Inachus aguiarii
Described from specimens caught near the Sado estuary (Brito Capello, 1876). Arrábida was formerly the northernmost limit of its distribution (Nunes-Ruivo, 1961), but the species was recently found in Galicia, northern Spain, seemingly having expanded its range in the last decades (Cuesta et al, 2016).
