On a new species of the shrimp genus Athanas Leach, 1814 (Crustacea, Decapoda, Alpheidae) from Iran

A new species of Athanas is described from the Iranian side of the Strait of Hormuz connecting the Persian Gulf with the Gulf of Oman. Athanas iranicus n. sp. is the only species in the genus characterised by the presence of dense setal brushes on the dorsolateral margin of the carpus and on most of the palm of the major and minor chelipeds; the presence of an additional setal brush on the dactylus of the major cheliped; a frontal margin with an untypically short rostrum and short, triangular extra-corneal teeth; and mostly concealed eyestalks.
