"Acantholochus unisagittatus" is a species of parasitic copepod belonging to the family Bomolochidae. It is a parasite on the gills of common snook and has only been recorded in coastal waters off Rio de Janeiro State. In one study over half of the host fish sampled in this area carried this parasite.

The female is up to 1.4 mm in length and can be distinguished from congeners by the presence of only one seta (as opposed to two) on the inner surface of the second and third endopod. The male is as yet unknown.
