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. The eyes contour the anterior region in a single row and posteriorly form several rows, which may spread onto the dorsum, and extend to the posterior end of the body. However, most, if not all, of these characteristics are not exclusive and cannot be considered a
synapomorphy of the group. Some characteristics have also been reverted in some genera. Nevertheless, phylogenetic studies have revealed that Geoplaninae is indeed a monophyletic group. ==Genera==
