    Members of the onchoproteocephalidean genus Phoreiobothrium Linton, 1889 infect carcharhinid and sphyrnid sharks. Although the Persian Gulf harbors a rich fauna of sharks, the taxonomic diversity of Phoreiobothrium in this region has been explored little. A new species of Phoreiobothrium is herein described from Carcharhinus sorrah (Müller et Henle) off southern Iran. Cestodes were isolated from the spiral intestine of Carcharhinus sorrah, fixed in 10% seawater-buffered formalin, and stored in 70% ethanol. For morphological examinations, worms were stained using acetic carmine; a subset was prepared for SEM. Phoreiobothrium sorrahcola n. sp. is the first record of the genus from C. sorrah and most closely resembles Phoreiobothrium rozatii Alijanpour Darvishi et Haseli, 2019 recently described from the Gulf of Oman. However, it differs from P. rozatii in its possession of the rectangular, rather than triangular, bothridia, a longer cephalic peduncle (878-1300 vs 466-841), the longer axial prongs of lateral and medial hooks (B 56-80 vs 43-52; B' 66-98 vs 46-62), and a greater maximum width of worm at level of scolex (302-415 vs 215-298). With the description of this new species, three species of Phoreiobothrium have been reported so far from the southern waters of Iran. Phoreiobothrium now includes 17 valid species infecting 16 shark species.
