+ Apterichtus moseri (Jordan & Snyder, 1901)

Sphagebranchus moseri Jordan & Snyder, 1901:864, fig. 14 (type locality: Suruga Bay, off Namazu, Japan, depth 63 fathoms [115 m]) .

Apterichtus moseri (Jordan & Snyder, 1901): McCosker & Hibino, 2015:70. Ho et al., 2018a: this volume.

Remarks. A specimen was collected from southwestern Taiwan. The species was previously recorded from only two localities, Japan (type locality) and the Marquesas Islands, but the latter is probably based on misidentification.
