The absence of a chitinous nuchal scute; presence of an unpigmented, nonpapillated, and subcylindrical body in cross section; and weak anterior and posterior suckers all correspond to the description of Helobdella elongata . Specimens lacked eyespots, a characteristic noticed before for some individuals of this species from other localities (Klemm, 1982). Found on the underside of submerged rocks and accidentally attached to skin. Non-blood-feeding (liquidosomatophagous). Cox1 genetic
