''Eigenmannia vicentespelaea'' is a species of weakly electric knifefish in the family Sternopygidae. Native to the São Domingos karst area in central Brazil, it is the only known South American knifefish to exclusively inhabit a subterranean habitat. Measuring up to long, ''E. vicentespelaea'' can be distinguished from its relatives by its translucent body and reduced or absent eyes. As some individuals retain well-developed eyes, this fish may have colonized caves only recently in evolutionary time. ==Taxonomy== Brazilian ichthyologist Mauro Luís Triques described ''E. vicentespelaea'' in a 1996 volume of the scientific journal ''Revue Française de Aquariologie'', from two specimens caught in 1978. He chose the specific epithet ''vicentespelaea'' from the São Vicente I cave, the type locality, and ''speleum'', Latin for "cave". Based on color pattern and morphology, it is included in the ''E. virescens'' species group with ''E. virescens'', ''E. trilineata'', and a third undescribed species.〔
