Description.

Body length of female: 1.83-2.27 mm (n=20). Body length of male: 1.94-2.19 mm (n=20). Color of head: variably pale yellow to brown; reddish orange throughout. Color of antennal clava (A7-A12): A7-A9 brown, A10-A12 white; A7 brown, remainder orange. Shape of head: subglobose. Central keel of frons: present. Setation of upper frons: with sparse, long setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth to coriaceous. Sculpture of frons below median ocellus: coriaceous. Sculpture of posterior vertex: transversely striate. Hyperoccipital carina: present. 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: as long as 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: greater than 0.5 × length of A5.

Color of mesosoma in female: variably yellow to pale brown; reddish orange throughout. Color of mesosoma in male: orange throughout; variably orange to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth throughout. Sculpture of netrion: smooth. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: coriaceous. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: as large as those along margin of axilla. Sculpture of mesoscutellum: smooth with sparse fine punctures. Shape of metascutellum: posterior margin rounded, approximately 3.0 × wider than long. Sculpture of metascutellum in female: smooth with a longitudinal, median carina. Sculpture of metascutellum in male: smooth with longitudinal, median carina. Dorsal propodeum in female: not excavate medially, lateral propodeal carinae meeting anteromedially. Sculpture of dorsal propodeum in female: rugose with one or two longitudinal keels lateral median keel. Sculpture of dorsal propodeum in male: rugose with one or two longitudinal keels lateral median keel. 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 throughout; pale yellow throughout. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: spectral. Setae on R: short, decumbent, hardly exceeding the margin of the wing. Length of R: distinctly shorter than r-rs. Length of R1: greater than 3.0 × length of r-rs.

Color of metasoma in female: orange throughout; variably orange to pale brown. Color of metasoma in male: variably orange to pale brown. Horn on T1 in female: absent. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Sculpture of T1 in male: longitudinally striate. Development of longitudinal striae on T 2 in female: reaching the middle of T2 medially. Sculpture of T3: smooth. Shape of T6 in female: short, wider than long. Sculpture of S3: smooth.

Diagnosis.

This species is most similar to Calliscelio brachys and Calliscelio suni . It can be separated from Calliscelio brachys by the percurrent notaulus, and from Calliscelio suni by the spectral Rs+M and the presence of a central keel on the frons.

Etymology.

The epithet is used as a noun in apposition derived from the Latin word for ivory, in reference to the white A11-A12 of the female antennae.
