Lepotrema justinei is a species of lepocreadiid digenean parasitic in the intestine of marine fish.

[1] This species was not characterised by molecular means but was distinguished from other species of the genus Lepotrema by morphological characteristics.

[1] According to Bray, Cutmore & Cribb, the species was named justinei "after Professor Jean-Lou Justine of the Muséum National d’Histoire Naturelle, Paris, France, in recognition of his massive contributions to marine fish parasitology".

[1] The masked triggerfish, Sufflamen fraenatum, (Tetraodontiformes: Balistidae) is the type-host of Lepotrema justinei.

The type-locality is the Interior Lagoon near Récif Toombo, off Nouméa, New Caledonia.
