Description.

Female. Body length: 2.38 mm (n=1). Antenna color: A1 yellow, otherwise dark brown. Body color: completely dark brown. Coxae color: yellow. Leg color (excluding coxae): yellow. Fore wing color: slightly infuscate throughout.

Head. Size of compound eye: approximately 1/2 × 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: with weak, sinuate, transverse ridges 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 weak rugulose-aciculate sculpture. Sculpture of malar space: weakly rugulose 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: large. 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: with abundant areolate sculpture mixed with dense, fine granulae. Sculpture of occipital carina: weakly crenulate throughout. 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 weakly rugulo aciculate sculpture. Sculpture of gena: with weak rugulose sculpture and granulate background sculpture.

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: weakly punctate, smooth posteroventrally. Netrion: present, smooth, linear. Notaulus: present, simple. 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: weakly rugulose mixed with weak granulae. Sculpture of mesoscutellum: granulose. Mesoscutellar profile: mainly flat, anterior and posterior edge at same height or nearly so. Mesoscutellar shape: depressed. Lateral propodeal area: coarsely rugulose. Shape of propodeal anterior spine: elongate, narrow, apex sharply acute. Sculpture of propodeum between anterior spines: longitudinally costate. Sculpture of ventral half of mesepisternum: longitudinally costate on weakly coriaceous background. Sculpture of upper 1/4 of mesopleuron: sparsely 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: narrow, elongate. 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, posterior margin smooth. Sculpture of T3: anterior two-thirds longitudinally costate, otherwise coriaceous. Sculpture of S3-S6: weakly, longitudinally costate mixed with setigerous punctulae. S2 anterior carina: present, cristate, interrupted medially.

Male. Unknown.

Diagnosis.

This species can be distinguished from all other Odontacolus in which the netrion is present and the occipital carina almost touches the orbital carina by the interrupted S2 anterior carina, and the depressed posteromesal area of the mesoscutellum.

Etymology.

This species is named after the African country from which it was collected. The epithet is used as an adjective.
