Stropocheilus miersi Da Costa, 1904 is recharacterized by the conchology and morphology of the soft parts, the latter for the first time. Palial complex, reproductive and digestive systems provide important characteristics to enrich the knowledge of the genus Strophocheilus Spix, 1827. The presence of four arched folds in the posterior region of the pediose mass and the morphology of the suprapediose gland offered more data to identify and diagnose the species.
