Maxilliped palp 4-articulate. Telson entire. Type species . Pratinas ludmilla sp. nov. Etymology . The genus is named for the early Greek poet Pratinas , father of Aristias . Species composition . The genus contains only one species, Pratinas ludmilla sp. nov. Remarks . Chevreux & Bouvier (1892) established the genus Perrierella for the species P. crassipes Chevreux & Bouvier, 1892 which they described as having a maxillipedal palp with a rudimentary fourth article represented by a very small rounded tubercule. Bonnier (1893) recorded material of P. crassipes which he described as having no trace of a dactylopodite [article 4] on the maxillipedal palp, while acknowledging that Chevreux & Bouvier (1892) had recorded a small tubercule. (Bonnier then synonymised P. crassipes with Lysianassa audouiniana Bate 1857 .) We have examined material identified as P. crassipes by Chevreux. There seems to be a very slight extension of the lateral face of article 3, but not of the medial face, on the palp of the left side of the animal but not on the right. This seems identical to the illustration given by Chevreux & Fage (1925 : fig. 12). We cannot interpret this as a fourth article and so establish the new genus Pratinas for a species that has a well-developed article 4 on the maxillipedal palp and an entire telson.
