🐟 Physical Description

Gymnotocinclus is distinguished from all other hypoptopomatine genera by the following uniquely derived features: extreme reduction of body dermal plates; absence of the lateral connecting bone; absence of bifid hemal spines on the abdominal vertebrae posterior to the first anal-fin proximal radial; and odontode tips on last dermal plates on the caudal peduncle dorsally or anteriorly curved. Gymnotocinclus is also distinguished by a number of non-exclusive traits: maxillary barbel adnateto the lower lip; lateral ethmoid almost completely encapsulating the nasal organ; ventral margin of preopercle straight, not deflected medially; pectoral girdle exposed and supporting odontodes only in a restricted lateral area near base of pectoral fin; and absence of a pectoral-fin slit .: elongated.
