ABSTRACT.—Guyana, located in northern South America north of Brazil between Venezuela and Suriname, includes portions of the Orinoco, Amazon, and Courantyne river basins, a majority of the Essequibo River Basin, and all of the Berbice and Demerara river basins. Partly as a consequence of historical and contemporary drainage complexity, Guyana has a remarkably diverse freshwater fish fauna. Here, we compile the first comprehensive list of Guyana’s freshwater fishes, totaling some 657 species-level taxa (97 first records, 117 endemics and at least three introduced species), based on photographic records, published reports, and over 145,000 type and non-type specimens in 29 museum collections. The IUCN conservation status for each species isprovided. We separately list an additional 151 undocumented species that are possibly or likely present in Guyana based on their adjacent distributions in either the Orinoco River Delta in Venezuela or the Courantyne River in Suriname. The largest holdings of fish specimen vouchers and frozen fish tissues from Guyana are housed at the Royal Ontario Museum, Toronto (ROM), Auburn University Museum, Auburn (AUM), University of Michigan Museum of Zoology, Ann Arbor (UMMZ), and the Academy of
Natural Sciences of Drexel University, Philadelphia (ANSP). Additional important collections of Guyanese fishes are deposited at the Centre for Study of Biological Diversity, Georgetown, Guyana (CSBD), Field Museum of Natural History, Chicago (FMNH), Illinois Natural History Survey, Champaign (INHS), The Natural History Museum, London (NHMUK, formerly BMNH), Oregon State University, Corvallis (OS), and the US National Museum, Washington (USNM). Despite the many collections that have been made in Guyana, many species still lack vouchered specimens or tissues, and many more species require formal description.
Notes: Donald Taphorn is the senior author of the paper. There are an additional 18 authors listed. My apologies to all of them for not listing every name.
A total of 218 species of catfishes are covered in the paper (this might be with a minor plus or minus if I goofed up on my counting).
