AbstractA new species of the coccidian genus Aggregata Frenzel, 1885 (Apicomplexa, Aggregatidae) is described from the digestive tract of Todarodes sagittatus (Lamarck), an ommastrephid squid that lives in temperate waters in the northeastern Atlantic Ocean. Using light microscopy, oöcysts were 225–333 m in length and 220–323 m in width. Each oöcyst contained 600–1,000 sporocysts. Sporocysts were 16–18 m in length and 15–17 m in width, with a smooth surface and thick wall. Each sporocyst contained 4–8 sporozoites each with a length of 11– 13 m. This paper presents the description of a new Aggregata species in a nerito-oceanic flying squid. Moreover, it extends the distribution of Aggregata to oceanic cephalopod host species. A. sagittata represents the third named species in the genus Aggregata in European waters and the seventh worldwide.
