Biospeedotrema biospeedoi is a species of trematodes inhabiting hydrothermal vent fishes (particularly Thermichthys hollisi) in the south eastern Pacific Ocean. It can be distinguished from its family by its symmetrical testicular configuration; its uterus passing between the testes. Furthermore, it differs from its cogenerates by the shape of its body; its uterine extent is posterior to its testes and its small vitellarium.
