Enhydrictis is a genus of extinctmustelid, belonging to the subfamilyGalictinae. The type species, and best known, isEnhydrictis galictoides from thePleistocene ofSardinia andCorsica. Some authors attribute species from mainland Eurasia to the genus, but this is disputed, with others considering the genus endemic to Sardinia-Corsica.

Taxonomy

[edit]

The exact number of species ofEnhydrictis has been a matter of debate.^[2] One species ofPannonictis,Pannonictis pilgrimi, has been classified as a belonging toEnhydrictis (asEnhydrictis ardea), although this is unlikely.^[3]^[4] A 2019 study also suggests that the genusOriensictis ofAsia should be considered a synonym ofEnhydrictis as well.^[5] In 2016, a new species fromAlgeria was described. Known asEnhydrictis hoffstetteri, it is the first member of the genus known fromAfrica.^[6] Other scholars have considered the attribution of this species toEnhydrictis doubtful, and that the species should be placed inPannonictis instead.^[7]^[8] In 2018 a new species,Enhydrictis praegalictoides, was described from Middle Pleistocene aged sites on Sardinia; it is likely ancestral toE. galictoides. The Corsica-Sardinian species ofEnhydrictis are thought to have evolved from aPannonictis-like ancestor.^[7]

Enhydrictis and its relatives are classified as belonging to the subfamilyGalictinae^[8] and the tribe Galictini. While Galictini was widespread in Eurasia during thePliocene andEarly Pleistocene, the only extant members of the tribe, the grisons (Galictis) and the Patagonian weasel (Lyncodon), are endemic to Central and South America.^[7]

Description

[edit]

Enhydrictis galictoides was a fairly large, robust terrestrial mustelid.^[9] When first described, it was considered to be an otter-like species adapted to an aquatic lifestyle, but studies on the limb bones do not support such claims.^[10]

Paleoecology

[edit]

Before the arrival of humans on the islands in about 8000 BC, during the Middle and Late Pleistocene, Corsica and Sardinia had their own highlyendemic depauperate terrestrial mammal fauna which included a species of dwarfmammoth (Mammuthus lamarmorai), the Tyrrhenian vole (Microtus henseli), the Sardinian pika (Prolagus sardus), the Tyrrhenian field rat (Rhagamys orthodon) one or two species of shrew belonging to the genusAsoriculus, amole (Talpa tyrrhenica), theSardinian dhole (Cynotherium sardous), three species ofotter (Algarolutra majori,Sardolutra ichnusae,Megalenhydris barbaricina) and adeer (Praemegaceros cazioti). All of these species are now extinct.^[11]
