Abstract:
Phylogenetic relationships among the trichomycterid catfishes are investigated for the first time using
molecular sequence data. Data derived from mitochondrial and nuclear DNA sequences for representatives
of 17 genera were analyzed to test previous hypotheses of relationships among trichomycterid subfamilies,
the monophyly of the subfamily Stegophilinae, and the monophyly and relationships among the
genera of parasitic members of the family. We analyzed 2325 aligned base-pairs from mitochondrial 12S,
16S, ND4 (tRNAHis tRNASer), and the nuclear histone H3 gene for representatives of 10 of 12 stegophiline
and 3 of 4 vandelliine genera, plus 10 outgroup taxa selected to represent the range of subfamilial diversity.
Maximum parsimony and likelihood approaches resolved a monophyletic semiparasitic Stegophilinae
as the sister-group of the obligate hematophagous Vandelliinae. At the level of subfamilies, the
pattern of relationships of the parasitic members among the remainder of the family is fully congruent
with the most recent hypothesis of relationships for trichomycterids based exclusively on morphological
data. Within stegophilines, our results differ from multiple previous morphological studies in recovery of
(1) Haemomaster and Ochmacanthus as sister-taxa, (2) the morphologically plesiomorphic Pareidon
microps nested within a relatively distal part of the tree topology, (3) Apomatoceros as sister to Henonemus,
rather than to the morphologically similar Megalocentor. These result indicate that parasitism arose
once and was unreversed within the Trichomycteridae. Survey of diet and feeding morphology among
trichomycterids suggests that the semiparasitic lifestyle of the members of the Stegophilinae was
retained in the enigmatic Pareiodon microps, despite reversal to the generalized trichomycterid condition
of the associated morphological specializations found in all other stegophilines. These results further support
the reconstruction of semiparasitism, rather than blood feeding, for the shared common ancestor of
the parasitic Trichomycteridae.
