Nueva localidad para Parampheres bimaculatus (Opiliones: Gonyleptidae): probable registro histórico de la especie en Argentina.

In this note, the first record in Argentina of the harvestman Parampheres bimaculatus, a species from the Pampas of Brazil and Uruguay, is presented. The nearest known records come from north Uruguay, 180 km away in a straight line from Salto Grande. Some brief commentaries about the faunistic differences between both sides of the Uruguay River and the environmental changes of the collecting site are included. If the label data are correct, this is the first record of the species from Argentina, although the possibility of a labeling error is discussed. [ABSTRACT FROM AUTHOR]
