Both were united by the presence of multiple eyes along the body and distinguished from each other by the presence of dorsal testes in Geoplaninae and ventral ones in Caenoplaninae.[2] However, molecular studies revealed that this classification was artificial and that Caenoplaninae were actually closely related to Rhynchodeminae. Therefore, recent classification puts the former subfamilies Rhynchodeminae and Caenoplaninae as tribes, respectively Rhynchodemini and Caenoplanini, within an expanded subfamily Rhynchodeminae. This group is supported by molecular phylogeny, but there are no known synapomorphies.[3] GeneraCurrently the tribe Caenoplanini comprises the following genera:
