| Abstract: | Kronborgia isopodicola sp. n. (Turbellaria: Neorhabdocoela: Fecampiidae) is described from the South Island of New Zealand. The species has a parasitic phase within the haemocoel of the intertidal isopod Exosphaeroma obtusum (Dana). Sexes are separate: each female worm, emerging when mature from its host, secretes a cocoon around itself in which it is joined by a male. Cocoons are found under rocks, are approximately 10 mm long and reflect the shape of the contained female. The worms spawn and lay numerous egg capsules, each containing two embryos. Although placed in Kronborgia Christensen and Kanneworff, 1964 because it is dioecious, K. isopodicola exhibits some characters typical of the genus Fecampia Giard, 1886. It differs from all other described fecampiids by its possession of eyes throughout life. |
