Taxonomy and systematics

edit

There were formerly 39 recognized species in this genus. However, the family Aphaniidae was split in 2020, and species were reallocated to eight monophyletic genera. Several species were reallocated; to five resurrected genera (Anatolichthys, Aphaniops, Kosswigichthys, Paraphanius, and Tellia) and two new genera Esmaeilius and Apricaphanius.[1]

Species

edit

Following the split, there are two valid species:[1]

Fossil record

edit

Fossils of extinct species, including A. crassicaudatus and A. yerevanicus, are known as far back as the Early Miocene of the Mediterranean and Caucasus regions.[3] are Fossils of Aphanius are found in strata of the Pleistocene of Italy (age range: from 11.608 to 5.332 million years ago.).[4]
