The genus Leptochiton Gray, 1847 is a paraphyletic group of small, pale, and usually deepwater chitons. They lack some of the morphological shell characters that are important in the systematics of Polyplacophora, and species identification within this genus is challenging. One species complex in the North Pacific includes at least 11 species that were historically synonymized or confused with Leptochiton rugatus (Carpenter in Pilsbry, 1892). Scrutiny of ecological and biogeographical patterns has helped to separate species lineages within this clade and support morphological diagnoses. Based on morphological and molecular studies, a new species is described that was previously confused with both Leptochiton assimilis (Thiele, 1909) and Leptochiton rugatus. This new species is widely distributed in the summer-warmed bays of the southern Primorye, Moneron Island, Northern Japan, Kunashir, and the Yellow Sea. This species is at least ~8% different in the COI barcode region from Leptochiton rugatus s.s. Morphological differences between the new species and closely related species are presented.

Leptochiton subrugatus sp。十一月 (软体动物:Polyplacophora)来自北太平洋低北水域

Leptochiton Grey属,1847 年是一个并系群,由小型、苍白且通常在深水的石斑鱼组成。它们缺乏一些在 Polyplacophora 系统学中很重要的形态外壳特征,并且该属内的物种鉴定具有挑战性。北太平洋的一个物种群包括至少 11 个在历史上与Leptochiton rugatus同义或混淆的物种(Carpenter in Pilsbry,1892)。对生态和生物地理模式的审查有助于分离该进化枝内的物种谱系并支持形态学诊断。根据形态学和分子研究,描述了一个新物种,该物种以前与Leptochiton assimilis (Thiele, 1909) 和细鳞甲藻。这一新种广泛分布于滨海南部、莫奈龙岛、日本北部、国后和黄海夏季温暖的海湾。该物种与Leptochiton rugatus ss的 COI 条形码区域至少有约 8% 的不同。新物种和密切相关物种之间的形态差异被呈现出来。
