Etymology

Its specific name refers to the polymath Constantine Samuel Rafinesque (1783–1840).[7]

The name "doormat parkinglightfish" was coined by D. E. McAllister in his 1990 book A List of the Fishes of Canada, being one of many common names he conceived in the book (French: lampe-veilleuse pailasson).[8] These common names were subsequently used in the Encyclopedia of Canadian Fishes by Brian W. Coad.[9] In a review of Coad's book, Erling Holm remarked that many of the names coined by Mcallister differed significantly from the standard set by Robins et. al., deemed widely accepted, and promoted by the Committee on Names of Fishes.[10][11] For the names of deep-sea fish (including "doormat parkinglightfish"), which are unlikely to have day-to-day use, Holm deemed the names "unnecessarily complex, easily misspelled, or downright silly".[10]
