Description: Pseudobunocephalus is distinguished from all other aspredinid genera by the following unique features: mandibular teeth restricted to a patch near symphysis of lower jaw; no contact between the metapterygoid and quadrate; autopalatine posteriorly forked with two separate cartilages; absence of the fourth pharyngobranchial; absence of gill rakers on all branchial arches; and lack of bifid hemal spines on vertebrae that articulate with anal-fin pterygiophores. As defined Pseudobunocephalus contain a new species, P. lundbergi from the Orinoco River basin, along with five other species previously assigned to the genus Bunocephalus: P. amazonicus, P. bifidus, P. iheringii, P. quadriradiatus, and P. rugosus. Aquarium Care: Very small species that can probably be kept as per other members of this family with a quite tank with sand and plants. Diet: Tablet foods and small live foods. Etymology: The genus name is a combination of the Greek word pseudes, meaning false or deceptive, plus the aspredinid genus Bunocephalus. It alludes to the fact that members of this new genus have previously been mistaken for juveniles of various species of Bunocephalus. The specific name of iheringii: In honour of German-Brazilian zoologist Hermann von Ihering (1850-1930), who helped collect type. Remarks: A new species is described from streams of the lower Tocantins and the Mearim river drainages, in North and Northeast of Brazil, Pseudobunocephalus timbira Leão, Carvalho, Reis & Wosiacki, 2019.
