Intertidal species of Branchiomma Kolliker and Pseudobranchiomma Jones (Polychaeta : Sabellidae : Sabellinae) occurring on rocky shores along the state of Sao Paulo, southeastern Brazil
Intertidal species of Branchiomma Kolliker and Pseudobranchiomma Jones (Polychaeta: Sabellidae: Sabellinae) occurring on rocky shores along the state of Sao Paulo, southeastern Brazil. Zoological Studies 45(4): 586-610. Four species of sabelline sabellids collected intertically on rocky shores off the State of Sao Paulo are herein described. Among these species, Pseudobranchiomma paraemersoni sp. nov., P. paulista sp. nov., and Branchiomma patriota sp. nov. are new to science and B. luctuosum Grube is a new occurrence for the Brazilian coast. Pseudobranchiomma paraemersoni sp. nov. is a small species, with 4-6 thoracic chaefigers and 3 or 4 pairs of lateral serrations on the radiolar flanges. Pseudobranchiomma paulista sp. nov. is a relatively large species, with 6-10 thoracic chaetigers; and 10-19 pairs of lateral serrations on the radiolar flanges. Branchiomma patriota sp. nov. has an unpaired basalmost row of stylodes and long and short stylodes irregularly distributed along the radioles, with the longest up to 4 times as long as the shortest. Comparisons with the closest congeners are provided for each of these new species, and a possible synapomorphy for Pseudobranchiomma is proposed based on the pigmentation of the crown in live material. Some speculations about the presence of B. luctuosum in Brazil are made, as we consider it to be an invasive species, as has been reported to have occurred before in Italy.
