Marbled hatchetfish look different in its various ranges. In the past, several subspecies were therefore described, such as C. fasciata from Brazil (Tabatinga), C. marowini and C. surinamensis from Suriname, and C. vesca from Guyana. Currently, however, these subspecies are not scientifically recognized. But they still exists as distinct morphospecies, so just keep the location names straight and don't mix different types.
