| gyrodactylus neili n. sp. (monogenea: gyrodactylidae), a parasite of chain pickerel esox niger lesueur (esocidae) from freshwaters of new brunswick, canada. | gyrodactylus neili n. sp. (monogenea: gyrodactylidae) is described from the fins and body surface of esox niger lesueur (chain pickerel) (esocidae) from the st. croix river drainage, new brunswick, canada. g. neili n. sp. resembles most closely g. fryi cone & dechtiar, 1984, a parasite of e. masquinongy in north america, in having relatively large thin hamuli, well-developed marginal hook sickles with a relatively long, wide blade and short handle, a ventral bar with small antero-lateral process ... | 2006 | 16773231 |
| morphology and molecular taxonomy of gyrodactylus jennyae n. sp. (monogenea) from tadpoles of captive rana catesbeiana shaw (anura), with a review of the species of gyrodactylus nordmann, 1832 parasitising amphibians. | gyrodactylus jennyae n. sp. is described from the body surface and mouthparts of tadpoles of the bullfrog rana catesbeiana shaw imported presumably from missouri, usa, into a federal government facility in moncton, new brunswick, canada. its morphology resembles most closely that of g. chologastris mizelle, whittaker & mcdougal, 1969 described from two amblyopsids (blind cave fishes) in kentucky and north carolina. both species have long slender hamuli, a ventral bar with a relatively long membr ... | 2009 | 19472080 |
| a new genus and species of gyrodactylid (monogenea) from silver hake, merluccius bilinearis, in the bay of fundy, new brunswick, canada. | gyrocerviceanseris passamaquoddyensis n. gen., n. sp. is described from the gills of silver hake, merluccius bilinearis , in passamaquoddy bay, southwestern new brunswick, canada. diagnostic features include an oval haptor with asymmetrically distributed marginal hooks (3 pairs anterior, 5 pairs posterior) and a prominent muscular flange on the lateral margins, between the anterior and posterior groups of hooks. the hamuli are well developed, with a straight point, a short shaft, and an elongate ... | 2010 | 20738197 |
| taxonomy and host-specificity of gyrodactylus aideni n. sp. and g. pleuronecti (monogenea: gyrodactylidae) from pseudopleuronectes americanus (walbaum) in passamaquoddy bay, new brunswick, canada. | wild and cultured winter flounder pseudopleuronectes americanus (walbaum) from passamaquoddy bay were surveyed for species of gyrodactylus nordmann, 1832. two species were found: g. pleuronecti cone, 1981 and g. aideni n. sp, both members of malmberg's 'groenlandicus group'. although the hard parts in the haptor are very similar in the two species, hamuli of g. aideni are consistently shorter than those of g. pleuronecti. the two species differed by 35 base pairs in the its 1, 5.8 and its 2 regi ... | 2010 | 20960093 |
