Checklist of decapods (Crustacea) from the coast of São Paulo State (Brazil) supported by integrative molecular and morphological data: II.

Material examined. Brazil , São Paulo : 1 ♀ , CCDB 4728 , Cananéia , intertidal region in the ferry terminal to Ilha Comprida , coll. T. Davanso & R. Pescinelli , 26.ix.2013 . Distribution. Western Atlantic—Colombia, Venezuela , Brazil ( Pará , Bahia , São Paulo ). Previous records. Cananéia ( Almeida et al . 2014 ). Remarks. Alpheus petronioi belongs to the A. heterochaelis species complex ( Almeida et al . 2014 ). The records of A. heterochaelis from São Paulo made by Luederwaldt (1919) correspond, at least in part, to the A. armillatus complex ( Christoffersen 1984 ; Anker 2012). Other records of A. heterochaelis from São Paulo ( e.g ., Luederwaldt 1929 ; Abreu 1980 ; Mortari & Negreiros-Fransozo 2007 ) and from other regions of the Brazilian coast mentioned by Soledade & Almeida (2013) must be carefully considered because they may include misidentified species. GenBank accession number: CCDB 4728—16S ( KU312975 ), COI ( KU313005 ).
