【摘要】 2018—2022年作者在渤海湾大型底栖动物调查中采集到多个微小型腹足类标本,经分类学研究发现它们为入江拟新螺(Pseudonoba yendoi Yokoyama, 1927),该种之前未在中国报道,为中国新记录种。本文中对其贝壳、厣的形态进行了拍照和测量,并利用扫描电子显微镜对其齿舌进行了观察。此外,对该种在渤海的分布情况和生态习性进行了讨论。入江拟新螺属于耐污种,主要分布于泥砂质底质环境中,在中国渤海湾近岸海域分布密度较高。入江拟新螺在中国的发现不仅提升了海洋生物多样性认知,同时也表明中国对海洋底栖生物特别是微小型生物的调查和研究仍需进一步加强。更多还原

【Abstract】 During a macrobenthic survey at Bohai Bay from 2018 to 2022, several microgastropod specimens were collected. Morphological observations of the specimens suggest that they belong to Pseudonoba yendoi(Yokoyama, 1927). This collection is a new record of this species in Chinese waters. In this study, the shells and opercula were photographed and measured, and the radula was examined using scanning electron microscopy. Additionally, the distribution and ecological habits of this species in the Bohai Sea are discussed. This marine snail belongs to a pollution-tolerant species and is mainly distributed in muddy-sandy sediments, with a high density of distribution in the coastal waters of the Bohai Sea. The discovery of this species in China enhances our understanding of marine biodiversity and underscores the need for further investigation and research on marine benthic organisms, particularly those of micro-and small-sized species.更多还原
