| Abstract |
The author, after discovering in 1980 in the New Caledonia lagoon an unknown white colored Mitridae, very similar to the Scobricola casta (Gmelin, 1791), but also to Scabricola newcombii (Pease, 1869), proceeds to a synthesis of the last founds of S.newcombii in the Pacific Ocean. Numerous species are commonly found In other places than Hawaii Islands where S. newcombii was described to be endemic. This work is also based on the fact that albino species of S. newcombii exist. This is not consistent with the original description which described it with a black to brown band covering the last whorl of the shell. This black band is part of the animal and does not disappear even after being washed with bleach. That is not the case concerning S. casta that becomes all white after washing. It is quite difficult to discriminate between an albino S. newcombii and a S. casta without its black markings. So the author makes a new definition of distribution areas of S. newcombii and describes its albino sub species Scabricola newcombii irisae n ssp. |
