Valid as Pseudomugil majusculus Ivantsoff & Allen 1984.
Papua New Guinea; brackish.
"Morphologically, P. majusculus and P. signifer are very close. The premaxillaries in
both species are indistinguishable, and both have a parhypural bone (the only osteological
attributes examined). The fin rays and spines in the only known specimen are damaged and
their morphology is difficult to determine. However, in P. majusculus, the gill rakers are
longer and more numerous (14) than in P. signifer (12)."
Known only from a mangrove swamp off Cape Ward Hunt, north-eastern Papua New
Guinea. [A second specimen has been collected off Ferguson I., D'Entrecasteaux Group,
at the time this paper was going to press"
