Peisos petrunkevitchi Burkenroad, 1945: 554 .

Material examined. Brazil, São Paulo: 1 ♀, CCDB 5932 , Ubatuba, coll . R. Costa , 11.ii.2013 ; 14 ♀, CCDB 4958 , Ubatuba, colls . R. Costa et al., 28.xi.2013 ; 12 ♀, CCDB 4959 , Ubatuba, colls . R. Costa et al., 28.xi.2013 ; 1 ♂, 6 ♀, CCDB 4940 , São Vicente, coll. A. Castilho, 3.ix.2012 .

Distribution. Western Atlantic— Brazil (Rio de Janeiro, São Paulo, Paraná, Santa Catarina, Rio Grande do Sul), Uruguay, and Argentina ( Boschi 1979; Pérez Farfante & Kinsley 1997; D’Incao & Martins 2000; Costa et al. 2003; Robert et al. 2007; Boos et al. 2012; Mantelatto et al. 2018).

Remarks. Previous records from the coast of São Paulo include Ubatuba ( D’Incao & Martins 2000; Costa et al. 2003; Simões et al. 2012; Mantelatto et al. 2018); it is usually captured in low temperatures (<20 °C) ( Simões et al. 2013). Although it may be captured incidentally as bycatch of some commercial shrimps, this species is not considered as endangered or under threats ( Costa & Simões 2016). The monotypic genus Peisos had its phylogenetic status tested in relation to other sergestids genera Sicyonella Borradaile, 1910 and Acetes ( Vereshchaka et al. 2016a) . These authors combined all species of Acetes and P. petrunkevitchi into a single monophyletic genus and consider Peisos as a junior synonym of Acetes ( Vereshchaka et al. 2016a) . Peisos petrunkevitchi with A. a. americanus are sympatric species in southeastern and southern Brazil, which has led to mistaken identifications on previous records ( D’Incao & Martins 2000). Currently, Peisos petrunkevitchi is still accepted (WoRMS 2022), and considering the non-consolidated opinion among carcinologists and to avoid taxonomic instability, we maintained nomenclature here until there is a consolidated taxonomic treatment of the genus. Sequences accession number (GenBank): CCDB 4940—16S ( KX196598 ), COI ( KX196540 ) ( Mantelatto et al. 2018).
