Diagnosis
Males of Paridris pallipes are similar to those of Paridris gongylos and may be easily separated by the simple occipital carina versus the crenulate occipital rim in Paridris gongylos. The dense microsculpture throughout the head and anterior mesosoma, absence of a transverse carina on T2 and smoothly convex posterior margin of T6 render the females of this species morphologically distinct among the specimens treated here.

Comments
Paridris pallipes exhibits remarkably little morphological variation for the large size of its geographical distribution. One specimen from Costa Rica, OSUC 265167, fits neatly into our concept of Paridris pallipes with the exception that it has a posteriorly directed spine on T1. Consequently, this specimen is determined only as Paridris until more specimens are available to assess if this is a morphological variation within Paridris pallipes, or if it should be treated as a separate species. The females of this species have macropterous and brachypterous forms. The lone specimen record of Paridris pallipes from Brazil (OSUC 323902) is worthy of mention because of its distance from any other specimen records, and may indicate that this species has been introduced to Brazil by humans.
