Abstract Background The families Xanthdiae and Pilumnidae are two common families of the brachyuran crabs in the Persian Gulf. These families are represented with 25 and 23 species, respectively, in the Gulf. Methods Brachyuran crabs from Abu-Musa Island, Iran, Persian Gulf have been collected and examined for a biodiversity project conducted during 2014 and 2015. The material was mostly collected from the intertidal and shallow subtidal using hand and snorkeling. Results In total, 16 Xanthidae species were identified, of which four are new records for the Persian Gulf and includeAtergatis integerrimus (Lamarck, 1801), Zosimus aenus (Linnaeus, 1758), Zozymodes cavipes (Dana, 1852), Macromedaeus crassimanus (A. Milne-Edwards, 1867). One further new record for the Persian Gulf is the pilumnidCryptopilumnus pereiodontus (Davie and Ghani, 1993). Conclusion The present five new records increase recognised species of the families Xanthidae and Pilumnidae of the Persian Gulf to 29 and 24, respectively.
