摘要

摘要报道了日本tellinia一新种Nitidotellina hachiensis。这个物种的外壳的特点是一对强壮的龙骨，从喙到后端，形成一个突出的后缺口。最近的个体只在濑户内海(冈山、广岛、山口和爱媛县)被发现，而迄今为止已知的一个化石记录来自于本州中部爱知县的千叶期(中更新世)丰桥组。活着的个体并不多见，主要生活在大海湾内部从退潮线到潮下带的沙泥底。由于最近的栖息地丧失和内湾环境的水污染，它可以被视为濒临灭绝。

Nitidotellina hachiensis n. sp. (Bivalvia: Tellinidae) from the Seto Inland Sea, between Honshū and Shikoku, western Japan

ABSTRACT A new species of tellinid, Nitidotellina hachiensis, is described from Japan. The shell of this species is characterised by a pair of strong keels that run from the beaks to the posterior end and forms a prominent posterior notch. The recent individuals are found only in the Seto Inland Sea (Okayama, Hiroshima, Yamaguchi and Ehime prefectures), while the one fossil record so far known is from the Chibanian (middle Pleistocene) Toyohashi Formation in Aichi Prefecture, central Honshū. Living individuals are uncommon and mainly found living in sandy mud bottoms from the low tide line down to the subtidal zone in the inner parts of large bays. It can be regarded as endangered due to the recent habitat loss and water pollution of inner bay environments.

期刊介绍： Molluscan Research is an international journal for the publication of authoritative papers and review articles on all aspects of molluscan research, including biology, systematics, morphology, physiology, ecology, conservation, biogeography, genetics, molecular biology and palaeontology. While the scope of the journal is worldwide, there is emphasis on studies relating to Australasia and the Indo-west Pacific, including East and South East Asia. The journal’s scope includes revisionary papers, monographs, reviews, theoretical papers and briefer communications. Monographic studies of up to 73 printed pages may also be considered. The journal has been published since 1957 (as the Journal of the Malacological Society of Australia until 1993). It is free to members of the Malacological Society of Australasia and the Society for the Study of Molluscan Diversity.
