本文描述了日本东京湾东京峡谷斜坡上捕获的一条小妖精鲨（Mitsukurina owstoni Jordan，1898年）的一个雌性个体的体表标本。这个新物种很容易与其所有同类区分，因为雌性具有以下独特特征：（1）家系2的头胸侧叶和侧板没有边缘膜，（2）家系4的背板边缘光滑，（3）生殖复合体的后外侧叶向内侧弯曲，在中线上相互重叠，（4）第2和第3腿具有3节内足，以及（5）第4腿具有不完全的2节外足。
Echthrogaleus mitsukurinae sp. nov. (Copepoda, Siphonostomatoida, Pandaridae) is described based on a female recovered from the body surface of the goblin shark, Mitsukurina owstoni Jordan, 1898, captured on the slope of the Tokyo Canyon at about 400 m depth in Tokyo Bay, Japan. This new species is easily distinguishable from all its congeners in having the following unique features in the female: (1) the lateral lobes of the cephalothorax and the lateral plates of pediger 2 are devoid of marginal membranes, (2) the dorsal plates of pediger 4 have a smooth margin, (3) the posterolateral lobes of the genital complex are widely curved medially and overlap each other across the midline, (4) legs 2 and 3 have 3-segmented endopods, and (5) leg 4 has an incompletely 2-segmented exopod.
