Description.

Body length of female: 3.35 mm (n=1). Color of head: brown throughout. Color of antennal clava (A7-A12): dark brown to black. Shape of head: subglobose. Central keel of frons: present. Setation of upper frons: with dense, short setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth with sparse punctures. Sculpture of frons below median ocellus: granulate to finely punctate. Sculpture of posterior vertex: punctate rugose. Hyperoccipital carina: absent. Occipital carina medially: complete, strongly crenulate throughout. Length of OOL: greater than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: smooth. Ocular setae: sparse, short. A4 in female: as long as A3. A5 in female: shorter than A3, distinctly longer than wide. Shape of female A6: distinctly longer than wide.

Color of mesosoma in female: dark brown. Sculpture of dorsal pronotal area: areolate. Sculpture of lateral pronotal area: smooth dorsally, rugulose ventrally. Sculpture of netrion: rugulose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: densely punctate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: as large as those along margin of axilla. Sculpture of mesoscutellum: densely punctate. Shape of metascutellum: posterior marging rounded, approximately 4.0 × wider than long. Sculpture of metascutellum in female: rugose. Dorsal propodeum in female: not excavate medially, lateral propodeal carinae meeting anteromedially. Sculpture of dorsal propodeum in female: rugose. Median keels on propodeum in female: present. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: largely smooth, rugose ventrally. Color of legs: orange yellow. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: nebulose, strongly pigmented. Setae on R: long, erect, surpassing the margin of the wing. Length of R: distinctly shorter than r-rs. Length of R1: greater than 3.0 × length of r-rs.

Color of metasoma in female: dark brown. Horn on T1 in female: absent. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Development of longitudinal striae on T2 in female: reaching posterior margin of T2. Sculpture of T3: smooth. Shape of T6 in female: short, slightly longer than wide. Sculpture of S3: smooth.

Diagnosis.

This species is most similar to Calliscelio rugicoxa with which it shares the characters of the hairy compound eyes and the median keels on propodeum in female. It can be distinguished by its smooth hind coxa and the absence of a T1 horn in the female.

Etymology.

The specific epithet means "with two teeth," refering to the median keels of propodeum of the species and should be treated as a noun in apposition.
