Abstract: 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, furtherm… Show more

“…The peculiar shape of the penis papilla is distinguished from the other species of Cratera , in which the papilla is nearly horizontal, and even from any other species of Geoplaninae (Carbayo and Almeida 2015). Furthermore, Carbayo and Almeida (2015) have stated that Cratera cuarassu has a large intra-penial cavity as a result of the extension of the widening in the ejaculatory duct.…”

Furthermore, Carbayo and Almeida (2015) have stated that Cratera cuarassu has a large intra-penial cavity as a result of the extension of the widening in the ejaculatory duct. Nevertheless, the inclusion of Cratera cuarassu into this genus is supported by molecular data (Carbayo et al 2013), even though the copulatory apparatus exhibits numerous dissimilarities with the rest of species of Cratera , as male atrium folded and separated from the female one, female atrium without funnel-shape, in addition with the features about the penis papilla above mentioned.…”
