Diagnosis
Among the species of the New World, Paridris soucouyant is most similar to Paridris gorn, with which it shares coarse punctation of the head and a characteristic shape of the metascutellum. The two are best separated by the presence of a longitudinal carina on the horn of T1 and rugulose sculpture of lateral T4–T5 in Paridris soucouyant. Etymology. This species is named for the soucouyant (pronounced sue-coo-yah) of Trinidadian folklore: a vampiric character that takes the form of a fireball and sucks the blood of its victims. The specific epithet is treated as a noun in apposition.
