Etymology: Gymnotus: Greek, gymnos = naked (Ref. 45335); omarorum: Named for Omar Macadar and Omar Trujillo-Cenoz, pioneers in the anatomical and physiological study of electrogenesis in Gymnotus.
Eponymy: The two people after whom this species is named are Omar Macadar and Omar Trujillo-Cenoz, both of whom are Uruguayan scientists and pioneers in the study of the anatomy and physiology of electrogenesis in knifefishes and who have worked closely [...] (Ref. 128868), visit book page.
