Abstract

Sternaspis chilensis n. sp. is described based on specimens collected in channels and fjords of southern Chile and previously identified as Sternaspis scutata (Ranzani, 1817), originally described from the Meditarrean Sea. Sternaspis chilensis n. sp. is described based on the features of the shield with anterior margins rounded and anterior depression shallow; marginal shield chaetal fascicles arranged with an inverted C-shaped pattern; and distribution of the integument papillae. Sternaspis chilensis is widely distributed in the Magellan Province from Estero Reloncaví (41°32'54"S, 72°19'48"W) to Strait of Magellan (53°34'S, 70°04'W), between 50 and 515 m depth.

摘要

智利斯特纳虫新种（Sternaspis chilensis n. sp.）是根据在智利南部海峡和峡湾收集的标本描述的，这些标本先前被鉴定为斯氏斯特纳虫（Sternaspis scutata (Ranzani, 1817)），最初是从地中海描述的。智利斯特纳虫新种是根据盾板的特征描述的，其前缘圆形，前部凹陷浅；边缘盾板刚毛束呈倒C形排列；以及体表乳头的分布。智利斯特纳虫广泛分布于麦哲伦省，从雷隆卡维河口（南纬41°32′54″，西经72°19′48″）到麦哲伦海峡（南纬53°34′，西经70°04′），深度在50至515米之间。
