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.
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
foods. |
