Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

Females of this species are most similar to Calliscelio longius and Calliscelio prolixus in color, size and habitus. It can be separated from Calliscelio longius by A4 is slightly longer than A3 and A5 shorter than A3, from Calliscelio prolixus by the presence of T1 horn and the elongate T6. Males of Calliscelio laticinctus are similar to Calliscelio flavicauda and Calliscelio longius . It may be separated from Calliscelio flavicauda by T3 with submedian longitudinal striae and the brown hind femora, from Calliscelio longius by A11 is approximately 3.0 × longer than wide.
