| Descriptions and illustrations are given of four species of mailed catfishes belonging to the subfamily Loricariinae, tribe Harttiini. Two species are assigned to Lamontichthys P. de Miranda Ribeiro, 1939: Lamontichthys filamentosus (La Monte, 1935) (type-species, of which Harttia filamentissima C. H. Eigenmann & Allen, 1942, is provisionally considered a junior synonym), based on a total of thirteen specimens, including all type-specimens, from Brazil, Bolivia, Peru, and Ecuador (all from tributaries of the Rio Amazonas system), and Lamontichthys stibaros n. sp., based on two specimens from Ecuador, sympatric with the former species. Harttia microps C. H. Eigenmann & Allen, 1942, is redescribed from three out of the five type-specimens,... |

| Three new species belonging to two different genera of South American mailed catfishes of the subfamily Loricariinae are described and figured. A discussion of and comparative notes on related species are added. Rineloricaria formosa n. sp. is described from the Río Inírida/Río Orinoco drainage in Colombia, from the Río Atabapo (Río Orinoco drainage) in Venezuela, and from the Rio Tiquié and Rio Uaupés (Rio Amazonas drainage) in Brazil. It is compared with Rineloricaria morrowi Fowler, 1940, with Rineloricaria melini (Schindler, 1959), and with Rineloricaria fallax (Steindachner, 1915). The lectotype of the latter species is herein designated, and a discussion on the misidentification of R. fallax with Loricariichthys brunneus (Hancock, 1828) is added.... |

| Hemiodontichthys acipenserinus (Kner, 1854) is redescribed and figured after examination of 132 specimens from the Rio Amazonas, Essequibo River, and Rio Paraguai systems, including five syntypes, from which the lectotype is selected. Reganella depressa (Kner, 1854) is redescribed and figured after examination of 7 specimens from the Rio Amazonas system, including two syntypes, from which the lectotype is selected. Relationships of the monotypic genera Hemiodontichthys Bleeker, 1862, and Reganella Eigenmann, 1905 with other genera are briefly discussed. |

| A large number of previously unrecorded specimens of mailed catfishes of the genus Metaloricaria Isbrücker, 1975 (Loricariinae, tribe Harttiini, subtribe Metaloricariina) is compared with the known specimens from French Guiana and Surinam. This results in the recognition of two subspecies, viz., M. paucidens paucidens Isbrücker, 1975, from the rivers Oyapock and Maroni (French Guiana, Surinam), and M. p. nijsseni (Boeseman, 1976) from the rivers Suriname, Saramacca, Nickerie and Corantijn (Surinam). These subspecies were originally described as two different species, even within two different genera: Metaloricaria paucidens Isbrücker, 1975, and Harttia nijsseni Boeseman, 1976. Morphometric and meristic data, together with illustrations are given of the two... |

| The taxonomy of the common guppy, Poecilia reticulata Peters, 1859, is reviewed and the closely related Campoma guppy, P. wingei n. sp., is described. Formerly, the common guppy was not judged to be closely related to any other species of Poecilia, but the new species is the second species to be allocated in the subgenus Acanthophacelus Eigenmann, 1907. The recognition of P. wingei results from observed character displacement, i.e., on the interaction between two closely related species in a shared environment. In addition to differences in coloration, behaviour also indicates specific differences. The area in which P. wingei occurs, the Campoma region at the base of the Paría Peninsula in Venezuela, hints to an origin of the subgenus Acanthophacelus prior... |

| This publication presents a catalogue of the taxa of the neotropical family Loricariidae, the mailed catfishes, including about 600 described species and 70 genera. An attempt is made to assign each species to its proper genus and to arrange the genera into an approximate phylogenetic order. Numerous new combina tions have become necessary. A new tribe, consisting of two new subtribes, and three new genera are herein established. Notes on type-material, recorded in the literature subsequent to an original description, are added. Literature references aim to include all publications containing original descriptions and proposals of new names. |

| Two species of South American Mailed Catfishes of the genus Pseudoloricaria Bleeker, 1862 are redescribed and figured from type-specimens and additional material: Pseudoloricaria laeviuscula (Valenciennes, 1840), and Pseudoloricaria punctata (Regan, 1904). Since the provenance of the holotype of P. laeviuscula is unknown, the type-locality of this species is restricted to the mouth of the Rio Tapajós at Santarém. The lectotype is selected from the three syntypes of P. punctata, and its type-locality is restricted to the Rio Amazonas at Manaus. P. laeviuscula is distributed only in the Rio Amazonas basin in Brazil, whereas P. punctata occurs in several river systems, viz. the Rio Amazonas basin in Brazil, Peru, and Ecuador, in the Rio Parnaiba, Est. Piaui,... |

| A redescription and figures of Corydoras nattereri Steindachner, 1877, are given together with a description and figures of a new species, Corydoras prionotos, sympatric with Corydoras nattereri, with comparable dimensions and a similar colour pattern. A total of 1066 specimens were examined, including primary type-material of Corydoras juquiaae Von Ihering, 1907, and of Corydoras nattereri triseriatus Von Ihering, 1911, which are both placed in synonymy of C. nattereri, the holotype of which is lost. A neotype for Corydoras nattereri is designated. Corydoras prionotos differs from C. nattereri mainly in having the medial border of the pectoral-fin spine strongly serrate. |

| The South American genus of mailed catfishes Loricaria Linnaeus, 1758 is reviewed. Almost all primary type-material and additional specimens are examined. Descriptions, tabulated morphometric and meristic data, and illustrations are presented of eleven species: Loricaria cataphracta Linnaeus, 1758 (syn.: Plecostomus flagellaris Gronovius, ed.
