. A new species of myxosporean of the genus Kudoa was found in the muscle tissues of Pamatoschistus minutus (Pallas, 1770), a migratory fish species from the Mediterranean Sea. Previously this Kudoa species had been observed in Pomatoschistus microps (Krøyer, 1838), a sedentary species of the Vaccarés lagoon system. the parasite caused rapid myoliquefaction of the affected muscles within one hour after host death. Using both light and electron microscopy, whitish, longitudinal, spindle‐shaped bodies, 2‐5 mm long and 1‐2 mm wide, were found in the caudal peduncle or in muscle tissues of the abdominal wall. Spore length, width, and thickness (n = 30) ranged between 4.4‐6.0 üm, 6.4‐8.0 üm, and 4.4‐6.0 üm, respectively, while the polar capsules averaged 2.5 times 1.5 üm (n = 30). Anatomic comparison with other myxosporean parasites enabled us to determine this to be a new species that we name Kudoa camarguensis n. sp.
