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: interrupted. Length of OOL: less than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: granulate. Ocular setae: absent. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, as long as wide. Shape of female A6: distinctly wider than long. Form of male antennal flagellomeres: filiform, A11 approximately 2.0 × longer than wide. Length of A5 tyloid in male: greater than 0.5 × length of A5.

Color of mesosoma in female: yellow throughout; yellow with mesoscutellum pale brown. Color of mesosoma in male: yellow throughout; variably yellow to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth anteriorly, granulate posteriorly. Sculpture of netrion: smooth. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: granulate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: absent. Sculpture of mesoscutellum: granulate. Shape of metascutellum: posterior margin rounded, approximately 3.0 × wider than long. Sculpture of metascutellum in female: smooth. Sculpture of metascutellum in male: rugose. Dorsal propodeum in female: not excavate medially, lateral propodeal carinae meeting anteromedially. Sculpture of dorsal propodeum in female: smooth to rugulose. Sculpture of dorsal propodeum in male: rugulose. Median keels on propodeum in female: absent. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth dorsally, densely punctate ventrally. Color of legs: pale yellow throughout; hind coxa pale brown, otherwise pale yellow. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline with infuscate band in the middle. 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: yellow with variable pale brown patches; yellow throughout. Color of metasoma in male: variably yellow 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 T2 in female: reaching posterior margin of T2. 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 suni in color, size and habitus, and it is also similar to small specimens of Calliscelio sfina . It can be separated by the presence of an infuscate band in the middle of the fore wing.

Etymology.

The epithet is used as a noun in apposition derived from the Latin word for smallness, in reference to the body size.
