Lophocephalus Benham, 1937 Mauicetus is a genus of extinct baleen whale from the Late Oligocene of New Zealand.

Mauicetus was originally named Lophocephalus by William Benham, but that name was already used for a beetle, and Benham provided the replacement name Mauicetus.

[1][2] Three more species were named in 1956: M. brevicollis, M. lophocephalus, and M.

[3] Nowadays, Mauicetus parki is considered a stem-balaenopteroid, while M. lophocephalus and M. waitakiensis have been reclassified in Eomysticetidae, with M. lophocephalus and M. waitakiensis being assigned to Tokarahia and Tohoraata.
