We report some brachyuran crabs from the late Miocene of Dar Pahn unit, Makran Province, Iran. The studied specimens have been assigned to Ixoides MacGilchrist, 1905, with I. miocenicus n. sp. (Leucosiidae Samouelle, 1819) and Persianus arcuatus n. gen., n. sp. (Portunidae Rafinesque, 1815). Ixoides miocenicus n. sp. represents the first fossil representative of the genus, enlarging its stratigraphic range to the Miocene. Persianus arcuatus n. gen., n. sp. represents the first report of a portunid crab from the Miocene of Iran. We also report an indeterminate majoid crab, representing the first report for the Majoidea from the Miocene of Iran. Finally, one portunid crab is compared with Persianus n. gen. based on some similar morphological characters.
