Book Description
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.

Book Description
"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.

Book Description
The tribe Macrodactylini (Coleoptera: Scarabaeidae: Melolonthinae) is reviewed from southern South America. A total of 13 genera and 33 species were found in the study area consisting of Argentina from Neuquén south and Chile from IV Región de Coquimbo south. The following three new genera are described: Extenuoptyophis, Insimuloissacaris, and Neuquenodactylus. The following 11 new species are described: Ampliodactylus elguetai, Ampliodactylus guinezi, Ampliodactylus inusitus, Ampliodactylus panguipullensis, Extenuoptyophis horridulus, Extenuoptyophis metropolitensis, Insimuloissacaris nahuelbutensis, Issacaris falsa, Issacaris sola, Neuquenodactylus ramus, and Phytholaema fenestra. The species Schizochelus modestus Philippi, 1861 is transferred to the genus Ampliodactylus. Lectotypes are designated for the following five species-group names (species names given in their original combination): Dicrania aeneobrunneaPhilippi, 1861, Modialis prasinella Fairmaire & Germain, 1860, Phytholaema elaphocera Redtenbacher, 1868, Phytholaema herrmanni Germain, 1901, and Schizochelus modestus Philippi, 1861. Neotypes are designated for the following four species-group names (species names given in their original combination): Acanthosternum splendens Philippi, 1861, Areoda mutabilis Solier, 1851, Issacaris petalophora Fairmaire, 1889, and Phytholaema flavipes Philippi, 1861. The genera Modialis Fairmaire & Germain, 1860 and Phytholaema Blanchard, 1851 are here transferred to the tribe Macrodactylini. The species-group names Phytholaema pallida Saylor, 1937 and Phytholaema peccans Blackwelder, 1944 are placed in synonymy with Phytholaema herrmanni Germain, 1901. Descriptions or diagnoses, keys, and distributional data are given for all species.

(= Gymnetis rubida, not Gory & Percheron, 1833); Hoplopyga albiventris (Gory & Percheron, 1833); Hoplopyga brasiliensis (Gory & Percheron, 1833); Hoplopyga liturata (Olivier, 1789); Hoplopygothrix atropurpurea (Schaum, 1841), new country record; Marmarina insculpta (Kirby, 1819), new status, new country record; Marmarina tigrina (Gory & Percheron, 1833), (= Maculinetis litorea Schürhoff, 1937, new synonymy); Neocorvicoana reticulata (Kirby, 1819); Neocorvicoana tricolor (Schürhoff, 1933). Marmarina argentina Moser, 1917 is considered a nomen dubium until a redescription and illustration of the type specimen facilitates the proper identification of this species. The following type specimens were examined: Blaesia atra Burmeister, 1842 (holotype); Gymnetis alauda Burmeister, 1842 (holotype, = G. pantherina); G. bruchi (lectotype, here designated); G. dysoni Schaum, 1844 (paralectotype); G. meleagris Burmeister, 1842 (paralectotype, = G. pantherina); G. perplexa Burmeister, 1842 (holotype, = G. bajula); G. pudibunda (holotype); G. pudibunda porteri Dallas, 1930 (holotype, = G. pudibunda); G. punctipennis Burmeister, 1844 (paralectotype); G. strobeli Burmeister, 1866 (holotype, = Marmarina tigrina); G. platensis Brèthes, 1925 (holotype, = Heterocotinis semiopaca), G. platensis tandilensis Bréthes, 1925 (holotype, = H. semiopaca); Coelocratus rufipennis (Gory & Percheron, 1833) (lectotype, here designated); Trigonopeltastes geometricus Schaum in Burmeister & Schaum, 1841 (lectotype, here designated). Four species are endemic to Argentina (G. bouvieri, G. bruchi, G. cordobana, and G. pudibunda), but records of these species might be expected in the Bolivian and Paraguayan Chaco, as well as in Uruguay. Male parameres, armature of the internal sac of the aedeagus, and the general aspects of adults are presented. An additional six species of Cetoniinae bring the total number in Argentina to 36 species: Euphoria lurida (Fabricius, 1775) (Cetoniini); Cyclidius elongatus (Olivier, 1789) (Cremastocheilini); and Inca bonplandi (Gyllenhall, 1817), Inca clathrata clathrata (Olivier, 1792), Inca pulverulenta (Olivier, 1789), and Trigonopeltastes triangulus (Kirby, 1819) (Trichiini). New records in adjacent countries are four species for Bolivia from a total of 18, 17 of 24 for Paraguay, and two of 10 for Uruguay; 25 species are shared between Argentina and Brazil (three are new records for Brazil).
