Description.

Body length of female: 1.42-1.74 mm (n=20). Color of head: orange throughout. Color of antennal clava (A7-A12): A7, A8 brown, A9-A12 white to pale yellow. 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 to granulate. Sculpture of frons below median ocellus: smooth to granulate. Sculpture of posterior vertex: rugose. Hyperoccipital carina: absent. Occipital carina medially: interrupted. Length of OOL: less than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: largely smooth with small granulate area. Ocular setae: sparse, short. A4 in female: as long as A3. A5 in female: shorter than A3, distinctly longer than wide. Shape of female A6: distinctly longer than 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 throughout. 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 rounded, approximately 3.0 × 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; smooth to rugulose. Median keels on propodeum in female: absent. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: largely smooth, rugose ventrally. 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: variably orange to pale brown. Horn on T1 in female: absent. Sculpture of posterior margin of T1 in female: longitudinally striate throughout; striate rugose. Development of longitudinal striae on T2 in female: reaching the middle of T2 medially; present on the anterior margin of T2. Sculpture of T3: smooth. Shape of T6 in female: short, wider than long. Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

This species is most similar to Calliscelio extenuatus and Calliscelio suni in size and habitus. It can be separated from Calliscelio extenuatus by the interrupted occipital carina and the elongate A6, and from Calliscelio suni by the hairy compound eyes.

Etymology.

The epithet is used as a noun in apposition derived from the Latin word for wrinkle, in reference to the rugose posterior vertex.
