Diagnosis.

Paridris gorn is most similar to P. soucouyant, particularly in the bispinose shape of the metascutellum and punctate-rugose sculpture of the head. These two species may be separated by the sculpture of T4-T5: punctate-rugose in Paridris soucouyant , smooth in Paridris gorn . Additionally, females of Paridris gorn have a horn on T1 that is either smooth or has shallow punctures along its longitudinal midline. In Paridris soucouyant a carina is present along the dorsal crest of the horn.

Etymology.

This species is named after a reptilian alien race from the original Star Trek television series for the similar appearance of their compound eyes. The epithet is treated as a noun in apposition.
