Description.

Female. Body length: 1.39 mm (n=1). Antenna color: A1 yellow, otherwise dark brown. Body color: completely yellow. 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: largely smooth ventrally, sparsely granulate ventrally. Surface of torular triangle: slightly bulging. 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. Shape of medial area of vertexmedial area 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: granulate. 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 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: upper 1/3 granulose, lower 1/3 with transverse foveae, otherwise smooth. 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: weakly rugulose mixed with granulate sculpture. Mesoscutellar profile: elevated, anterior margin higher than posterior. Mesoscutellar shape: flat, not depressed. Lateral propodeal area: densely, finely rugulose. Shape of propodeal anterior spine: elongate, narrow, apex rounded. Sculpture of propodeum between anterior spines: smooth or largely smooth. Sculpture of ventral half of mesepisternum: longitudinally costate on weakly coriaceous background. Sculpture of upper 1/4 of mesopleuron: densely longitudinally costate across half width. Metapleural sculpture: mainly smooth, lower third sparsely longitudinally carinate.

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: largely smooth, with sparse longitudinal carinae. Lateral carinae on T2: present, well-defined. Sculpture of T2: largely coriaceous, smooth mesally. Sculpture of T3: smooth mesally, otherwise weakly coriaceous. Sculpture of S3-S6: S3 weakly coriaceous, S4-S6 mainly smooth with few, sparse, setigerous punctulae sculpture. S2 anterior carina: present, cristate, interrupted medially.

Male. Unknown.

Diagnosis.

The species Odontacolus baeri is very similar to Odontacolus africanus and Odontacolus anningae but can be distinguished from them by the absence of the S2 anterior carina. Both Odontacolus africanus and Odontacolus anningae have a clearly divided S2 anterior carina, but Odontacolus anningae is mainly yellow in body color, contrasting with Odontacolus africanus which is completely dark brown.

Etymology.

This species is named after the great British fossil hunter Mary Anning. The epithet is a noun in the genitive case.
