| Abstract | |
Since 2008 there have been many records in Europe (British Isles, Spain, France, Italy) of a large terrestrial planarian morphologically very similar to the Brazilian species Obama marmorata. Sequences of mitochondrial (Cox1) and nuclear (18S, 28S, ITS-1 and EF) genes from European specimens and some from Brazil indicate that they belong to a species different from that of other specimens also collected in Brazil. Moreover, the phylogenetic results show that they are not sister-species. Histological sections of both Brazilian and European specimens reveal subtle morphological differences between the two species. Obama marmorata is confined to Brazil, and the second, herein described new species, Obama nungara sp. nov., is found in Brazil and Europe. These cryptic species may be syntopic in areas in Brazil. The new species occurs in human-modified environments both in Brazil and in Europe. We also conclude that the specimens from Spain and Argentina identified previously as Obama marmorata belong to the new species.
