Remarks.

This species was described for the first time by Yamaguti (1968) as Pseudohaliotrematoides aurigae . In 2004, Plaisance et al. recorded this species from 10 species of Chaetodon and one species of Heniochus ( Chaetodontidae), and transferred it to the genus Haliotrema as H. aurigae . Haliotrema aurigae presents a tubular MCO bent near base base; base trapezoid; filamentous accessory piece, elongated, serving as a guide for the distal portion of the MCO. Dorsal anchor base/shaft junction hinged, with elongate superficial root and short, deep root. Ventral anchor with short roots and broad, slightly fenestrated base. Dorsal bar straight, bone-shaped. Ventral bar rod-shaped, an inverted broad U. New geographical record for Palmyra Atoll.
