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. Entomology: 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 new genus have previously been mistaken for
juveniles of various species of Bunocephalus.
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
South America:Upper Amazon River basin of Peru.
Type locality:Peru: Samiria,
Chinguito [= Cocha Shinguita or Shirguita].
