A new species of sleeper shark is described based on a 134.0 cm total length pregnant female collected from off Hualien, eastern Taiwan. The species belongs to a small species group (subgenus ) and can be distinguished from its congeners in having a smaller second dorsal fin, smaller eyes, more rows of teeth in the upper jaw and fewer in the lower jaw, and a different body proportion. Moreover, the specimen had 33 embryos, which is substantially more than the two other small species in the subgenus. Information on embryo biology are also provided.
基于从台湾东部花莲外海采集的一条全长134.0厘米的怀孕雌鲨，描述了一种新的睡鲨物种。该物种属于一个小型物种组（亚属），可通过以下特征与同属其他物种区分开来：第二背鳍较小、眼睛较小、上颌牙齿排数更多而下颌牙齿排数更少，以及身体比例不同。此外，该标本有33个胚胎，比该亚属的其他两个小型物种的胚胎数量多得多。还提供了胚胎生物学信息。
