摘　　要：重新研究Kobayashi(1968)报道的来自泰国的Nippononaia carinata,以及Delvene和Munt(2011)报道的来自西班牙的Subnippononaia fordi标本;建立新亚属Nippononaia(Thainippononaia)Stiller and Chen,以及新种Nippononaia(Thainippononaia)hispaniensis Stiller and Chen,并认为新亚属代表Nippononaia属内的最早演化阶段,填补了Nippononaiidae科演化史的一个空白,即Eonippononaia阶段与Nippononaia(Arctonaia)阶段之间的空白。A new subgenus, Thainippononaia Stiller and Chen （type species： Nippononaia carinata Kobayashi, 1968） of the Cretaceous non-marine bivalve genus Nippononaia is erected. It differs from the other congeneric subgenera especially in its submedian V-ribs forming larger angles （VA） of 38°-45°. The new subgenus is known from Early Cretaceous strata of Thailand and Spain. Some specimens from Spain are assigned to the new taxon Nippononaia （Thainippononaia） hispaniensis Stiller and Chen subgen, nov. sp. nov. The subgenera of the genus Nippononaia are briefly discussed. Nippononaia （Thainippononaia） is regarded as the earliest subgenus of Nippononaia, and it may represent an evolutionary stage intermediate between the Eonippononaia stage and the Nippononaia （Arctonaia） stage.
