Hydroid fauna (Cnidaria, Hydrozoa) from the region of Bombinhas, Santa Catarina, Brazil

The benthic hydroid fauna from shallow subtidal zone of six localities in the municipality of Bombinhas (state of Santa Catarina, Brazil) was surveyed and its morphology analysed. Cnidome was also examined when it was necessary for species identification. Twenty five morphospecies were found, from which five (20%) were recorded for the first time in Santa Catarina State and three (12%) were recorded for the first time in the south region of Brazil. There was a 12% and 5.5% increase in the records of benthic hydroid species for Santa Catarina and southern Brazilian coast, respectively.
