A new whipray, Himantura randalli sp. nov., described from material collected off Bahrain, Kuwait and Qatar, appears to be endemic to the Persian Gulf. It has been frequently confused with forms of the more widely distributed whipray Himantura gerrardi Gray and other presently unidentified species from the Indian Ocean. Himantura randalli sp. nov. is distinguished from these species by a combination of characters, i.e. disc shape, morphometrics, squamation (including its rapid denticle development and denticle band shape), plain dorsal disc coloration, and whitish saddles on a dark tail in young. It is a medium-sized whipray with a maximum confirmed size of 620 mm disc width (DW) and a birth size of around 150-170 mm DW. Males mature at approximately 400 mm DW. Himantura randalli sp. nov. is relatively abundant in the shallow, soft-sedimentary habitats of the Persian Gulf from where it is commonly taken as low-value or discarded bycatch of gillnet and trawl fisheries.
