We propose the new nothogenus, x Cohnlophiaris Cetzal & Balam (Cohniella x Lophiaris) based on a natural intergeneric hybri, x Cohnlophiaris quintanarooensis Cetzal & Carnevali (Cohniella ascendens x Lophiaris oerstedii) from a locality in Quintana Roo, Mexico, which is here described and illustrated. The new nothospecies is vegetatively similar to C. ascendens but the flowers show intermediate characters between the putative parents. x Cohnlophiaris quintanarooensis is similar to C. ascendens by having yellow petals and sepals with brown or reddish spots, transversely subquadrate central lobe, central keel parallel to the proximal and distal teeth, and pollinarium of Cohniella type. On the other hand, is it similar to L. oerstedii in the papillose abaxial surface of petals and sepals, the oblong lateral lobes of the labellum, the subquadrate column base, the pentagonal cavity stigmatic and the pink clinandrium. A key to diagnose the new intergeneric hybrid and its putative parents, a comparative figure and a map showing their geographical distribution are provided.
