Gymnotus coatesi La Monte, 1935

Gymnotus coatesi La Monte, 1935: 1 , fig. 1. Type locality: Amazon River , Brazil. Holotype: AMNH 12624; 180 mm TL.

Rhamphichthys cingulatus Brind, 1935: 5 , unnumbered fig. Type locality: one of the side streams which connect with the main stream of the Amazon River on its southern bank, about three hundred miles from Para at the mouth of the river. Syntypes (2): private collection of author, possibly not saved; about 8 inches TL. Brind mentions additional specimens at the New York Aquarium and a pet shop, but it is not clear whether he actually viewed them or was just relaying information of their presence from other sources.

Remarks: Redescribed in Crampton, Albert (2004). Synonymy follows Campos-da-Paz (2000b), with a note suggesting that the holotype of Gymnotus coatesi may have been one of the specimens observed by Brind. LaMonte’s paper was published on 18 February, 1935, while the footer in Brind’s paper indicates that it was part of the issue for February, 1935, but no more precise date of issue was found in the copy at AMNH (D. Shih, pers. commun.). Unless a more precise date is established for Brind’s paper that is prior to 18 February, it must be treated as having been published on the last day of February, thereby giving priority to Gymnotus coatesi .

Distribution: Lower Amazon River basin, Pará, Brazil ( Campos-da-Paz, 2000b).
