    Os insetos da família Scarabaeidae sao detritívoros e sua eficiencia na remoção de matéria orgánica em decomposição tem grande influencia na manutenção dos ecossistemas terrestres (Halffter and amp; Matthews 1966, Hanski and amp; Cambefort 1991). A maioria das espécies da família tem hábitos coprófagos, alimentandose principalmente de excrementos de mamíferos

    Presented is a multilingual (English, Portuguese, Spanish, Dutch and French) key to the 119 currently recognized genera and subgenera of scarabaeine dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) occurring in the New World. Also included are illustrations of representative species of all taxa included in the key as well as supplementary references to studies at the species level.Fil: Vaz de Mello, Fernando Z..

    The Taxonomic Revolution of New World dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae)

    Get PDF
    After almost two decades of stagnation, the taxonomy of the New World Scarabaeinae dung beetles has since 1988 been going through a period of great effervescence. In the last 35 years, 81 complete revisions and 69 supplements have been produced by 86 authors based in 15 countries, addressing the taxonomic status of 950 species. This is what we christen as the Taxonomic Revolution of New World dung beetles. We review the history and products of this revolution, explore its causes and its apparent exceptionalism among most other New World Coleoptera groups, and point to the many great challenges that still face the scarabaeine taxonomists. An aspect of interest to ecologists is the coevolution of the Taxonomic Revolution with what we call the Ecological Revolution of dung beetles, i.e., the similar expansion in ecological studies about these organisms. We argue that it has been the continuous feedback between these two simultaneous processes that has enabled each of them to exist and flourish: without the Ecological Revolution, the Taxonomic Revolution could not have existed, and vice-versa. Ecologists and taxonomists are partners in the scientific enterprise, symbionts one may say

    A new species of the genus Canthon Hoffmannsegg (Coleoptera, Scarabaeidae, Scarabaeinae, Deltochilini) from central Brazil

    A new species of Canthon is described, illustrated and the morphological similarities with related species are discussed. The species Canthon cleidecostae was named after Dr. Cleide Costa a great beetles specialist. The subgeneric category of species is considered incertae sedis until the taxonomic revision of the genus Canthon is fully addressed. Also, we provide a key for genera, subgenera and isolated species-groups that can be confused with the genus Canthon

    Checklist with a key to genera and subgenera of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) present and supposed for Ecuador.

    The beetles of the Subfamily Scarabaeinae are a group that have been used in taxonomic, ecological, natural history, biodiversity and conservation studies recently, as they are good indicators of habitat quality and due to their great genera and species richness. Their taxonomy is relatively well known, however new taxa and nomenclatural changes are frequently ocurring, mainly due to taxonomic revisions at the genus level. Currently in the Neotropics, 127 taxa (between genera and subgenera) are recorded, with 59 taxa belonging to 33 genera and 220 species (with 23 new records) present in Ecuador, and nine more genera that allegedly could be registered. With the aim of promoting the study and knowledge of this group in Ecuador, an identification key for the genera and subgenera present and/or supposed to be present in this country is provided in this work, which includes current taxa with Scarabaeinae (Coleoptera: Scarabaeidae) for the neotropic

    A new species of Isocopris Pereira and Martínez, 1960 (Coleoptera: Scarabaeidae: Scarabaeinae) from the Southwest Brazilian Amazon

    Get PDF
    A new species from the southwest Brazilian Amazon, Isocopris rossinii Arias-Buriticá, Bach, and Vaz-de-Mello, new species, is described along with a diagnosis, illustrations, and discussion of its taxonomic position in the genus. This new species is readily distinguished by a deep depression in the frons, a large and trapezoidal ventral clypeal process in lateral view, a glabrous metaventral anterior lobe, the morphology of the aedeagus with triangular and symmetrical parameres, the presence of a subgenital plate, and large and asymmetrical lamellae copulatrix. Females show secondary sexual dimorphism, with the elytral striae widened from the first to the fourth in the central area. Here we present an updated key for the species of the genus Isocopris Pereira and Martínez, 1960
