Abstract

A new species of lanternshark, Etmopterus samadiae (Squaliformes: Etmopteridae), is described from off northern Papua New Guinea, in the western Central Pacific Ocean. The new species resembles other members of the "Etmopterus lucifer" clade in having linear rows of dermal denticles and most closely resembles E. brachyurus from the western North Pacific. The new species occurs along insular slopes between 340 and 785 m depth. The new species can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including length of anterior flank branch markings being slightly shorter than its posterior branch, a longer caudal base marking, and irregular and variable number of black, horizontal, dash-like marks on sides of body. Molecular analysis based on the NADH2 marker further supports the distinction of E. samadiae from other members of the E. lucifer clade.

摘要

一种新的灯笼鲨——萨马迪亚灯笼鲨（Etmopterus samadiae）（角鲨目：灯笼鲨科），在西太平洋中部的巴布亚新几内亚北部海域被发现并被描述。这种新物种与“Etmopterus lucifer”分支的其他成员相似，具有成排的皮齿，并且与北太平洋西部的短尾灯笼鲨（E. brachyurus）最为相似。新物种出现在深度为340至785米的岛屿斜坡上。新物种可以通过一系列特征与“Etmopterus lucifer”分支的其他成员区分开来，包括体侧前部斑纹分支长度略短于后部、尾基部斑纹较长，以及身体两侧黑色水平短线状斑纹不规则且数量多变。基于NADH2标记的分子分析进一步支持了萨马迪亚灯笼鲨与“Etmopterus lucifer”分支其他成员的区分。
