Abstract:
A hypothesis on the phylogenetic relationships of the neotropical catfish family Cetopsidae is proposed on the basis
of the parsimony analysis of 127 morphological characters and most of the species currently recognized. The family
and its two recognized subfamilies, the Cetopsinae and Helogeninae, are corroborated as monophyletic, in agreement
with recent studies. Previously proposed classifications of the Cetopsinae, however, were found to be poorly representative
of the phylogenetic relationships within the subfamily. Major generic rearrangements are implemented in
order that the classification of the Cetopsinae reflects the phylogenetic hypothesis.
Pseudocetopsis
Bleeker (1862)
was found to be polyphyletic and to include several disjunct lineages. One of these lineages, recently named as the
genus
Cetopsidium
Vari, Ferraris, and de Pinna (2005), is the sister group to the rest of the Cetopsinae.
Denticetopsis
Ferraris (1996) is the next sister group to the remainder of the Cetopsinae. The remaining species of the Cetopsinae
belong to one of two sister genera,
Paracetopsis
Bleeker (1862) and
Cetopsis
Spix and Agassiz (1829). The latter genus
includes species formerly assigned to
Hemicetopsis
Bleeker (1862),
Bathycetopsis
Lundberg and Rapp Py-Daniel
(1994) and
Pseudocetopsis
Bleeker (1862). Continued recognition of
Hemicetopsis
and
Bathycetopsis
would have
required the creation of several additional new genera for various species previously in
Pseudocetopsis
that form a
series of sister groups to a clade composed of
Cetopsis oliveirai
(Lundberg and Rapp Py-Daniel, 1994),
C. coecutiens
(Lichtenstein, 1819) and
C. candiru
(Spix and Agassiz, 1829).
Cetopsis oliveirai
is a highly paedomorphic species that
displays surprising similarities with conditions in juvenile specimens of
C. coecutiens
, a species that attains a large
body size. Such similarities are not evident in adult specimens of the latter species. A new classification is proposed,
within which the subfamily Cetopsinae consists of three tribes, the Cetopsidiini, the Cetopsini and the Denticetopsini.
The results of the study form the basis for a discussion of the phylogenetic position of the family within the Siluriformes,
the phylogenetic biogeography of the Cetopsidae, paedomorphosis and gigantism in the family, and the
effect of different semaphoronts on the intrafamilial phylogeny.
