Other Phreatobius species
Phreatobius sanguijuela, Phreatobius dracunculus
Key differences: Distinguishing P. cisternarum from other Phreatobius species often requires detailed morphological examination, including fin ray counts, vertebral counts, and specific proportional measurements. For instance, P. sanguijuela has a more robust body and different fin ray counts. P. dracunculus is also depigmented and blind but has distinct morphological differences in fin structure and body proportions.
Other blind cave catfishes
Various genera (e.g., Rhamdia, Pimelodella, Trichomycterus)
Key differences: While other blind cave catfishes exist, Phreatobius cisternarum is unique in its family (Heptapteridae) and its extreme vermiform body shape. Many other blind catfishes, even if depigmented and blind, retain a more typical catfish body plan (e.g., larger head, more robust body, different fin configurations) compared to the highly elongated and slender Phreatobius.
