Abstract

<i>Macrobrachium pantanalense</i> Dos Santos, Hayd & Anger, 2013 <p>(Figs. 4E, 5)</p> <p> <b>Material examined</b>. Brazil, Minas Gerais: 95 spec. (6 ♀ ov.), LEEACC 0001, Nova Ponte, coll. A.C. Almeida, A.C.F. Porto & M.S. de Oliveira, VII.2015 – VI.2016; 5♂, 5♀, LEEACC 0034, Uberlândia, coll. A.C. Almeida & M.C. Cunha, VII–VIII.2017; 4♀, LEEACC 0033, represa de Miranda, rio Araguari, Uberlândia, coll. R. C. Silva & G.B. Jacobucci IV.2012 – V.2013; 1♀, LEEACC 0035, rio Araguari, Tupaciguara, coll. G.B. Jacobucci 03.II.2008; 2 spec., LEEACC 0036, rio Araguari, Uberlândia, coll. G.B. Jacobucci 10.VII.2009; 5 spec., LEEACC 0037, rio Araguari, Uberlândia, coll. G.B. Jacobucci 05.IX.2010; ♀ ov, CCDB 2641, represa Miranda, Uberlândia, coll. H. Grande, 31.III.2009; 2♀., CCDB 2953, Tupaciguara, coll. G.B. Jacobucci, 2006.</p> <p> <b>Distribution</b>. Brazil (Mato Grosso do Sul, Minas Gerais, São Paulo) (Vergamini <i>et al</i>. 2011; Santos <i>et al</i>. 2013; Weiss <i>et al</i>., 2015; Calixto-Cunha <i>et al</i>. 2021).</p> <p> <b>Previous records in Minas Gerais</b>. The first record of the species in Minas Gerais by Calixto-Cunha <i>et al</i>. (2021) indicates that <i>M. pantanalense</i> has expanded its distribution outside the Pantanal region.</p> <p> <b>Remarks</b>. The genetic distance and the haplotype diversity between <i>M. pantanalense</i> population from Pantanal and <i>M. amazonicum</i> population from the Amazon Delta obtained by Weiss <i>et al</i>. (2015) reinforce the hypothesis of these being distinct species. The reproductive isolation observed by Nogueira <i>et al</i>. (2020) appears to be another piece of evidence to support this hypothesis.</p>Published as part of <i>Jacobucci, Giuliano Buzá, Bueno, Alessandra A.
