Etymology. The species epithet is a noun in apposition based on the Portuguese common name of the tree on which the new species was collected, “Aroeira-Pimenteira.”

Remarks. Coelidiana aroeira sp. nov. resembles Coelidiana brasiliensis and Coelidiana diminuta due to the presence of a single ventral process on the aedeagus but the former differs in having the ventral process of the aedeagus basally fused to the shaft ( Fig. 1K View FIGURE 1 ).
