Remarks.

This species was originally described by Yamaguti (1968) as Haliotrema annulocirrus and transferred to the genus Euryhaliotrematoides , as E. annulocirrus , by Plaisance and Kritsky (2004). Recently, Kritsky (2012) proposed the synonymy of Euryhaliotrematoides with Euryhaliotrema . As result, this species was transferred as Euryhaliotrema annulocirrus . Haliotrema annulocirrus Yamaguti 1968, Euryhaliotrematoides annulocirrus ( Yamaguti 1968) Plaisance and Kritsky 2004, Parahaliotrema affinis Mizelle and Kritsky 1969, Haliotrema affinis ( Mizelle and Kritsky 1969) Vala et al. 1982 and Haliotrema angulocirrus Yamaguti 1968 are considered synonyms of this species. Euryhaliotrema annulocirrus is distinguished from all other species of the genus by having an enlarged slit-like vaginal pore with serrated posterior lip and a conspicuous, elongate and heavy coiled tube of the MCO.
