| Abstract | |
The present study is a taxonomic survey of polychaetes from of the family Sabellidae collected from intertidal zone, along the coast off the State of São Paulo, and deep waters, off the states of Rio de Janeiro and São Paulo. The material came from the projects \"Biodiversity of Intertidal Polychaetes (Annelida: Polychaeta) on Rocky Shores off the State of São Paulo, Brazil\", BIOTA/FAPESP/Benthic Marine Biodiversity and REVIZEE/South Score - Benthos. Identifications, descriptions and illustrations were made with stereomicroscope, optic and scanning electronic microscope, besides the use of digital camera. The species studied were: Amphicorina sp. n., Amphiglena lindae, Branchiomma luctuosum, B. patriota, Chone sp. n., Demonax cf. microphthalmus, Euchone sp. n., Fabriciola sp. n., Jasmineira sp. n., Kirkiana heterobranchiata, Manayunkia brasiliensis, Megalomma sp. n., Notaulax nudicollis, Notaulax sp. n. 1, Notaulax sp. n. 2, Potamethus sp. n., Pseudobranchiomma minima, P. paraemersoni, P. paulista, Pseudopotamilla sp. n., P. cf. reniformis, Perkinsiana sp. n. e Sabellomma minuta gen. n. From these, 14 are species new to science and 2 are new occurrences to Brazilian coast, besides 2 new genera, one of which already formally described. The genus Sabellomma gen. n. is similar to Bispira, and it is characterized by the presence of unpaired, irregularly-spaced radiolar eye spots, thorax with 4-5 chaetigers, presence of interramal eyespots and companion chaetae. The genus Kirkiana is similar to Perkinsiana,, and its main diagnostic characters are collar dorsally fused to the fecal groove, dorsalmost pair of radioles shorter than the remaining ones in fertile specimens, dorsal lips lacking radiolar appendages and uncini with short handles. Identification keys, complete descriptions and comparisons with closest congeners are provided. (AU) | |
