Setation of upper frons: with sparse, short setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: granulate; smooth with sparse punctures. Sculpture of frons below median ocellus: largely smooth with sparse fine punctures. Sculpture of posterior vertex: densely punctate; granulate to rugulose. 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: smooth. Ocular setae: absent. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, distinctly longer than wide. Shape of female A6: as long as wide.

Color of mesosoma in female: orange throughout; black throughout; variably orange to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth throughout; largely smooth, granulate ventrally and posteriorly. Sculpture of netrion: smooth; rugose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: largely coriaceous with dense and fine punctures at poster end. 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 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 propo deum in male: rugose. Median keels on propodeum in female: absent. Mesopleural carina: absent. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth; largely smooth, rugose ventrally. Color of legs: pale yellow throughout; coxae pale yellow, otherwise orange to pale brown. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: nebulose, strongly pigmented. Setae on R: long, erect, surpassing the margin of the wing. Length of R: approximately as long as r-rs. Length of R1: greater than 3.0 × length of r-rs.

Color of metasoma in female: variably yellow to pale brown. Color of metasoma in male: brown throughout; reddish brown. Horn on T1 in female: large and distinct. Sculpture of T1 horn dorsally: transversely 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 posterior margin of T2; present on anterior margin of T2 medially, reaching posterior margin of T2 laterally. Sculpture of T3: smooth with longitudinal submedian striae. Shape of T6 in female: distinctly elongate, at least 2.0 × longer than wide. Sculpture of S3: densely punctate.

Diagnosis.

This species is most similar to Calliscelio laticinctus and Calliscelio longius in color, size and habitus. It may be distinguished from them by having A6 quadrate in female, whereas A6 is distinctly longer than wide in Calliscelio laticinctus and Calliscelio longius .

Etymology.

The epithet is used as a noun in apposition derived from the Latin word for shortness, in reference to the shortened A5 and A6.
