Etymology: Icelinus: From Icelus = the Morpheus name; mythology; pietschi: Named for Theodore W. Pietsch, University of Washington, Seattle, principal investigator for the International Kuril Island Project, 1994-1999, during which the species was discovered (Ref. 45337).
Eponymy: Dr Theodore ‘Ted’ Wells Pietsch III (d: 1945) was a professor of ichthyology at the University of Washington, Seattle (1978 onwards) and is an American systematist and evolutionary biologist especially known for his studies of anglerfishes. [...] (Ref. 128868), visit book page.
