Identification The genus Potamoglanis is a group of miniaturized Trichomycterinae, diagnosed by the following traits: angle of 35–40° between the main longitudinal axis of the head and the main axis of the autopalatine; thin tubular shape of the second ceratobranchial; presence of six or seven anal-fin rays; eyes dorsally placed on head; opercular and interopercular odontodes patches not juxtaposed; absence of a distal process on the hyomandibula; and presence of a long process on the anterior region of the hyomandibula.
