Morphologic and molecular redescription of Catostylus mosaicus conservativus (Scyphozoa: Rhizostomeae: Catostylidae) from south-east Australia

Catostylus mosaicus (Quoy & Gaimard, 1824) is a rhizostome jellyfish endemic to eastern Australia. Originally described from Port Jackson (Sydney) in New South Wales (Quoy & Gaimard, 1824), the species is thought to range from Port Phillip (Melbourne) in Victoria to the Torres Strait (Kramp, 1965; Southcott, 1982), i.e. across three biogeographic boundaries. Given recent reports of multiple cry...

Chromosomal complements of some Atlantic Blennioidei and Gobioidei species (Perciformes)

A remarkable degree of chromosomal conservatism (2n=48, FN=48) has been identified in several families of Perciformes. However, some families exhibit greater karyotypic diversity, although there is still scant information on the Atlantic species. In addition to a review of karyotypic data available for representatives of the suborders Blennioidei and Gobioidei, we have performed chromosomal ana...

Redescription of Proteocephalus bagri and p. Rhamdiae (Cestoda: Proteocephalidae), parasites of Rhamdia quelen (Siluriformes: Pimelodidae) from South America, with comments on morphological variation.

The pimelodid fish Rhamdia quelen (Quoy et Gaimard, 1824) in South America harbours two species of proteocephalid cestodes, Proteocephalus bagri Holcman-Spector et Mañé-Garzón, 1988 and P. rhamdiae Holcman-Spector et Mañé-Garzón, 1988. These species are redescribed based on a detailed morphological study, supported by multivariate analysis (principal component analysis). Features distinguishing...
