A murieid, dredged by the French-Indonesian "CORINDON" expedition (1980) in the Strait of Makassar was recently brought to my attention. After carefully checking in the literatures, it appears to be new, but one problem was remaining unresolved: its classification in an appropriate genus. The most important points or indicators for a subfamilial or generic placement for Muricidae are: the general outline of the shell, the operculum and radular characteristics. The shell of Nipponotrophon makassarensis shows some affinities with the ocinebrine subgenus Ocinebrellus Jousseaume 1880 (Type sp. by O.D. Murex eurypteron Reeve 1845). General form, length, winged varices Unfortunately, the open canal, the typical muricine operculum and' the radula lead me to consider this genus and subfamily as not valid for the new species. The shell shows also some affinities with the genus Pterynotus Swainson 1833 (Type sp. by S.D.: Murex pinnatus Swainson 1822). However, the Pterynotus species bears always 3 varices (except for some species, questionably put in that genus, a.o. Pt. martinetana (Roding 1798) but those have a typical dentate aperture and no winged varices), which leads us once more far away from the new species. Another possible genus might be the trophonine Trophon Montfort, 1810 (Type sp. by O.D.: Trophon magellanicus Gmelin 1791). This seemed to be the best location for our species but the operculum and the winged varices are not typical for Trophon, species.
