Diagnosis
Paridris saurotos is most similiar to Paridris convexa and Paridris isabelicae with which it shares elongate flagellomeres in males. The females may be quickly separated by the posteriorly directed spine on the horn of T1. Males of Paridris saurotos are best separated from Paridris isabelicae by the smooth sculpture of medial S2, which is longitudinally striate in the latter; and from Paridris convexa by the absence of microsculpture throughout the posterodorsal head.
Etymology
The Greek “saurotos”, meaning “spiked”, refers to the posteriorly projecting spine on the horn of T1 in this species. The epithet is treated as a noun in apposition.
