要約

Three small new species of the genus Thalassiosira Cl. (T. yunnaniana Khursevich & Kocioiek, T. bradburyi Khwsevieh & Kocioiek and T. iraidae Khursevich & Kocioiek) studied in light and scanning electron microscope are described from the Miocene freshwater deposits in Yunnan Province, China. All studied species have internal flat cribra covering individual loculate areolae on the valve surface. Moreover, an expanded diagnosis of T. kilarskii Kaczmarska known from the Miocene diatomites of western USA is also presented. Unlike the Chinese species, T. kilarskii has areolae with internal radial zigzag paths of continuous cribra. Also, the presence of valve face faltoportulae is reported in this species, a characteristic described as lacking in the original description.
