Diagnosis.

Paridris isabelicae is similar to Paridris convexa and Paridris saurotos . Females of Paridris saurotos have a posteriorly projecting spine on the horn of T1, and those of Paridris convexa have a small transverse carina at the base of the horn. The horn of T1 is smooth in Paridris isabelicae . Males of Paridris isabelicae may be separated from the males of both other species by the presence of longitudinal striation on S2 medially.

Etymology.

This species is named for Cafetal La Isabelica, a coffee plantation where the holotype was collected. The epithet is treated as a noun in the genitive case.
