae. Sculpture of gena: granulose.

Mesosoma. Dorsal mesosoma in lateral view: convex. Sculpture of pronotal cervical area: with small (at most as large as crenulae on anterior edge of mesoscutum), well-defined foveae. Sculpture of pronotal lateral area: coriaceous. Netrion: present, smooth, well developed, sub-obovate. Notaulus: present, with crenulae that extend completely through depth of furrow. Length of notaulus: approximately less than or equal to 1/3 of length of mesoscutum. Width of notaulus: narrow (notaulus width less than or equal to half the width of tegula). Sculpture of mesoscutum: finely granulose. Sculpture of mesoscutellum: with weak, fine, granulate sculpture. Mesoscutellar profile: mainly flat, anterior and posterior edge at same height or nearly so. Mesoscutellar shape: flat, not depressed. Lateral propodeal area: densely, finely rugulose. Shape of propodeal anterior spine: short, broad, apex subtriangular. Sculpture of propodeum between anterior spines: smooth or largely smooth; longitudinally costate. Sculpture of ventral half of mesepisternum: weakly coriaceous. Sculpture of upper 1/4 of mesopleuron: densely longitudinally costate across entire width. Metapleural sculpture: mainly with weak coriaceous sculpture, lower 1/3 without longitudinal costae.

Wings. Stigmal vein: present, elongate, narrow. Campaniform sensilla at distal area of stigmal vein: present.

Metasoma. Shape of T1 horn: broad, short. Sculpture of upper portion of T1 horn: longitudinally carinate. Sculpture of posterior portion of T1 horn: longitudinally carinate. Lateral carinae on T2: present, poorly defined. Sculpture of T2: longitudinally costate on coriaceous background. Sculpture of T3: anterior half weakly longitudinally costate, otherwise coriaceous, microsculpture strongest medially. Sculpture of S3-S6: finely, weakly coriaceous. S2 anterior carina: present, cristate, uninterrupted.

Male. Unknown.

Diagnosis.

This is the only species of Odontacolus that has the compound eyes unusually small, approximately 1/3 of the height of the head.

Etymology.

This species is named after our friend and colleague, the chalcid specialist and great insect collector Dr John Noyes from the Natural History Museum, London. The epithet is a noun in the genitive case.

Material examined.

Holotype female: INDIA: Karnataka St., Bannerghatta National Park, 5.XI.1979, Bouček & Noyes, OSUC 237932 (deposited in BMNH). Paratype: INDONESIA: 1 female, OSUC 237931 (CNCI).

Comments.

The holotype has the left legs separate and glued to the point. Otherwise it is in good condition. The paratype in perfect condition: it has the metasoma completely honey yellow and the remainder of the body, including the legs, yellow.
