The Efferia can be distinguished from related genera such as Triorla by features of the male and abdominal coloration patterns. Males of many Efferia species possess a distinctly swollen genital capsule, while females lack this structure. Accurate determination to species typically requires reference to original species descriptions and comparison with .
