Proterorhinus semipellucidus is a species of gobiid fish, a tubenose goby originally described from the Gharasu River near Gorgan Bay of the Caspian Sea in Iran. Following the systematic decomposition of the tubenose gobies it was suggested to be a more widespread and invasive taxon distributed in the fresh waters of the Caspian Sea basin.Neilson M.E., Stepien C.A. (2009) Evolution and phylogeography of the tubenose goby genus Proterorhinus (Gobiidae: Teleostei): evidence for new cryptic species. Biological Journal of the Linnean Society, 96(3): 664–684. It may be the same species as that known as Proterorhinus nasalis.Brian W. Coad Freshwater Fishes of Iran (accessed 22 Feb 2015)
