Milne-Edwards, 1879 [in A. Milne-Edwards, 1873 – 1880 ] Coenophthalmus tridentatus A. Milne-Edwards, 1879: 237 , pl. 42, fig. 2. Material examined. Brazil , São Paulo : 1 j, CCDB 1396 , Ubatuba , Ilha Anchieta , colls. F. Mantelatto & R . Biagi, 01.v.2002 . Distribution. Western Atlantic—Brazil (Rio de Janeiro, São Paulo, Santa Catarina, Rio Grande do Sul), Uruguay , and Argentina ( Boschi 1964 ; Coelho & Ramos 1972 ; Melo 1990 , 1996 ). Remarks. Previous records in São Paulo include Ilha Anchieta ( Melo 1990 ). This species is found in areas under the influence of the Malvinas Current in warm temperate waters of subtropical origin ( Melo 1990 ). Thus, it is possible that C. tridentatus do not occur in the sampled sites because of the influence of other currents or due to the lack of favorable conditions (cold temperature) for its establishment in the environment. The new taxonomic rearrangement moved this species to the family Polybiidae ( Spiridonov et al. 2014 ) .
