samples, including the type series of both the new species in this reference.
Eponymy: Din-Moo Chen is described in the etymology as an excellent fisherman who collected (off northeast Taiwan) most samples for the authors’ studies, including the type series of both new species in the publication which included the eponymous species [...] (Ref. 128868), visit book page.
