Rhysolepis was a genus of Mexican plants in the tribe Heliantheae within the family Asteraceae.

Among their conclusions they proposed to reclassify the genus, dividing and relocating its species in at least eleven genera: Aldama La Llave, Bahiopsis Kellogg, Calanticaria (B.L.

& Panero, Heliomeris Nutt., Hymenostephium Benth., Sidneya E.E.
