Other Farlowella species
Farlowella spp.
Key differences: Distinguishing F. acus from other Farlowella species often requires close examination of rostrum length and shape, body proportions, and subtle differences in fin ray counts or dermal ossification patterns. For example, F. vittata generally has a shorter, broader rostrum, and F. gracilis might have slightly different body markings. Expert taxonomic knowledge is often needed for definitive identification within the genus.

Sturisoma spp.
Key differences: While also elongated Loricariids, Sturisoma species typically have a broader head, a less pronounced rostrum, and often possess a more flattened body profile. Their caudal fin filaments are also generally much longer and more prominent than in Farlowella.
