Description.

Body length of female: 2.12-2.51 mm (n=11). Body length of male: 2.05-2.27 mm (n=13). Color of head: black throughout; dark brown. Color of antennal clava (A7-A12): black. Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: with sparse, long setae. IOS/EH: IOS slightly less than EH. Sculpture of ventrolateral frons: smooth to rugulose. Sculpture of frons below median ocellus: largely smooth with sparse fine punctures. Sculpture of posterior vertex: coriaceous. Hyperoccipital carina: absent. Occipital carina medially: weakly developed, irregularly sculptured. Length of OOL: greater than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: coriaceous. Ocular setae: sparse, short. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, as long as wide. Shape of female A6: distinctly wider than long. 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: variably orange to pale brown. Color of mesosoma in male: orange throughout; variably orange to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: largely smooth, granulate ventrally and posteriorly. Sculpture of netrion: rugose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: granulate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: smaller than those along margin of axilla. Sculpture of mesoscutellum: granulate. Shape of metascutellum: posterior margin straight, approximately 3.5 × wider than long. Sculpture of metascutellum in female: rugose anteriorly, smooth posteriorly. Sculpture of metascutellum in male: rugose. Dorsal propodeum in female: deeply excavate medially, with lateral propodeal carinae widely separated, running subparallel to accommodate T1 horn. Sculpture of dorsal propodeum in female: rugulose. 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: coxae to femur white, remainder of the legs pale 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: distinctly shorter than r-rs. Length of R1: approximately as long as 2.0 × length of r-rs.

Color of metasoma in female: orange to pale brown. Color of metasoma in male: T3-T4 orange, otherwise brown. Horn on T1 in female: large and distinct. Sculpture of T1 horn dorsally: smooth to rugulose medially, with V-shaped keels laterally. 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: present on the anterior margin of T2. Sculpture of T3: smooth. 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 latifrons in the female T1 horn, size and habitus but can be easily distinguished by its smooth upper frons and T3.

Etymology.

The specific epithet is to be treated as a noun in apposition, derived from the Latin for “bracelet” and refers to the rim on T1 horn.
