Resumo: The taxonomic status and anatomy of Leiosolenus (Labis) patagonicus (d'Orbigny, 1846 in 1834-1847) has been revised. This boring bivalve, belonging to the family Mytilidae, is the only Lithophaginae species distributed along the Argentinean coast. None of the fossil species mentioned for this area must be considered as a synonym of d'Orbigny´s species. Leiosolenus patagonicus is characterized by a thin shell, longitudinally elongated, with subterminal umbos and commarginal striae. The calcareous depositions on the outer surface of the shell are extended beyond the posterior margin. This species has well developed purple siphons, well differentiated morphologically from each other. Incurrent siphon is wider than excurrent, opened at the ventral edge and provided with a basal siphon valve at the base. Two pairs of demibranchs type B (1) from Atkins were observed. The shell characters and internal morphology were compared with other related species of the genus living along the South American coast. Finally, repository, type locality and habitat conditions were informed.
