Description.

Body length of female: 2.31-2.53 mm (n=8). Body length of male: 2.24-2.26 mm (n=4). Color of head: orange throughout. Color of antennal clava (A7-A12): dark brown to black. Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: with dense, short setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: granulate. Sculpture of frons below median ocellus: granulate. Sculpture of posterior vertex: granulate. Hyperoccipital carina: absent. Occipital carina medially: complete, weakly crenulate throughout. Length of OOL: less than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: granulate. Ocular setae: dense, 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: greater than 0.5 × length of A5.

Color of mesosoma in female: orange throughout. Color of mesosoma in male: orange throughout. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: largely smooth, granulate ventrally and posteriorly. Sculpture of netrion: rugulose. 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 4.0 × wider than long. Sculpture of metascutellum in female: rugose. 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: rugose. Sculpture of dorsal propodeum in male: 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: orange yellow. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: nebulose, weakly pigmented. 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 with pale brown patch on T1, T2 and T6. Color of metasoma in male: orange with pale brown patch on T2 and T5-T7. Horn on T1 in female: large and distinct. Sculpture of T1 horn dorsally: longitudinally 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 the middle of T2 medially; reaching posterior margin of T2. Sculpture of T3: smooth. Shape of T6 in female: distinctly elongate, approximately 2.0 × longer than wide. Sculpture of S3: smooth.

Diagnosis.

This species is most similar to Calliscelio telum in hairy compound eyes and habitus but can be distinguished by its rugulose netrion and longitudinally striate T1 horn.

Etymology.

The adjectival specific epithet refers to the sculpture of the body.
