Description.

Female. Body length: 1.47 mm (n=1). Antenna color: completely whitish yellow. Body color: head and mesosoma dark brown, head lighter in color than mesosoma, metasoma mostly whitish yellow, T1 dark honey yellow, T2 light honey yellow anteriorly. Coxae color: whitish yellow. Leg color (excluding coxae): whitish yellow. Fore wing color: completely hyaline.

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: weakly granulose throughout. Surface of torular triangle: flat. Development of central keel on frons: present, short (less than 1/3 of frons height). Sculpture on upper frons below anterior ocellus: granulose throughout. Sculpture of malar space: granulose 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: granulate. Sculpture of occipital carina: weakly crenulate throughout. Distance from occipital carina to orbital carina: slightly greater than width of occipital carina. Shape of occipital carina: weakly sinuate medially. Sculpture of occiput: with weak, small granulae. Sculpture of gena: with weak rugulose sculpture and granulate background sculpture.

Mesosoma. Dorsal mesosoma in lateral view: conspicuously flattened. Sculpture of pronotal lateral area: largely smooth, dorsal margin with dense, weak punctulae. Netrion: present, smooth, linear. Notaulus: absent. Length of notaulus: not applicable, notauli absent. Width of notaulus: not applicable, notauli absent. Sculpture of mesoscutum: weakly rugulose, carinae thin in shape. Sculpture of mesoscutellum: rugulose. Mesoscutellar profile: mainly flat, anterior and posterior edge at same height or nearly so. Mesoscutellar shape: flat, not depressed. Lateral propodeal area: longitudinally costate. Shape of propodeal anterior spine: short, broad, apex rounded. Sculpture of propodeum between anterior spines: smooth or largely smooth. Sculpture of ventral half of mesepisternum: smooth or nearly so. Sculpture of upper 1/4 of mesopleuron: smooth. Metapleural sculpture: smooth.

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: smooth. Lateral carinae on T2: absent. Sculpture of T2: weakly coriaceous. Sculpture of T3: coriaceous. Sculpture of S3-S6: finely, weakly coriaceous. S2 anterior carina: absent.

Male. Unknown.

Diagnosis.

This species can be distinguished from all other Odontacolus species lacking notauli by the conspicuous dorsoventrally depressed mesosoma.

Etymology.

This species is named after the dipteran expert Dr Evert Schlinger, collector of this species. The epithet is a noun in the genitive case.
