Selenacentrus wallacei
Selenacentrus wallacei is a treehopper species in the family Membracidae, described by Morris and Dietrich in 2016. It represents the sole species of the monotypic genus Selenacentrus. The species was discovered among mislabeled specimens in multiple museum collections and is known from Texas and northern Mexico. Its taxonomic placement required the establishment of a new genus due to unique morphological characteristics that do not align with any recognized tribes within the subfamily Centrotinae.
