Two diatoms previously reported by H. KOBAYASI from the Ara-kawa ( Ara River ), Japan, were re-examined in detail using scanning electron microscopy. A new species, Navicula pseudacceptata, is proposed for the diatom that was identified as N. acceptata HUST. The generic position of the second, Stauroneis japonica H. KOB., is confirmed and a type is designated, thereby validating this previously invalid name.
