Diagnosis
Paridris aenea is most similar to Paridris lemete (endemic to Puerto Rico). The females of these species are easily separated by the number of basiconic sensilla on A8: one in Paridris aenea, and two in Paridris lemete; and a carina is present along the crest of the horn of T1 in Paridris lemete but not in Paridris aenea. The males of Paridris aenea may be separated by the coarse rugose or areolate sculpture of the mesopleuron ventral to the femoral depression; in Paridris lemete the ventral mesopleuron is mostly smooth with sparse punctation.

Comments
The large geographical distribution of Paridris aenea is accompanied by morphological variation, some of which is correlated with particular regions. Specimens from Cuba and Jamaica have smaller eyes (and consequently a larger OOL) and a pronounced transverse carina on T2 that protrudes laterally, making the anterior width of T2 distinctly greater than the posterior width of T1. Typically, the genal striae do not extend above the midpoint of the eye and are concentrated in the posterior half of the gena. Specimens from Tobago, and some from mainland South America, have elongate genal striae that extend to the vertex, or even around the eye, becoming dorsally continuous with the malar striae. Finally, three female specimens, OSUC 181316, 181345, 334201, have a minute horn on T1. They are otherwise consistent with our concept of Paridris aenea, and we consider them to be variants within this species.
