Muellerianella
Muellerianella is a genus of delphacid planthoppers comprising seven described species. The genus is notable for its complex reproductive biology, including both biparentally reproducing sexual species and asexual gynogenetic (pseudogamous) triploid forms. Species within the genus are morphologically similar but ecologically differentiated, occupying distinct habitat niches and exhibiting species-specific host plant associations. The Muellerianella complex has been extensively studied as a model system for understanding ecological speciation, hybridization, and the maintenance of species boundaries in the face of incomplete reproductive isolation.
