Description.
Female. Body length: 1.25 mm (n=2). Antenna color: completely yellow. Body color: completely dark brown. 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: largely smooth, with sparse coriaceous sculpture close to compound eyes. Sculpture of malar space: largely smooth, coriaceous sculpture present near compound eyes (somewhat weak). Furrow at lateral portion of antennal scrobe: absent. Mesal surface of vertex: flat to weakly convex. Size of lateral ocelli: small. 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: coriaceous. Sculpture of occipital carina: largely simple, at most with sparse weak crenulae medially. Distance from occipital carina to orbital carina: slightly greater than width of occipital carina. Shape of occipital carina: simply arcuate medially. Sculpture of occiput: with weakly rugulo aciculate sculpture. Sculpture of gena: coriaceous dorsally, otherwise smooth.
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: largely smooth, dorsal margin with dense, weak punctulae. 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: coriaceous. Sculpture of mesoscutellum: weakly coriaceous. 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. Sculpture of ventral half of mesepisternum: smooth or nearly so. Sculpture of upper 1/4 of mesopleuron: densely longitudinally costate across half width. Metapleural sculpture: smooth.
Wings. Stigmal vein: present, elongate, narrow. Campaniform sensilla at distal area of stigmal vein: present.
Metasoma. Shape of T1 horn: narrow, short. Sculpture of upper portion of T1 horn: largely smooth, with sparse longitudinal carinae. Sculpture of posterior portion of T1 horn: largely smooth, with sparse longitudinal carinae. 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: mainly smooth, with sparse, setigerous punctulae. S2 anterior carina: present, cristate, uninterrupted.
Male. Unknown.
Diagnosis.
This species can be distinguished from all other Odontacolus species by the combination of the completely smooth gena, the well-defined netrion, the presence of notauli, and the confused, dense rugulose sculpture of the lateral propodeum.
Etymology.
This species is named after the island from which the species was collected, Madagascar. The epithet is used as an adjective.
