Parotocinclus jequi

Parotocinclus jequi has an elongated body and it reaches a standard length of 5.4 cm (2.1 in). It has a single spine and 7 soft rays in its dorsal fin and 6 in its anal fin. This catfish has no plates on the abdomen between the pectoral girdle and the anus.

Parotocinclus jequi is known from just three localations, all in the Jequitinhonha River basin, including the type locality at the headwaters of the Jequitinhonha River, the Marapuamba stream in Turmalina and in the Vacaria River. This species is a small, herbivorous catfish which was originally collected from a headwater stream at 1,200 m (3,900 ft) a. s. l.. The fishes were collected from a shallow section, with a depth between 0.3 and 1.20 m (1 ft 0 in and 3 ft 11 in), where the water was clear and the streambase made up of gravel and stones.
