The occurrence of the parasitic marine leech Stibarobdella moorei (Hirudinea: Piscicolidae) along the northwest Mexican Pacific coast is described for the first time. This ectoparasite was collected from the skin of the Octopus bimaculatus (Molusca: Octopodidae). Stibarobdella loricata is synonymized with S. moorei, this species resembles other species of the genus based on tubercle patterns and the presence of papillae and a marginal fringe on the oral sucker. This is the first record of S. moorei in Mexico and of its parasitic association with the host O. bimaculatus. The present finding throws new light on the biodiversity and host preference of the ectoparasite and suggests a successful migration to unusual host. The coast of the Pacific Ocean, particularly in the Bay of Los Angeles, Baja California, Mexico is a new geographical distribution area for S. moorei, and O. bimaculatus is a new host reported for this leech. The morphology of this ectoparasite is briefly described.
