Geoplaninae

Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990) for land planarians which have a broad creeping sole, mouth in the second half of the body, dorsal testes, subepithelial longitudinal musculature well developed and parenchymal longitudinal musculature absent or not well developed. None of these characters is exclusive, however, and cannot be considered a synapomorphy of the group. Nevertheless, phylogenetic studies have revealed that Geoplaninae is indeed a monophyletic group. Currently the land planarians in the subfamily Geoplaninae are grouped in 25 genera:
