Revision of the species of Pisidium C. Pfeiffer, 1821 from Argentina, Bolivia, Chile, Peru and Uruguay (Bivalvia, Sphaeriidae). The present knowledge on the systematics and geographic distribution of species of the genus Pisidium C. Pfeiffer, 1821 in southern South America is scattered in many English written short papers. The present is an updated and comprehensive Spanish-written revision of the known species of southern South American pisidiids, aiming to be a valuable tool to those interested in studies on the ecology of freshwater environments. All nominal species of Pisidium from Argentina, Bolivia, Chile, Peru and Uruguay described since 1835, after d’ Orbigny´s Voyage (1826-1833), are here critically reviewed. Each of the 19 Pisidium species recognised as valid is briefly described through an enlarged diagnosis and fully illustrated by scanning electron microscope photographs. Some poorly known species (e. g.: Pisidium dorbignyi, Pisidium lebruni and Pisidium magellanicum) are fully redescribed and figured.
