Remarks. Morphological variation in the length of antennal peduncles between populations of Pagurus criniticornis from the northern and southern hemisphere raised doubts about its true distribution ( Nucci & Melo 2007 ), and about its taxonomic status. Remarkable individual variations were reported by Forest & Saint Laurent (1968) . A preliminary molecular phylogeny revealed close relationship among South American species of the “ provenzanoi ” clade, including P. criniticornis ( Olguín & Mantelatto 2013 ) . Sequences accession numbers (GenBank): CCDB779—16S ( DQ369947 ), CCDB 463—COI ( MF490059 ) ( Mantelatto et al. 2006 , 2018).
