Abstract

BITAR, Alberto  and  MORON, Miguel Ángel. Revision and phylogenetic analysis of the genus Xyloryctes (Coleoptera: Melolonthidae: Dynastinae: Oryctini). Rev. Mex. Biodiv. [online]. 2014, vol.85, n.3, pp.753-796. ISSN 2007-8706.  https://doi.org/10.7550/rmb.42654.

The thirteen species of Xyloryctes distributed from southeastern Canadá to Panamá, are reviewed and figured, including the revalidation of X. faunus and the description of X. orientalis n. sp. Following the phylogenetic analysis based on 52 morphological characters of 13 species, the phylogenetic hypothesis confirming Xyloryctes as a monophyletic group is proposed, but relationships with other genera of Oryctini remains unresolved. All the known species are redescribed, their distribution in Mexico is updated and a key to the species is included. Figures of the mesocoxal stridulatory structures are included.

Keywords : taxonomy; Distribution; stridulatory structures.
