Mitochondrial DNA Part A, 2014
Ageneiosus pardalis is a trans-Andean member of the Neotropical freshwater fish family Auchenipteridae (Siluriformes). In this work, the complete mitochondrial genome of A. pardalis was pyrosequenced by FLX 454 technology. The mitochondrial genome is 16,484 bp in length and encodes 13 proteins, 22 tRNAs and 2 ribosomal RNAs.

Copeia, 1989
The Auchenipteridae is a neotropical freshwater catfish family composed of over 60 species in 21 genera. It is diagnosed as a monophyletic group on the basis of three synapomorphies: 1) a post-epioccipital process that reaches the nuchal plates or vertebral column: 2) a genital papilla formed with modified rays of the anal fin: and 3) a unique groove ...

Copeia, 2002
Abstract This study presents details of the ultrastructure of the spermatozeugmata and spermatozoa of the South American catfish, Trachelyopterus lucenai, an inseminating species. Spermatozoa are tightly packaged into unencapsulated bundles, spermatozeugmata, with as many as 130 cells comprising a single packet.

Parasitology Research
The construction of dams and hydroelectric plants affects biodiversity in aquatic environments and can facilitate the invasion of species. Few studies assess the long-term response of parasite fauna under these events. The aim of this study was to investigate possible changes in the endoparasite composition of the invasive catfish Trachelyopterus ...

The subfamily Centromochlinae (Siluriformes: Auchenipteridae) comprises Neotropical catfishes with the monophyly well-established based on both morphological and molecular evidence. However, their internal relationships, particularly between Tatia and Centromochlus, remain controversial, mainly due to the high morphological similarity among species of ...
