An eastern Atlantic and Mediterranean species of which a single, small specimen was recorded from Portland Bay (present day Islas Canning), western Patagonia by Miers (1881, as Alpheus sp.) and identified by Coutière (1899) as A. dentipes; possibly mislabelled (see Holthuis 1952) or potentially a mis-identification of the more northern, extra-limital Alpheus inca Wicksten & Méndez, 1981.
