Etymology: Pylorobranchus: From the Greek pylorus (gatekeeper) and branchos (gill), neuter, in reference to the lappet-like structure located before the gill opening; hoi: Named for Hsuan-Ching Ho, who has studied the eels and many other fishes of Taiwan.
Eponymy: Dr Hsuan-Ching Ho (d: 1978) is a Taiwanese ichthyologist who is Associate Professor at the Institute of Marine Biology at the National Dong Hwa University, Taiwan (2014–present). [...] (Ref. 128868), visit book page.
