Gymnotocinclus anosteos

Description

Gymnotocinclus anosteos is a species of armored catfish (Loricariidae) endemic to Brazil, where it is found in the Tocantinzinho River in the Tocantins River basin. This species grows to a length of 4.4 centimetres (1.7 in) SL. The genus Gymnotocinclus is unusual among the Loricariidae due to its extremely reduced armor plates that are characteristic of the family, giving the fish a relatively naked body. This fish probably has a basal position in the subfamily Hypoptopomatinae.
