Etymology: Pseudobunocephalus: The generic 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 genus have previously been mistaken for juveniles of other species.; lundbergi: The generic 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 genus have previously been mistaken for juveniles of other species.

Morphology | Morphometrics
Pseudobunocephalus lundbergi can be distinguished from all congeners by having the following unique characters within the genus: dorsal surface of skull ornamented with numerous bony knobs of equal size; distinct anterior and posterior cranial fontanels separated by a bony epiphyseal bar formed between the frontals; infraorbital canal exits from the sphenotic and extendsanteriorly past eye, bearing up to four pores; premaxilla without a posterolateral limb; and fifth centra with posteriorly directed processes that articulate with skeletal elements of the dorsal fin (Ref. 78999).
