Abstract

Mimarachnidae is an enigmatic Cretaceous planthopper family with remarkable taxonomic and morphological diversity documented from the mid-Cretaceous Kachin amber of Myanmar. We expand knowledge of the genus Dachibangus Jiang, Szwedo & Wang, 2018 through the description of three new species: D. pallidus sp. nov., D. partialis sp. nov., and D. pouilloni sp. nov. These new species permit an emended diagnosis of Dachibangus and support the synonymization of the recently described genus Trichotomus Wang, Zhuo, Luo & Chen, 2025 with Dachibangus, resulting in the new combination Dachibangus zhuoyuanshengi comb. nov. Our study indicates that the branching pattern of MP is more variable than previously recognized and cautions against its use as a diagnostic feature.
