Resumo

Species in the genus Bugula are globally distributed. They are most abundant in tropical and temperate shallow waters, but representatives are found in polar regions. Seven species occur in the Arctic and one in the Antarctic and species are represented in continental shelf or greater depths as well. The main characters used to define the genus include bird's head pedunculate avicularia, erect colonies, embryos brooded in globular ooecia and branches comprising two or more series of zooids. Skeletal morphology has been the primary source of taxonomic information for many calcified bryozoan groups, including the Buguloidea. Several morphological characters, however, have been suggested to be homoplastic at distinct taxonomic levels, in the light of molecular phylogenies. Our purpose was to investigate the phylogenetic interrelationships of the genus Bugula, based on molecular phylogenetics and morphology. A Bayesian molecular phylogeny was constructed using original and previously published sequences of the mitochondrial genes cytochrome c oxidase subunit 1 (COI) and the large ribosomal RNA subunit (16S). Morphological characteristics from scanning electron and light microscopy were used to confirm the clades detected by the molecular phylogeny. Our results suggest that the genus is composed of four clades, for which we provide diagnoses: Bugula sensu stricto (30 species), Bugulina (24 species), Crisularia (23 species) and the monotypic Virididentula gen. n. Ten species could not be assigned to any of those genera, so they remain as genus incertae sedis. Our findings highlight the importance of using molecular phylogenies in association with morphological characters in systematic revisions of bryozoan taxa. (AU)
