Pterolebias is a genus of killifish from the family Rivulidae which are native to temporary swamps and ponds in South America. It includes two groups, which sometimes are regarded as separate genera: Pterolebias ( sensu stricto) from the southern Amazon and Paraguay (including the Pantanal) river basins, and Gnatholebias from the Orinoco (including the Llanos) river basin. [2]
Depending on the exact species, these annual killifish reach up to 7–12 cm (2.8–4.7 in) in total length. [3]
There are four recognized species in Pterolebias according to FishBase, [3] but two of these are sometimes placed in a separate genus, Gnatholebias. The two groups are relatively distantly related and if kept in a single genus Pterolebias is paraphyletic. [2] [4]
