Description.

Body length of female: 1.92-2.30 mm (n=10). Color of head: black throughout; reddish orange throughout. Color of antennal clava (A7-A12): black; A7 orange, remainder dark brown to black. Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: with sparse, short setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth with sparse punctures. Sculpture of frons below median ocellus: largely smooth with sparse fine punctures. Sculpture of posterior vertex: coriaceous; largely smooth with irregular fine sculpture. Hyperoccipital carina: absent. Occipital carina medially: complete, weakly crenulate throughout. Length of OOL: less than 0.5 × ocellar diameter; greater than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: smooth. Ocular setae: absent. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, distinctly longer than wide. Shape of female A6: slightly longer than wide.

Color of mesosoma in female: orange throughout; black throughout; variably yellow to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth throughout. Sculpture of netrion: smooth. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: coriaceous; coriaceous anteriorly, smooth with sparse fine punctures posteriorly. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: as large as those along margin of axilla. Sculpture of mesoscutellum: smooth with sparse fine punctures. Shape of metascutellum: posterior margin straight, approximately 4.0 × wider than long. Sculpture of metascutellum in female: smooth with a longitudinal, median carina. 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: absent. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth. Color of legs: pale yellow throughout. 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: approximately as long as 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: weakly developed. Sculpture of T1 horn dorsally: smooth. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Development of longitudinal striae on T2 in female: reaching the middle of T2 medially. Sculpture of T3: smooth with longitudinal submedian striae. Shape of T6 in female: short, slightly longer than wide. Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

This species is most similar to Calliscelio levis but can be distinguished by the foveolae of the scutoscutellar sulcus between the notauli which are as large as those along the margin of axilla and that A4 is distinctly shorter than A3.

Etymology.

The epithet is an adjective, derived from the Latin word for small hole, in reference to the sculpture of the scutoscutellar sulcus.
