Description.

Body length of female: 1.76-2.15 mm (n=20). Color of head: black throughout; variably brown to black. 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 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: sparse, short. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, as long as wide. Shape of female A6: as long as wide.

Color of mesosoma in female: orange throughout; variably orange to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth anteriorly, granulate 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 4.0 × wider than long. Sculpture of metascutellum in female: rugose. Dorsal propodeum in female: shallowly excavate medially, with lateral propodeal carinae widely separated. Sculpture of dorsal propodeum in female: rugose. Median keels on propodeum in female: absent. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: largely smooth with a row of foveae along mesopleural carina. Sculpture of ventral metapleural area: largely smooth, rugose ventrally. Color of legs: orange throughout. 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: variably orange to pale brown. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: rugulose. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. 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: smooth.

Diagnosis.

This species is most similar to Calliscelio bisulcatus and Calliscelio virga in the hairy compound eyes, size and habitus. It can be separated from Calliscelio bisulcatus by the granulate mesoscutellum and the broad and short metascutellum, and from Calliscelio virga by the rugose metascutellum and the rugulose T1 horn in the female.

Etymology.

The epithet is used as a noun in apposition derived from the Latin word for mat or rug, in reference to the rugulose T1 horn in female.
