Etymology: Notolychnus: Greek, noton = back + Greek, lychnos, -ou = torch (Ref. 45335).
Eponymy: Both these species are named after the research vessel ‘Valdivia’ and the Valdivia expedition (1898–1899), Germany’s first expedition to explore deep seas. The holotypes were collected during the expedition. (Ref. 128868), visit book page.
