“…These investigations mainly focused on morphology, feeding habits, and ecological function [ 24 , 25 , 26 ], besides species composition, richness, and abundance of dung beetles, while taking into consideration altitudinal and successional gradients, as well as seasonal variations (climate) [ 27 , 28 ]. Moreover, these studies illustrated that dung beetles can be used as biodiversity indicators for both undisturbed and disturbed areas, and thus are potential identifiers of highly disturbed ecosystems [ 29 , 30 ].…”

This study evaluated the effects of land-use change (L-UCH) on dung beetle community structure (Scarabaeinae) in a disturbed dry ecosystem in southern Ecuador. Five different L-UCH classes were analyzed by capturing the dung beetle species at each site using 120 pitfall traps in total. To determine dung beetle abundance and diversity at each L-UCH, a general linear model (GLM) and a redundancy analysis (RDA) were applied, which correlated environmental and edaphic conditions to the community structure. Furthermore, changes in dung-producing vertebrate fauna were examined, which varied significantly between the different L-UCH classes due to the specific anthropogenic use or level of ecosystem disturbance. The results indicated that soil organic matter, pH, potassium, and phosphorus (RDA: component 1), as well as temperature and altitude (RDA: component 2) significantly affect the abundance of beetles (GLM: p value < 0.001), besides the food availability (dung). The highest abundance and diversity (Simpson’s index > 0.4, Shannon-Wiener index > 1.10) was found in highly disturbed sites, where soils were generally more compacted, but with a greater food supply due to the introduced farm animals. At highly disturbed sites, the species Canthon balteatus, Dichotomius problematicus, and Onthphagus confuses were found specifically, which makes them useful as bio-indicators for disturbed dry forest ecosystems in southern Ecuador.

“…Para o Nordeste brasileiro, poucos são os trabalhos encontrados na literatura com Coleoptera. As pesquisas têm se concentrado em amostragens com a utilização de armadilhas Malaise (Iannuzzi et al, 2003;Maia et al, 2003;Iannuzzi et al, 2006), armadilhas de solo, Malaise e guarda-chuva entomológico (Vasconcellos et al, 2010), armadilhas de luz (modelo Luiz de Queiroz), rede entomológica e/ou armadilhas com iscas para Cerambycidae (Nascimento & Bravo, 2014;Nascimento et al, 2016) e com iscas para escarabeídeos (Hernández, 2005(Hernández, , 2007Lopes & Louzada, 2005;Lopes et al, 2006;Liberal et al, 2011;Salomão et al, 2014;Salomão & Iannuzzi, 2015;Silva et al, 2017;Vieira et al, 2017). No entanto, tais pesquisas são restritas a poucas famílias de Coleoptera.…”

RESUMO Os besouros apresentam grande diversidade taxonômica e funcional, no entanto, para a Região Nordeste, especialmente para a porção com vegetação de Caatinga, o conhecimento da fauna de Coleoptera é muito restrito. Por se tratar de uma região com grande diversidade de paisagens, torna-se necessário conhecer a coleopterofauna que ocorre nas diferentes fitofisionomias, buscando com isso abranger a variabilidade espacial encontrada nessa região xérica. Diante disso, o objetivo deste estudo foi realizar um levantamento das espécies de besouros no Semiárido paraibano. As coletas foram realizadas semanalmente durante quatro anos (2009-2013) utilizando uma armadilha Malaise por fitofisionomia, sendo amostrada uma área com vegetação xerófila e outra com mata ciliar. Foram coletados 6.567 indivíduos pertencentes a 383 espécies e 42 famílias de Coleoptera. Chrysomelidae (78 spp.), Curculionidae (57 spp.) e Cerambycidae (28 spp.) foram as famílias mais ricas. Em relação às mais abundantes, Chrysomelidae (30,4% dos indivíduos), Curculionidae (8,3%) e Tenebrionidae (7,7%) se destacaram. Foi verificado um elevado número de singletons e doubletons, apesar do prolongado período amostral, indicando que deve haver ainda muitas espécies a serem registradas na área de estudos. Nossos resultados demonstram uma rica fauna de besouros na região semiárida estudada e fornece uma lista de besouros de ocorrência no Semiárido paraibano, com novos registros de espécies para o estado e contribui assim com o conhecimento da diversidade de Coleoptera no Nordeste do Brasil.

“…The Neotropical genus Deltochilum Eschscholtz, 1822 is a common part of the dung beetle community, mainly in South America. Some studies have found Deltochilum to be one of the most abundant genera of the Coleoptera community [ 5 ], with some species being some of the most abundant in the Scarabaeinae community [ 6 , 7 ]. Usually, the number of species of Deltochilum at a given locality varies between three [ 6 ] to seven [ 7 ], but it can reach 10 (pers.…”

Towards a comprehensive taxonomic revision of the Neotropical dung beetle subgenus Deltochilum (Deltohyboma) Lane, 1946 (Coleoptera: Scarabaeidae: Scarabaeinae): Division into species-groups

Deltochilum Eschscholtz, 1822 is perhaps the most speciose genus of the tribe Deltochilini sensu Tarasov & Dimitrov (2016) (Scarabaeidae: Scarabaeinae) and has been traditionally divided into eight subgenera. Among them, the subgenus Deltohyboma Lane, 1946, is the most speciose with 47 species, five of which are described here (D. genieri sp. nov., D. gilli sp. nov., D. susanae sp. nov., D. bolivariensis sp. nov. and D. inesae sp. nov.), and at least 165 species still undescribed. Due to the large number of species, and for practical purposes, the subgenus is here divided into 19 species-groups, with D. inesae sp. nov. left as incertae sedis. This division into species-groups will help in the reliable identification of species and will aid in the completion of the revision of subgenus. This report is the first part of the taxonomic revision of the subgenus Deltohyboma; it is based on the examination of all type specimens and almost 9,800 specimens of which approximately 1,200, mostly males, had their genitalia studied. The 19 species-groups recognized here are based mainly on characters described for the first time for Deltohyboma, namely, the state of a) the anterior margin of the clypeus (between the clypeal teeth), b) the internal margin of hypomera, c) the ventral face of the protibia, d) the posterior margin of the metafemur, and e) several new characters resulting from the first detailed study of the aedeagus and the endophallus of the group. Diagnosis, description, geographic distribution, composition and identifications keys (for males as well as males and females) for the species-groups are provided.
