FusiloricariaFowler, 1940 Loricaria is a genus of armored catfish native to South America.

Its external morphology shows few shared derived characters, making comparison with other genera difficult.

Loricaria has been hypothesized to occupy a basal position among members of the subtribe Loricariina, with the other genera possessing derived characters.

Based on the characteristics of its mouth, Loricaria appears to maintain a close relationship with representatives of the Pseudohemiodon group.

[1] Sexual dimorphism includes hypertrophied development of the pectoral fin spines, blunt odontodes on the pelvic and anal fin spines, and tooth crowns becoming shortened and rounded in mature males.
