Globocephaloides wallabiae Johnston et Mawson, 1939, is resurrected as a valid species and is redescribed. G. wallabiae is distinguished from its closest congener, G. macropodis Yorke et Maplestone, 1926, by the spicules (length and tip) and pattern of the bursal rays. G. wallabiae occurs commonly in Macropus dorsalis (Gray, 1837) in north-eastern Queensland, but is also present in Petrogale mareeba Eldridge et Close, 1992 and P. assimilis Ramsay, 1877. By contrast, G. macropodis is found commonly in M. agilis (Gould, 1842) and P. persephone Maynes, 1982 in the Northern Territory and north-eastern Queensland, and occurs incidentally in other hosts, probably as a result of host-switching ((Aepyprymnus rufescens (Gray, 1837), P. brachyotis (Gould, 1841), P. inornata Gould, 1842, M. dorsalis, M. parryi Bennett, 1835, M. giganteus Shaw, 1790 and Largochestes conspicillatus Gould, 1842)). This morphological study, with additional host and geographical distributional data, provides support for the resurrection of the species.

Pseudogilquinia pillersi (Southwell, 1929), a poorly known species of trypanorhynch, is redescribed from plerocerci collected from Epinephelus coioides (Hamilton, 1922), Epinephelus malabaricus (Bloch et Schneider, 1801) (Serranidae) and Plectropomus laevis (Lacépède, 1801) (Serranidae) off New Caledonia. These were compared with specimens from Lethrinus atkinsoni Seale, 1910 and Lethrinus miniatus (Forster, 1801) (Lethrinidae) off the north-east coast of Australia as well as syntypes from Protonibea diacantha (Lacépède, 1802) from Sri Lanka. Although size differences were found in parts of the scolex as well as in the sizes of the tentacular hooks, the hook arrangements were identical in all specimens. The differences observed were attributed provisionally to intra-specific variation across a wide geographic and host range.
