A monographic revision of the Neotropical dung beetle genus Sylvicanthon Halffter & Martínez, 1977 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini), including a reappraisal of the taxonomic history of ‘Canthon sensu lato’

“…In several dung beetle community inventories carried out in the Amazon region, S. proseni was one of the most abundant species (e.g., Noriega et al 2007a: in Meta, Colombia, it corresponded to 4.66% of the collected specimens; Korasaki et al 2012: Amazonas, Brazil, 5.6%;Vaz-de-Mello 1999: Acre, Brazil, 23%;Noriega et al 2008: Amazonas, Colombia, 29.9%;Carpio et al 2009: Sucumbíos, Ecuador, 55%). This species seems to be absent only in grasslands and agricultural fields, but, where some small patch of forest is left standing or there is secondary regeneration, S. proseni can be found (Vaz-de-Mello 1999;Noriega et al 2007a;Korasaki et al 2012), including river floodplain areas (Escobar 2000b;Nunes et al 2014). These observations clearly show the species' flexibility and its considerable resistance against anthropic impact.…”

“…29), synonymized C. aequinoctialis and G. proseni without presenting, however, the reasons for that act, although it is reasonable to imagine they did so based on the arguments given by Martínez et al (1964). In this way, except for some recent faunistic inventories that treated C. proseni as a valid species (e.g., Vaz-de-Mello et al 2011b;Korasaki et al 2012;Nunes et al 2014;Chamorro et al 2018), these two names have remained in synonymy ever since. Next, we present evidence that, in our view, supports the present revalidation of S. proseni and demonstrates its independence from S. aequinoctialis.…”

“…Sylvicanthon proseni was mainly collected using human faeces as bait and it seems to be preferably coprophagous (Martínez et al 1949;Vaz-de-Mello 1999;Noriega et al 2007aNoriega et al , 2008Figueroa & Alvarado 2011;Korasaki et al 2012;Nunes et al 2015; and information from specimen labels). Some individuals collected in Porto Velho (Rondônia, Brazil), however, were caught using pitfall traps baited with chicken meat and rotten bananas.…”

Characterization and chromosomal mapping of the DgmarMITE transposon in populations of Dichotomius (Luederwaldtinia) sericeus species complex (Coleoptera: Scarabaeidae)

“…Cytogenetic studies have been carried out in only 18 of the 165 described Dichotomius species, including molecular cytogenetics studies in 15 species ( Cabral-de-Mello et al. , 2008 , 2011a ,b; Silva et al , 2009 ; Korasaki et al , 2012 ; Xavier et al , 2014 ). This genus presents groups of closely related species ( Sarmiento-Garcés and Amat-Garcia, 2009 ), including Dichotomius ( Luederwaldtinia ) sericeus complex (Coleoptera: Scarabaeidae).…”

Diversidade de besouros rola-bosta (Coleoptera : Scarabaeidae : Scarabaeinae) em duas unidades de conservação do Cerrado do Brasil central

“…No Nordeste (Reserva Biológica Guaribas, na Paraíba, em Mata Atlântica e Tabuleiro Nordestino) foram coletados 3.533 indivíduos, 5 tribos e 29 espécies (Endres et al, 2007). No Norte, em Benjamin Constant, no Amazonas, foram coletados 6.792 indivíduos, 6 tribos e 63 espécies (Korasaki et al, 2012). No Centro-Oeste (Chapada dos Guimarães, Mato Grosso, em formações de savana, mata de Cerrado e Chaco) foram coletados 17.635 indivíduos, 6 tribos e 98 espécies (Daniel et al, 2014).…”
