Abstract / Description:The millipede Pycnotropis epiclysmus Hoffman, 1995 (Diplopoda: Polydesmida: Platyrhacidae) is frequently found in Central Amazonian white- and mixed-water inundation forests along the Solimoes-Amazon River near Manaus, Brazil. It also inhabits non-flooded disturbed forest areas adjacent to this river. Populations from both biotopes were genetically studied. The specific pPeP172 satellite DNA family identified in P. epiclysmus has been analyzed in order to elucidate the systematic rank of morphologically indistinguishable individuals from the different habitat types. Nucleotide sequence data, sequence variability and copy number estimates of the pPeP172 satellite DNA do not discriminate the respective populations into genetically different ecotypes. The study of enzyme variability, however, revealed genotypic differences among the three populations: the populations from two geographically more distant inundation forests are genetically rather similar; and the geographically closer populations, one found in a non-flooded and the other in an inundation forest, have a genetic distance which is of similar magnitude to that of the two geographically more distant populations. The genetic data suggest that individuals from different habitats belong to populations of a single species. Genotypic structuring among and within local populations indicates processes of genetic differentiation which can be the result of the migration ability of this millipede.
