Abstract

Five species of brachyuran Crustacea from the Middle Miocene are described from the Guri Member of the Mishan Formation in southwestern Iran. The species include the leucosioids Leucosia persica; Seulosia sp. cf. S. rhomboidalis; Myra sp.; the portunoid Portunus withersi and the xanthid Demania ahramensis n. sp. The paleobiogeographic affinities of these genera reinforce previous interpretations of a wide distribution between the Persian Gulf and the Indopacific regions.

Keywords: Crustacea, Decapoda, Brachyura, Miocene, southwestern Iran.
