Argaplana is a genus of land planarians, the only member of the tribe Argaplanini in the family Rhynchodeminae.

[1] The tribe Argaplanini is characterized by pigment cup eyes in multiple rows around the body's front tip that continue to the back end along the dorsal side, ventral testes and efferent ducts, tripartite cutaneous musculature, cutaneous longitudinal muscles in bundles, a lack of a ring zone, and a creeping sole that is over half of the body width.

[2] The genus Argaplana is characterized by a small, tapered body with a mouth at the mid-third of the body, muscles that are longitudinal, circular, and helical, a penis lacking papilla, ovovitelline ducts that unite then enter the female genital canal ventro-posteriorly, and a lack of a resorptive bursa, adenodactyls and a viscid gland.

[2] Argaplana ranuii is a cream-white color with a slightly paler creeping sole.

[2] The generic name of Argaplana, and the tribe name by extension, are derived from Argus Panoptes, the many-eyed giant of Greek mythology, and the Latin word plana, meaning "planarian".
