Here we present a discovery of a new fish from the family Gobiidae in Lake Prespa, which is known as a European hotspot for biodiversity and endemism. This is the first detection of a fish species from this family, not only regarding this lake but also in the territory of the Republic of North Macedonia in general. The close examination of the recorded specimens revealed the presence of perianal organ surrounding the anus. This unique organ and various other observed morphometric and phenotypic characteristics point out to the genus Economidichthys. |
