A new species of lanternshark, Etmopterus marshae (Squaliformes: Etmopteridae), is described from the Philippine Islands, western North Pacific Ocean. The new species occurs along insular slopes at a depth range of 322-337 m. The new species resembles other members of the "Etmopterus lucifer" clade in having linear rows of dermal denticles, and most closely resembles E. burgessi from Taiwan and E. evansi and E. pycnolepis from the South Pacific. It can be distinguished from all other members of the E. lucifer clade by a combination of characteristics, including length of anterior and posterior flank branches being of relatively equal length, straight vs. curved anterior flank marking, relative lengths of caudal markings, coloration, and relatively small size. A revised key to the revised key to the Etmopterus lucifer clade is provided.
一种新的灯笼鲨物种，马氏灯笼鲨（Etmopterus marshae，角鲨目：灯笼鲨科），在北太平洋西部的菲律宾群岛被发现并得以描述。该新物种出现在岛屿斜坡，深度范围为322 - 337米。这个新物种与“Etmopterus lucifer”分支的其他成员相似，具有成排的线状皮齿，并且与来自台湾的伯氏灯笼鲨（E. burgessi）以及来自南太平洋的埃氏灯笼鲨（E. evansi）和密鳞灯笼鲨（E. pycnolepis）最为相似。它可以通过一系列特征与“Etmopterus lucifer”分支的所有其他成员区分开来，这些特征包括体侧前后分支长度相对相等、体侧前部标记为直线型与曲线型、尾鳍标记的相对长度以及颜色，还有相对较小的体型。文中还提供了“Etmopterus lucifer”分支的修订检索表。
