Abstract

The genusChoeradoplanaGraff, 1896 encompasses 16 species, most of them found in Brazil. Herein two new species of this genus are described from remnants ofAraucariamoist forests, located in the states of Paraná and Santa Catarina, south Brazil. Both species resemble the type-species of the genus,C.iheringi, showing brownish dorsal surface covered by dark-brown flecks. However, regarding their anatomy, the new species differ fromC.iheringiand other congeners by a long and horizontal disposed permanent papilla. In such aspects, both species resembleC.benyai, but differ from this species, as well as from each other, in details of the prostatic vesicle, ejaculatory duct, and penis papilla.
