Two new species of diphyllidean cestodes are described from the Persian Gulf, Echinobothrium persiense n. sp. from Rhinobatos punctifer Compagno & Randall and Echinobothrium hormozganiense n. sp. from Mustelus mosis Hemprich & Ehrenberg. E. persiense is the first record of a species of Echinobothrium van Beneden, 1849 from R. punctifer and these two new species increase the number of diphyllideans known from the Persian Gulf from one to three. The number of apical hooks of E. persiense (hook formula: {5-6 6/5 5-6}) is distinct from all other species in the genus except for E. affine Diesing, 1863, E. harfordi McVicar, 1976, E. bonasum Williams & Campbell, 1980, E. fautleyae Tyler & Caira, 1999, E. syrtense (Neifar, Tyler & Euzet, 2001) Tyler, 2006 (emend), E. chisholmae Jones & Beveridge, 2001, E. tetabuanense Ivanov & Caira, 2012, E. sematanense Ivanov & Caira, 2012 and E. weipaense Ivanov & Caira, 2012. Echinobothrium persiense can be distinguished from all other species of the genus with 11 apical hooks by a combination of the following features: armed cephalic peduncle, testes arranged in a single column, lateral hooklets arranged in two groups, U-shaped ovary, cephalic peduncle length (124-181 μm), genital pore and cirrus-sac position, and by having 10-14 spines per row on the cephalic peduncle. Echinobothrium hormozganiense has a hook formula of {12-15 16/15 12-15} and is similar to E. musteli Pintner, 1889, E. notoguidoi Ivanov, 1997 and E. diamanti Ivanov & Lipshitz, 2006 by possessing additional spines between the rostellum and the bothria. It differs from E. musteli by having an H-shaped ovary and lateral hooklets arranged in two lateral groups, and the number of spines per row on the cephalic peduncle (18-21) readily differentiates it from E. notoguidoi (24-26) and E. diamanti (95-118). With these two new species, Echinobothrium van Beneden, 1849 now includes 45 valid species.
