Two new land planarian species, collected in the State of Rio de Janeiro, Brazil, are described. Their external aspect is similar to that of Imbira marcusi Carbayo et al., 2013 and Pseudogeoplana theresopolitana (Schirch, 1929), respectively. The analysis of the internal organs, however, revealed they belong to the genus Cratera. The male copulatory organs of one species is very different from any other geoplaninid, for the penis papilla holds a large, distal cavity receiving the ejaculatory duct and, furthermore, the papilla projects vertically downwards from the roof of the male atrium. Thus we consider it as a new species, Cratera cuarassu sp. nov. The second species differs from its congeners in that the dorsal insertion of the penis papilla is anterior to the ventral one, and in that the female atrium is narrowed in the anterior portion. The species was found in the type locality of Pseudogeoplana theresopolitana (Schirch, 1929) and compares well with it in the external features. However, since its internal organs are unknown and the type material of the species is seemingly lost, we describe it as Cratera anamariae Carbayo, sp. nov.

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.
