The Dichotomius sericeus species group of the subgenus Luederwaldtinia is reviewed. This comprises eight endemic to South American Atlantic forests, Caatinga and associated areas Brazil, Paraguay Argentina: (Harold, 1867); irinus laevicollis (Felsche, 1901); schiffleri Vaz-de-Mello, Gavino Louzada, 2001; guaribensis sp. nov.; gilletti nov; iannuzziae catimbau nov.

The genus Scybalocanthon Martínez, 1948 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini) is revised and now consists of 23 valid species. Eight new species are described: S. acrianus species, adisi arnaudi chamorroi federicoescobari haroldi martinezi papaxibe uniplagiatus (Schmidt, 1922) combination placed in the for first time. following previously assigned to here Canthon Hoffmannsegg, 1817: arcabuquensis (Molano & Medina, 2010) combination, balachowskyi (Martínez Halffter, 1972)...

Abstract Dichotomius ( Selenocopris ) is amongst the most diverse subgenera of Hope, 1838. Due to scarcity material and logistical problems experienced by previous authors access type specimens, available taxonomic information for batesi group mainly short superficial original descriptions its species. In this paper, we provide a revision all species assigned comparative study with belonging taxonomically related groups, namely: agenor, geminatus, inachus, carbonarius , lucasi . The...

Within the subgenus Dichotomius (Selenocopris) Burmeister 1846, D. nisus (Olivier, 1789) and superbus (Felsche, 1901) had been historically arranged in "Nisus" section by Luederwaldt, however, according to revised classification of subgenus, two species now belong different groups. In this paper, taxonomic history concerning once included Luederwaldt is discussed. The following new synonyms are proposed: Pinotus taunayi (Luederwaldt, 1931) as a subjective synonym geminatus (Arrow, 1913),...

The globulus species group of Dichotomius (Selenocopris) is revised. In total, the comprises 10 species, which nine were previously part batesi group: D. benesi Vaz-de-Mello and Nunes, 2016; danieli Kohlmann Solís, 1997; favi femoratus Howden Young, 1981; fortepunctatus (Luederwaldt, 1923); gamboaensis (Felsche, 1901); ocellatopunctatus rodrigoi 1997. Pronotal punctation, elytral microsculpture new characters male genitalia are used to improve diagnosis. A Colombian berthalutzae sp. nov.,...

This paper provides a synopsis of the South American genus Diabroctis Gistel, 1858. Five species are assigned to genus. The type D. mimas is widely distributed and shows considerable morphological variation in male secondary sexual characters. A substantial number geographic data used provide an updated diagnosis this species, describe intraspecific variation. new Brazilian described as pseudomimas sp. nov. , which has been recognized among specimens confused with (Linnaeus) entomological...

The monospecific subgenus Dichotomius (Homocanthonides) is revised and its single species, (H.) smaragdinus (Perty, 1830) redescribed distinguished from other species. a polymorphic species distribution comprises the Brazilian Cerrado. For first time, morphological variation male genital organ are described illustrated. We believe that this might be endangered due to extensive deforestation of Cerrado by agricultural pasture expansion. Thus, we highlight importance preserving very unusual

Metopiellus Raffray, 1908 is a genus of South American rove beetles typically found in tropical humid forests. Here we describe new cryptic species from Eastern Amazon, northern Brazil, crypticus Asenjo sp. nov. , and its major morphologic diagnostic features, which were photographed illustrated. In addition, bring the complete mitochondrial genome sequence M. position within phylogenetic context family, including previously available mitogenomes Staphylinidae species.

The oil palm is an economically important crop cultivated in the North of Brazil. Damage caused by insects one main causes reduced productivity for palm. Before this research, only beetles family Curculionidae were considered to be pests However, first time, we report on damage a giant rhinoceros beetle plantations Pará, was identified as Golofa claviger (Linnaeus, 1771), which has single record Brazil (Pará) but widely distributed South America. species occurs unprecedentedly high abundance...

Here we present a taxonomic treatment for the Brazilian species of Syrbatus (Reitter, 1882), including description three new ( moustache Asenjo & Valois sp. nov. , obsidian and superciliata ) from Quadrilátero Ferrífero (Minas Gerais, Brazil). In addition, designated lectotypes species-group 2, centralis (Raffray, 1898), hetschkoi 1888), hiatusus transversalis trinodulus (Schaufuss, 1887), besides recognizing holotype brevispinus bubalus grouvellei 1898). The mitochondrial genomes...

The South American genus Scatonomus is revised. Diagnoses, descriptions, distribution data, an identification key and illustrations are provided for the 11 species assigned to genus, including new canhedoae sp. nov., mitzae nov. foresti barbatus, which has been historically regarded as a variety of S. fasciculatus, revalidated. A synonymy, xanthopygus Pereira with chalybaeus Erichson, proposed. lauropalui Vulcano transferred Anomiopus Westwood, 1842. Lectotypes designated viridis viridis,...

Golinca trevisani Valois & Silva, new species (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini: Incina) from Ouro Preto do Oeste, Rondônia, and Amazonas, Brazil is described, representing the first record of genus for Brazil. Diagnosis, illustrations key morphological characters, male genitalia description in genus, a identification four are provided.

Abstract The third‐stage larva of Golofa claviger (Linnaeus, 1771) is described for the first time based on specimens collected in municipalities Acará and Tailândia, Pará state, northern Brazil. A diagnosis, updated description female, key known larvae Hope, 1837, illustrations morphological characters are also given. Furthermore, taxonomic literature females immature stages Dynastini from New World tabulated to provide an overview genera possible historical trends.
