A total of 22 specimens of whiting Merlangius merlangus (L.) (Teleostei, Gadidae) from the northern Øresund, Denmark

were examined for Myxosporea. Zschokkella hildae Auerbach, 1910 (Myxidiidae), Gadimyxa sp. (Parvicapsulidae) and a species of

Bipteria occurred in the renal tubules of 9%, 18% and 68% whiting, respectively. Immature spores of the Bipteria species are very

occurred in the renal tubules of 9%, 18% and 68% whiting, respectively. Immature spores of the species are very

similar to spores of Myxoproteus formosus Kovaleva et Gaevskaya, 1979 originally described from the urinary system of whiting

from the Celtic Sea. We therefore consider Bipteria sp. from whiting in Denmark conspecifi c with M. formosus and propose Bipteria

formosa (Kovaleva et Gaevskaya, 1979) comb. n. The spore of Bipteria formosa is described in detail and compared with other

(Kovaleva et Gaevskaya, 1979) comb. n. The spore of is described in detail and compared with other

Bipteria spp. The phylogenetic position of B. formosa, based on partial 18S rDNA sequences, is closest to Leptotheca fugu Tun,

spp. The phylogenetic position of , based on partial 18S rDNA sequences, is closest to Tun,

Yokoyama, Ogawa et Wakabayashi, 2000 and the Sphaerosporidae.
