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

Abstract: 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 o… Show more

“…In contrast, the identification was incorrect for some species with restricted distributions in Colombia such as Canthon arcabuquensis , Dichotomius andresi , Uroxys cuprescens , and Deltochilum susanae , the latest was first identified as the morphospecies Deltochilum sp. 12H [ 42 ] and later described as a new species [ 43 ] or species with Andean distributions as in Dichotomius protectus , Eurysternus marmoreus and Ontherus brevicollis [ 44 49 ]. In the case of Scarabaeinae dung beetles, the barcode results helped to confirm at least five species that were assigned as morphospecies in the dung beetles of Colombia “Reference Collection” hosted at of IAVH Entomological Collection.…”

“…The dung beetles (Scarabaeinae) of the genus Deltochilum Eschscholtz, 1822 are widely distributed in the Neotropical region, comprising 114 valid species (including four new species described here). Deltochilum is divided into eight subgenera (Génier 2012;González-Alvarado et al 2019;González-Alvarado & Vaz-de-Mello 2014, 2021Silva et al 2015). Within those subgenera, two are monospecific Euhyboma Kolbe, 1893 andRubrohyboma Paulian, 1938; one has two species Parahyboma Paulian, 1938; three have been taxonomically revised Aganhyboma Kolbe, 1893, Deltochilum s. str.…”
