Description.

Female. Body length: 1.88 mm (n=1). Antenna color: A1 yellow, otherwise dark brown. Body color: head yellow, mesosoma mostly yellow, mesoscutum anteromesally and posterolaterally dark honey yellow, metasoma mainly dark honey yellow, sublateral areas of T3 yellow. Coxae color: yellow. Leg color (excluding coxae): 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: smooth 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: granulose throughout. Sculpture of malar space: with fan-like striae, striae extending into antennal scrobe. 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: less than 0.5 × maximum ocellar diameter. Lagrimal: conspicuously present (approximately 0.4 × of malar sulcus length). 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 weakly rugulo aciculate sculpture. 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: smooth or nearly so. 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: anterior half coriaceous, otherwise densely granulose. Sculpture of mesoscutellum: granulose. 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: elongate, narrow, apex rounded. Sculpture of propodeum between anterior spines: transversely costate. Sculpture of ventral half of mesepisternum: weakly coriaceous. Sculpture of upper 1/4 of mesopleuron: densely longitudinally costate across half width. Metapleural sculpture: mainly with weak coriaceous sculpture, lower 1/3 with sparse longitudinal carinae.

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 third weakly longitudinally costate, otherwise coriaceous. Sculpture of S3-S6: finely, weakly coriaceous. S2 anterior carina: present, cristate, uninterrupted.

Male. Unknown.

Diagnosis.

This species can be easily distinguished from all other Odontacolus species based on the large and conspicuous lagrimal in combination with the occipital carina which is almost touching the orbital carina.

Etymology.

This species is named after the Genting Tea Estate, Malaysia from where the species was collected. The epithet is used as an adjective.
