Abstract
Charles Darwin obtained an important collection of fish species during his well-known voyage aboard the HMS Beagle around the world between 1832 and 1836. Despite his extensive tour of South America, his collection of fish in the La Plata basin was restricted to 4 localities and their surroundings: Buenos Aires (Río de la Plata), Rosario (Río Paraná), Montevideo and Maldonado. Until today the type locality of Corydoras paleatus (Jenyns, 1842) remains uncertain. While Darwin is known to have obtained this species in South America, upon arrival in England, the reference labels corresponding to the lot containing the specimens were lost (Jenyns, 1842). From that moment, the place where the type specimens were collected could never be established with certainty. The present work shows the results of an in-depth bibliographic review that, added to the analysis of detailed historical data and in situ surveys, it was possible to determine that lot No. 636, whose label was lost, corresponds to C. paleatus specimens, and the type locality of that species corresponds to Laguna del Potrero, Maldonado, Uruguay.

Resumen
Charles Darwin obtuvo una importante colección de especies de peces en su conocido viaje a bordo del HMS Beagle alrededor del mundo entre los años 1832 y 1836. Pese a su extenso recorrido por Sudamérica, su colecta de peces en la cuenca del Plata se restringió a 4 localidades y sus periferias: Buenos Aires (Río de la Plata), Rosario (Río Paraná), Montevideo y Maldonado. Hasta hoy la localidad tipo de Corydoras paleatus (Jenyns, 1842) era incierta. Si bien se sabe que Darwin obtuvo esta especie en Sudamérica, al llegar a Inglaterra, se extraviaron las etiquetas de referencia correspondientes al lote que contenían los especímenes (Jenyns, 1842). Desde ese momento, nunca se pudo establecer con certeza el lugar en el que fueron colectados los ejemplares tipo. En el presente trabajo se muestran los resultados de una profunda revisión bibliográfica que, sumado al análisis de datos históricos detallados y relevamientos in situ, se pudo determinar que el lote nº 636, cuya etiqueta se extravió, corresponde a los ejemplares de C. paleatus, y la localidad tipo de esa especie corresponde a la Laguna del Potrero, en Maldonado, Uruguay.
