Resumen

Olivella (Lamprodoma) volutella (Lamarck, 1811), a common shallow water species from Central America is, by first time, anatomically described based on dissections and drawings at camera lucida. Its most remarkable characters are the presence of a long posterior tentacle of the mantle with a pleated laminar expansion on its proximal end, stomach oval to rectangular with a wide muscle ribbon surrounding it and without internal cuticular coating, a gastric caecum plentiful of sediment, penis cylindrical laterally compressed and without a flagellum, and a strong asymmetry of the central nervous system with left cerebral ganglion substantially larger than the right one.
