Etymology: Ogilbia: Taken from Ogilby, 1887-1915, icthiologist and zoologist (Ref. 45335); robertsoni: Named for Dr. D. Ross Robertson, Smithsonian Tropical Research Institute, Panama (STRI).
Eponymy: James Douglas Ogilby (1853–1925) was an Irish-born Australian ichthyologist and taxonomist, son of the famous zoologist William Ogilby (below). [...] Dr David Ross Robertson (d: 1946) is an ichthyologist whose bachelor’s degree (1966) and doctorate (1974) were awarded by The University of Queensland, Australia.
