Description.

Female. Body length: 1.65 mm (n=1). Antenna color: completely yellow. Body color: mostly yellow, propodeum, propodeal anterior spines, T1 horn 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: with weak, sinuate, transverse ridges throughout. 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 of vertex: with abundant areolate sculpture mixed with dense, fine granulae sculpture. Sculpture on upper frons below anterior ocellus: covered by sinuate, transverse, fine costae. 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: normal. 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 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: largely smooth, dorsal margin with dense, weak punctulae. Netrion: present, smooth, linear. Notaulus: present, with crenulae that extend completely through depth of furrow. 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: finely granulose. Sculpture of mesoscutellum: with weak, fine, granulate sculpture. 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: elongate, narrow, apex rounded. Sculpture of propodeum between anterior spines: rugulose throughout. Sculpture of ventral half of mesepisternum: weakly coriaceous. Sculpture of upper 1/4 of mesopleuron: densely 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: broad, short. Sculpture of upper portion of T1 horn: longitudinally carinate. Sculpture of posterior portion of T1 horn: transversely carinate. Lateral carinae on T2: present, well-defined. Sculpture of T2: longitudinally costate on coriaceous background. Sculpture of T3: weakly coriaceous. Sculpture of S3-S6: finely, weakly coriaceous. S2 anterior carina: present, cristate, uninterrupted.

Male. Unknown.

Diagnosis.

The species Odontacolus cardaleae belongs to a group having the occipital carina separated from the orbital carina, a well-defined netrion, a central keel on the frons, and well-defined notauli. However, Odontacolus cardaleae is the only species in the group that has a few broad crenulae across the notauli and the antennal scrobes with transverse sinuate ridges. Odontacolus heydoni can be separated from Odontacolus cardaleae by its large ocelli (Fig. 40) and the short distance between the lateral ocellus and occipital carina (approximately 0.5 × the ocellar diameter); Odontacolus cardaleae has small ocelli and the distance between lateral ocellus and occipital carina is approximately 1.5 × the ocellar diameter.

Etymology.

This species is named after Josephine Cardale, former collection manager of Hymenoptera at the ANIC, who collected this species. The epithet is a noun in the genitive case.
