The Mesoamerican Genus <I>Yaaxkumukia</I>: Biogeography and Descriptions of New Species (Coleoptera: Rutelidae)

Abstract

The until now monospecific genus Yaaxkumukia Morón & Nogueira (Coleoptera: Scarabaeoidea: Rutelidae: Anomalinae: Anomalini) occurs in the south of Mexico, Guatemala, and Honduras. Two new species Yaaxkumukia conabioi sp. nov. and Yaaxkumukia moroni sp. nov. are described, and the type species of the genus, Yaaxkumukia ephemera Morón & Nogueira, is redescribed. A key of the species of Yaaxkumukia is provided. Collection records show that the species of Yaaxkumukia are associated with medium-elevation cloud forest, and their scarce mobility together with the fragmentation of this ecosystem threatens their populations. The biogeography of the genus also is discussed.
