Oxudercidae

4.13 | Oxudercidae

Betancur-R et al. (2017) recognised Gobionellidae as a junior synonym for Oxudercidae . Here we follow Betancur-R et al. (2017) and update the family name for the species which were before placed in Gobionellidae as Oxudercidae .

Knipowitschia bergi , sometimes considered as Hyrcanogobius bergi , has not been found in the last decades and new field data is encouraged to test, if this species might actually be extirpated in the area.

The Rhinogobius species, considered invasive in the Caspian Sea basin, seems to be now widespread also in the Caspian part of the study area ( Japoshvili et al., 2020) and is expected to enter the Black Sea basin soon. There had been several studies aiming to identify this species, which was treated as R. cheni ( Vasil’eva & Kuga, 2008), R. similis ( Esmaeili et al., 2014) ,and R. lindbergi (Esmaeili, Sayyadzadeh, Eagderi, & Abbasi, 2018; Sadeghi, Esmaeili, Zarei, Esmaeili, & Abbasi, 2019). The name of this species in our list is provisional and needs further confirmation.
