Apistoloricaria is a genus of armored catfishes native to South America.

Apistoloricaria is not well diagnosed and upon further examination, may prove to be a synonym of Rhadinoloricaria.

[2] In members of this genus and other closely related genera, the body is strongly depressed and the pelvic fins are used for locomotion, enabling these fish to appear to "walk" on the substrate.

[1] Sexual dimorphism is apparent through differentiated lip structure.

[1] These species are abdomino-lip brooders; eggs are laid in a single layered mass, and are attached to the surface of the lower lip and abdomen of the male.
