Notes. The species was described by Brolemann (1910) and is distributed in the French Pyrenees, and in northern Spain. Body length is 13-16 mm, the gonopods may resemble those of Polydesmus inconstans Latzel, 1884 (see Demange 1981: 125, figs 170- 171). It differs from P. inconstans in having a row of teeth dorsally on the endomere and if this character was not observed, probably misidentified as P. inconstans ( Fig. 19 ) in the literature. It differs from species of the genus Propolydesmus with the presence of the well-developed exomere and endomere - with seminal groove and solenophore-pulvillus extended onto. These characters conform to those of the genus Polydesmus Latreille, 1802/03, and with its type species Polydesmus complanatus Linnaeus, 1761. Propolydesmus racovitzai is here transferred back to Polydesmus .
