Shape of female A6: distinctly wider than long. Form of male antennal flagellomeres: filiform, A11 approximately 2.5 × longer than wide. Length of A5 tyloid in male: greater than 0.5 × length of A5.

Color of mesosoma in female: orange throughout; black throughout; orange to pale brown. Color of mesosoma in male: orange throughout; dark brown throughout; black throughout. Sculpture of dorsal pronotal area: smooth. Sculpture of lateral pronotal area: smooth throughout; smooth anteriorly, granulate posteriorly. Sculpture of netrion: smooth. Notaulus: abbreviated, at most reaching middle of mesoscutum. Sculpture of mesoscutum: coriaceous. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: smaller than those along margin of axilla. Sculpture of mesoscutellum: coriaceous; anterior half granulate, posterior half smooth. Shape of metascutellum: posterior margin rounded, approximately 3.0 × wider than long. Sculpture of metascutellum in female: with short longitudinal carinae.

Sculpture of ventral metapleural area: largely smooth with an oblique carina. Color of legs: pale yellow throughout; white 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: greater than 3.0 × length of r-rs.

Color of metasoma in female: dark brown; orange throughout; yellow throughout. Color of metasoma in male: orange throughout; brown throughout. Horn on T1 in female: absent; weakly developed. Sculpture of T1 horn dorsally: smooth. 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; smooth medially, longitudinally striate laterally. Shape of T6 in female: short, wider than long. Sculpture of S3: smooth.

Diagnosis.

This species is most similar to Calliscelio brachys in size and abbreviated notaulus. It may be distinguished from Calliscelio brachys in having A4 distinctly shorter than A3, A6 distinctly transverse in the female.

Etymology.

The specific epithet is to be treated as a noun in apposition, derived from the Latin for "be away," and refers to the abbreviated notaulus.
