Rhynchodeminae is a subfamily of
land planarians
with a worldwide distribution.
Phylogeny and systematics
Based on morphological evidence, especially the presence of a single pair of eyes, the subfamily Rhynchodeminae initially encompassed only the species in the current tribe Rhynchodemini and was considered the sister group of subfamily Microplaninae.[2] The remaining tribes were considered closely related to the subfamily Geoplaninae due to the presence of multiple eyes along the body.
However, molecular studies revealed that this classification was artificial and that the Rhynchodeminae were closely related to
synapomorphies.[3]
