Aim: The knowledge of biodiversity facets such as species composition, distribution and ecological niche is fundamental for the construction of biogeographic hypotheses and conservation strategies. However, the knowledge on these facets is affected by major shortfalls, which are even more pronounced in the tropics. This study aims to evaluate the effect of sampling bias and variation in collection effort on Linnean, Wallacean and Hutchinsonian shortfalls and diversity measures as species richness, endemism and beta-diversity.
Location: Brazil.
Methods: We have built a database with over 1.5 million records of arthropods, vertebrates and angiosperms of Brazil, based on specimens deposited in scientific collections and on the taxonomic literature. We used null models to test the collection bias regarding the proximity to access routes. We also tested the influence of sampling effort on diversity measures by regression models. To investigate the Wallacean shortfall, we modelled the geographic distribution of over 4000 species and compared their observed distribution with models. To quantify the Hutchinsonian shortfall, we used environmental Euclidean distance of the records to identify regions with poorly sampled environmental conditions. To estimate the Linnean shortfall, we measured the similarity of species composition between regions close to and far from access routes.
Results: We demonstrated that despite the differences in sampling effort, the strong collection bias affects all taxonomic groups equally, generating a pattern of spatially biased sampling effort. This collection pattern contributes greatly to the biodiversity knowledge shortfalls, which directly affects the knowledge on the distribution patterns of diversity.
Main conclusions: The knowledge on species richness, species composition and endemism in the Brazilian biodiversity is strongly biased spatially. Despite differences in sampling effort for each taxonomic group, roadside bias affected them equally. Species composition similarity decreased with the distance from access routes, suggesting collection surveys at sites far from roads could increase the probability of sampling new geographic records or new species.

Hoffmanopeltis gen. nov. (type species Leptodesmus ravus Schubart, 1956) is described to accommodate H. ravus (Schubart, 1956) comb. nov. and H. contiger sp. nov, from Cerrado-Atlantic Forest ecotone, southeastern Brazil. The new genus is compared with other genera of Chelodesmidae, in particular AtlantodesmusHoffman, 2000 and Plectrogonodesmus Hoffman, 2012, based on the morphology of the acropodital region and solenomere. In addition, an updated list of species of Chelodesmidae recorded in the state of Minas Gerais, Brazil, is provided.

The genus Holopodostreptus Carl, 1913 is a poorly known monotypic genus endemic to Ecuador. It differs from most other Pseudonannolenidae by a set of characteristics of the gnathochilarium and gonopods. Herein, we provide descriptive notes of males of H. braueri Carl, 1913 based on recently collected material. Females of the species are described for the first time, and images of the vulvae are provided. In addition, we attempt for the first time to place Holopodostreptus in a phylogenetic context. With a total of 14 taxa and 41 morphological characters, and under implied weighting (k = 6), a single most-parsimonious tree is recovered (total fit = 35.86). The genus is recovered as sister-group of Physiostreptus Silvestri, 1903. The clade Holopodostreptus + Physiostreptus is supported by one synapomorphy (absence of setae on the prefemoral process of leg-pair 1 in males) and one homoplastic transformation (narrow telopodite). Based on the phylogenetic results, notes on the subfamilies Pseudonannoleninae, Cambalomminae and Physiostreptinae and a key for all pseudonannolenid genera are provided.

Summary: The millipede Oxidus gracilis (C. L. Koch, 1847) is a cosmopolitan introduced species largely recorded in the southeast region of Brazil. The species is considered an agricultural pest with records in poly- or monocultures, and its influence on native communities of plants and invertebrates is still unknown in Brazil. From this perspective, a maximum entropy model was used to explore the predicted distribution of O. gracilis in Brazil. The results showed a highly suitable area in Atlantic Forest (AUC = 0.949 ± 0.02). Considering percent contribution, annual mean temperature (= 54.9) was the main variable which has influenced the modeling. The potentially suitable areas recovered in Atlantic Forest suggest that attention should be given to its possible invasion and the potential damage of O. gracilis to natural communities.

Modélisation de la niche écologique prédisant l’invasion potentielle du mille-pattes non indigène Oxidus gracilis (C. L. Koch, 1847) (Polydesmida : Paradoxosomatidae) dans la forêt atlantique brésilienne

Résumé: Le mille-pattes Oxidus gracilis (C. L. Koch, 1847) est une espèce introduite cosmopolite et largement observée dans la région sud-est du Brésil. L’espèce est considérée comme un ravageur agricole des mono- et polycultures, et son influence sur les communautés indigènes de plantes et d’invertébrés est encore inconnue au Brésil. Dans cette perspective, un modèle d’entropie maximale a été utilisé pour explorer la distribution potentielle d’O. gracilis au Brésil. Les résultats ont montré une zone favorable élevée dans la forêt atlantique (AUC = 0.949 ± 0.02). La température moyenne annuelle (= 54.9) a été la principale variable qui a influencé la modélisation. Les zones potentiellement favorables de la forêt atlantique suggèrent qu’il faut être vigilant quant à sa possible invasion et aux dommages potentiels sur les communautés indigènes.
