Calliobothrium spp. (Eucestoda: Tetraphyllidea: Onchobothriidae) in Mustelus schmitti (Chondrichthyes: Carcharhiniformes) from Argentina and Uruguay
Three species of Calliobothrium inhabit the spiral intestine of Mustelus schmitti in Argentina and Uruguay. Calliobothrium verticillatum australis is redescribed and its taxonomic status modified to species as C. australis. Calliobothrium barbarae n. sp. can be distinguished from all other species o...

| description |
Three species of Calliobothrium inhabit the spiral intestine of Mustelus schmitti in Argentina and Uruguay. Calliobothrium verticillatum australis is redescribed and its taxonomic status modified to species as C. australis. Calliobothrium barbarae n. sp. can be distinguished from all other species of Calliobothrium, which are small bodied, nonlaciniate, and without accessory piece between the bases of axial hook, by worm length, number of segments, cocoon morphology, and hooks shape. Calliobothrium lunae n. sp. is different from other Calliobothrium spp., which are small bodied, nonlaciniate, and have an accessory piece, by the number of segments and testes, hook shape, cocoon morphology, and the presence of ciliumlike projections on the distal surface of muscular pads. Calliobothrium australis is clearly distinguished from other large-bodied, laciniate species of the genus by worm length, number of testes, ovary shape, cocoon morphology, hook shape, and in being hyperapolytic. The oioxenous specificity involving Calliobothrium spp. and Mustelus spp. described by previous authors is confirmed in this study. |
