A cytogenetic study of Diplomystes mesembrinus (Teleostei, Siluriformes, Diplomystidae) with a discussion of chromosome evolution in siluriforms
The mitotic chromosomes, nucleolus organizer regions (NORs), C-banding pattern and nuclear DNA content of Diplomystes mesembrinus were studied. The karyotype, with 2n=56 chromosomes (22m+24sm+6st+4a), has a high chromosome ...
Correction of the spelling of Trichomycterus eichhorniarum Miranda Ribeiro, 1912 (Siluriformes: Trichomycteridae)

Miranda Ribeiro (1912) described Trichomycterus eichorniarum based on specimens caught between the pseudo-rhizomes of the water hyacinth Eichhornia azurea and named the species referring to this circumstance. In the ...
Karyotype variability in eight species of the subfamilies Loricariinae and Ancistrinae (Teleostei, Siluriformes, Loricariidae)
Loricariidae is one of the largest fish families of the world, with about 650 species separated into six subfamilies. To date, cytogenetic data on only 56 species of this family are available. In the present study, the ...
The karyotype of Scoloplax distolothrix (Teleostei: Siluriformes: Scoloplacidae)
The karyotype of a fish species belonging to the family Scoloplacidae, Scoloplax distolothrix, is described for the first time. Cytogenetic studies showed that this species has 2n=50 chromosomes, 18 metacentrics, 18 ...
