Taxonomic Notes: There is evidence of a highly complicated taxonomy. Also that this widespread species may consist of Indian and Pacific ocean sister species.

Although Parenti and Randall (2000) list this as a single species extending from the Red Sea to the central Pacific, Kuiter (2002) reserves the name marginatus for the Red Sea population of this species and identified the Indian and Pacific Ocean populations as Halichoeres lamarii and further suggests that the Pacific ocean populations are Halichoeres annularis. Barber and Bellwood (2005) use molecular evidence to show that there are two clades in this species, Indian and Pacific Ocean but did not discuss the Red Sea populations. No formal taxonomic resolution has been published.
