Spatuloricaria is a genus of armored catfishes native to South America and Panama.

Its dentition, with few teeth on the premaxillae, and its abdominal cover consisting of minute disjointed platelets resembles that of some representatives of the Loricaria group.

Conversely, the papillose surface of the lips and sexually dimorphic features are more characteristic of the Rineloricaria group.

[1] This genus is distributed in the northwestern part of the South American subcontinent, in drainages of the Pacific and Atlantic Slopes of the Andes.

[1] Sexual dimorphism includes hypertrophied development of claw-like odontodes along the sides of the head and on the pectoral spines in mature males.
