Dysommina orientalis Tighe, Ho & Hatooka, 2018: this volume (type locality: Dong-gang, southern Taiwan).

Remarks. The species has long been identified as Dysommina rugosa in Taiwan and Japan. Tighe et al. (2018) compared the morphological and genetic features and confirm that the specimens collected from Taiwan and Japan are different from the Atlantic population, and a new name is given.
