Biospeedotrema jolliveti is a species of trematodes inhabiting hydrothermal vent fishes (particularly Ventichthys biospeedoi) 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 can be differentiated by vitelline fields which extend slightly into its post-testicular region; its intestinal bifurcation is dorsal to its ventral sucker; its genital pore is somewhat submedian or median; its cirrus sac is short and the caeca are large and overlap the testes.{{cite journal|last1=Bray|first1=R.
