The parentage of Catasetum ×dunsterville, a natural hybrid or nothospecies, formally proposed in 1989 from the vicinity of Puerto Ayacucho, Amazonas state, Venezuela, was confirmed via artificial hybridization. The originally proposed putative parents were Catasetum pileatum and C. discolor. In nature, both species are pollinated by the same male Euglossine bees, Eulaema meriana and E. cingulata, and the two orchids are found in close proximity and have overlapping flowering seasons: the hybrid is relatively common. The artificial hybrid took 44 months (January 2014–September 2017) from the time seeds were planted to the first flowering.
