The objective of this work was to elaborate supporting tools for the correct identification of Scarabaeidae, by an identification key of genera, and a commented list of the species present in Brazilian pastures. A data survey was performed on the specimens deposited in the main Brazilian collection and reported on the recent scientific literature. The distribution of the species was identified in the Brazilian states, based on information on feeding preference, ecological aspects, and potential for faeces removal action. The species were classified according to their importance for pastures, as: high, medium, and low. A key for the identification of the genera and subgenera of Scarabeidae present in the pastures was constructed through the analysis of the external morphology of the species and, when needed, by the analysis of sexual traits. Twenty genera and 76 species of scarab beetles were recorded for Brazilian pasturelands, among which Dichotomius bos, Dichotomius nisus, Trichillum externepunctatum, Ontherus appendiculatus, Onthophagus aff. hirculus, and Digitonthophagus sp. were considered as the most frequent, widely distributed, abundant, and important. The dichotomous key will contribute to the identification of the genera and subgenera of dung beetles (Scarabaeidae: Scarabaeinae) occurring in the Brazilian pastures. |

The occurrence of lamellae in soils and sediments has direct implications for agricultural production, and for stratigraphic and geomorphological studies. Although lamellae have been studied for more than a century, their origin remains controversial. The aim of this study was to identify the origin and formation mechanisms of lamellae in autochthonous soils developed from metamorphic rocks in a semi-arid area of Northeast Brazil. As such, the spatial organization of soil profiles was evaluated in a topolithosequence, through structural analysis of the pedological coverage for subsequent soil sampling. Morphological, chemical, physical, sedimentological, mineralogical, and micromorphological analyses were carried out on the studied slope and in greater detail in four soil profiles. The results indicated that clay particles predominantly smaller than 0.2 µm are eluviated in a sandy soil matrix, infilling voids and coating quartz grains, which are organized in layers of densely packed fine sand, impeding clay translocation and helping form lamellae. Although the micromorphological properties of the lamellae demonstrate their pedogenic origin, the contribution of strips of polycrystalline quartz constitutes a petrogenic component of the illuviation process. Therefore, the genesis of the lamellae is better described based on a petro-pedogenic origin. We suggest a restructuring of the concept of petro-pedogenic origins, including the structural influence of metamorphic rocks, as illuviated clay deposition occurs in accordance with a physical barrier provoked by the increase and organization of fine sand particles, distributed horizontally and in parallel, arising from the disintegration of polycrystalline quartz grains, which indicates geological control in the genesis of lamellae, corresponding to petrogenic evidence. Furthermore, the morphological distinction of the lamellae seems to be more associated with the fine sand content (<0.25 mm), and its packing with larger grains of quartz in the soils.
