Family Synaphobranchidae

Ho et al. (2015c) listed 7 genera and 17 species from Taiwan. In the present study, two of these are described as new, and the presence of Synaphobranchus affinis in Taiwan has become doubtful because of a lack of voucher specimens. Here we add two more new species of Dysomma, bringing the total species of the family to 21 or 22 (the latter including S. affinis). There are still unidentified or undescribed species awaiting further investigation.
