Book excerpt: "Abstract: The phylogeny of Tomarus Erichson, 1847 (Coleoptera: Scarabaeidae: Dynastinae: Pentodontini) was explored by parsimony using morphological characters to approach its taxonomic and nomenclature problems. The genus was not supported as a monophyletic group, and the recovered lineages did not match at all any of the previously known classifications. Three different lineages and six monophyletic groups were recovered, which could be treated as independent genera. However, the classification proposed here is as conservative as possible concerning to the creation of many new names and generic taxa. Thus, four genera are now recognized: Euligyrus Casey, 1915 new status (2 species), Ligyrus Burmeister, 1847 revised status (18 species, including Oxygrylius Casey, 1915 new synonymy), Proculigyrus new genus (1 species), and Tomarus Erichson, 1847 revised status (18 species). Three subgenera are recognized for the genus Ligyrus: Anagrylius Casey, 1915 revised status (2 species), Ligyrodes Casey, 1915 revised status (3 species), and Ligyrus revised status (13 species). A complete taxonomic treatment is presented for each genus, including descriptions, keys, and occurrence maps. A revised status is presented for the following species: Ligyrus (Ligyrus) nasutus (Burmeister, 1847), T. amazonicus (Arrow, 1914), and T. gyas Erichson, 1848. Lectotypes are designated for Bothynus neglectus LeConte, 1847, L. amazonicus Arrow, 1914, L. bryanti Rivers, 1891, Scarabeus fossor Latreille, 1813, S. relictus Say, 1825 T. gyas, T. maimon Erichson, 1847, and some synonyms of L. sallaei Bates, 1888 (Ligyrodes propinquus Casey, 1915 and Ligyrodes aztecus Casey, 1915), S. gibbosus DeGeer, 1774 (Bothynus morio LeConte, 1847, L. californicus Casey, 1909, and L. spissipes Casey, 1909), S. relictus (Ligyrodes parviceps Casey, 1915 and Ligyrodes quadripennis Casey, 1915), and S. bituberculatus Palisot de Beauvois, 1811 (Ligyrus maximus Arrow, 1913 and Ligyrus latus Arrow, 1914). Ligyrus patagonus Steinheil, 1874 is a new synonym for L. rubripes Boheman, 1858. Type species are designated for the synonyms Grylius Casey, 1915 and Ligyrellus Casey, 1915. New combinations (new combination) are presented for: Euligyrus ebenus (De Geer, 1774), E. similis (Endrödi, 1968), Ligyrus (Anagrylius) moroni (López-García & Deloya, 2019), L. (Ligyrus) paranaensis (López-García & Deloya, 2019), L. (Ligyrus) peninsularis (Casey, 1915), L. (Ligyrus) spinipenis (Neita & Ratcliffe 2017), and Tomarus amazonicus. Ligyrus (Ligyrus) allonasutus new species is described to include populations of T. nasutus from western Mexico to Panama. Phylogenetic and taxonomic value of mouthparts, elytro-tergal stridulatory apparatus, and male genitalia is discussed along with a description of the biogeographic patterns of distribution for each genus Page 4. Keywords: Euligyrus, Ligyrus, Proculigyrus, white grubs, Pentodontini, phylogeny, nomenclature, keys.

Available in PDF, EPUB and Kindle. Book excerpt: The scarab beetle tribe Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae) includes 15 genera and approximately 500 species that are distributed primarily in the New World. Species in the group are important pollinators of aroids, palms, and lilies, some are agricultural pests, and a few are invasive in areas where they have been introduced. Evolutionary relationships of the group have not been examined, and monophyly of the tribe and relationships of genera have not been addressed. As a result, the classification remains unstable, and there is no foundation with which to interpret evolutionary patterns. To provide an evolutionary framework, a phylogenetic analysis using 77 adult morphological characters was performed. Representatives from all recognized cyclocephaline genera were examined as well as taxa that have historically been included in the tribe. Outgroups included exemplars from the dynastine tribes Oryctini, Oryctoderini, and Pentodontini and the ruteline tribes Anomalini and Rutelini. Based on the analysis, Cyclocephalini, as currently circumscribed, does not constitute a monophyletic lineage. Thus, the current classification does not reflect evolution, and revision is required. Based on strong character support, the genera Eriocelis and Stenocrates are not a part of the new cyclocephaline clade while genera Parapucaya and Neohyphus are members of the new Cyclocephalini.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The eight species in the genus Tomarus Erichson (Coleoptera: Scarabaeidae) in Argentina, Chile, and Uruguay are reviewed. Tomarus roigjunenti new species and Tomarus spinipenis new species are described from Argentina. We include a key to species, representative habitus illustrations for all species, character illustrations, and distribution maps for each, as well as commentary about the natural history and distributions for each species. Diagnostic characters are discussed for each species, and species relationships are hypothesized based on the analysis of internal and external morphological characters. The male of T. bidentulus (Fairmaire) is described for fi rst time. The following taxonomic changes are made: Tomarus guianucai Dechambre and Lumaret, 1985 is a new junior synonym of Tomarus rubripes (Boheman, 1858), which was formerly and incorrectly cited as occurring in Argentina.
