Length of A5 tyloid in male: approximately 0.3 × length of A5.

Color of mesosoma in female: orange throughout; yellow throughout. Color of mesosoma in male: orange throughout; yellow throughout. Sculpture of dorsal pronotal area: rugose; smooth. Sculpture of lateral pronotal area: smooth throughout. Sculpture of netrion: smooth. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: smooth with sparse punctures; coriaceous. Shape of mesoscutellum: semiellipsoidal. Scutoscutellar sulcus medially: weakly foveolate. Sculpture of mesoscutellum: smooth with sparse fine punctures; coriaceous. Shape of metascutellum: broad, short. Sculpture of metascutellum in female: smooth; rugose. Sculpture of metascutellum in male: rugose; smooth. Dorsal propodeum in female: shallowly excavate medially, with lateral propodeal carinae widely separated. Sculpture of lateral propodeal area in female: rugose.

Mesopleural carina: absent. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth; largely smooth, rugose ventrally. Color of legs: orange throughout; pale yellow throughout. 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: orange throughout; yellow throughout. Color of metasoma in male: orange throughout; variably orange to pale brown. Horn on T1 in female: large and distinct; present as a small bulge. Sculpture of T1 horn dorsally: smooth; rugulose; transversely striate; smooth to somewhat 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: present on anterior margin of T2 medially, reach posterior margin of T2 laterally. Sculpture of T3: smooth with longitudinal submedian striae; longitudinally striate throughout. Shape of T6 in female: short, subtriangular. Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

This species is most similar to Calliscelio amadoi in color and size but it can be easily distinguished by having A5 and A6 in female distinctly longer than wide, whereas in Calliscelio amadoi A5 is slightly longer than wide, A6 quadrate.

Etymology.

The epithet is used as a noun in apposition derived from the Greek word for mixture, in reference to the variations in female antennae color and T1 horn sculpture.

Comments.

This species is well supported by many characters, although there are variations in female antennae color and T1 horn sculpture. The common color of the female antennal club is dark brown to black, while there are a few exceptions that A7, A8 brown, A9-A12 white to pale yellow. T1 horn usually is smooth, while a few species rugulose, or transversely striate, or smooth to somewhat transversely striate. These variations are gradual among specimens. Therefore we consider them as intraspecific rather than interspecific.
