Description.

Body length of female: 1.79-2.17 mm (n=20). Body length of male: 1.80-2.36 mm (n=20). Color of head: brown throughout; orange throughout; orange to pale brown. Color of antennal clava (A7-A12): dark brown to black. Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: glabrous. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth. Sculpture of frons below median ocellus: smooth. Sculpture of posterior vertex: smooth. Hyperoccipital carina: absent. Occipital carina medially: interrupted. Length of OOL: less 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: as long as wide. Form of male antennal flagellomeres: filiform, A11 approximately 3.0 × longer than wide. Length of A5 tyloid in male: approximately 0.3 × length of A5.

Color of mesosoma in female: orange throughout; orange to pale brown. Color of mesosoma in male: orange throughout. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth anteriorly, punctate rugulose posteriorly. Sculpture of netrion: smooth. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: smooth throughout. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: absent. Sculpture of mesoscutellum: smooth throughout. Shape of metascutellum: posterior margin rounded, approximately 2.5 × wider than long. Sculpture of metascutellum in female: smooth. Sculpture of metascutellum in male: smooth. Dorsal propodeum in female: shallowly excavate medially, with lateral propodeal carinae widely separated. Sculpture of dorsal propodeum in female: rugose. Sculpture of dorsal propodeum in male: rugose. Median keels on propodeum in female: absent. Mesopleural carina: absent. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth. Color of legs: orange yellow. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: spectral. Setae on R: long, erect, surpassing the margin of the wing. Length of R: approximately as long as r-rs. Length of R1: approximately as long as 2.0 × length of r-rs.

Color of metasoma in female: orange throughout. Color of metasoma in male: orange throughout. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: concentrically striate. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Sculpture of T1 in male: longitudinally striate. Development of longitudinal striae on T2 in female: reaching posterior margin of T2. Sculpture of T3: largely smooth with submedian longitudinal 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 paraglaber in smooth body sculpture and size but can be distinguished by the interrupted occipital carina (occipital carina complete in Calliscelio paraglaber ).

Etymology.

The epithet is an adjective and Latin word for smooth, in reference to the smooth body surface.
