A new southern Atlantic cryptic marine shrimp species of Acetes (Decapoda, Sergestidae).

ABSTRACT: A recently published molecular phylogenetic analysis, focusing on selected Western Atlantic subspecies of Acetesamericanus Ortmann, 1893 and allies, was inconclusive about relationships among these members. This previous study found three groups that split into two distinct lineages: Acetesamericanus (Brazil 1) (= A.americanus sensu stricto) and Acetesamericanus (Brazil 2) + A.americanus (USA). Combined morphometry and molecular analyses applied to members of the group Acetesamericanus (Brazil 2) revealed a new unidentified species genetically related to the A.americanus representatives. However, at that time, no conclusive morphological characters were found to identify it. In the present study, following an in-depth morphological analysis
