Avian predators may represent an important selective pressure favouring the evolution of aposematic colouration in millipedes that present chemical defences. However, the role of their warning colouration in predator avoidance remains poorly explored under field conditions, especially in Neotropical forests. Thus, to evaluate the hypothesis of the...

Glomeridesmus spelaeus n. sp., the first Glomeridesmida described from Brazil and only the second known troglobiont of the order, is described from iron caves of the Amazonian.

The new species is unique among millipedes of the order Polydesmida in having 39+t rings in adult males, two rather than four spinnerets, and in its highly plesiomorphic gonopods, which resemble those of basal members of the orders Callipodida an...

Despite their large size and intimidating appearance, most mygalomorph spiders do not cause severe envenomation in Brazil. “Programa Estadual de Vigilância de Acidentes por Animais Peçonhentos da Secretaria de Estado da Saúde do Paraná”, through the “Sistema de Notificação de Animais Peçonhentos” (SINAP), documents the occurrence of synanthropic sp...

Pseudonannolene Silvestri, 1895 (Spirostreptida, Pseudonannolenidae) is one of the most common genera of millipedes in Brazilian caves. To date, only three troglobitic species are known in a list of 56 species described for the genus. In this study, we report new records of the cave-dwelling species Pseudonannolene ambuatinga Iniesta & Ferreira, 20...

Reports of mites parasitizing arthropods are common worldwide. However, there hasn't been a single record of mite parasitism by any Erythraeidae species on the millipede Polyxenidae in Brazil. To address this gap, we present a record of the species Charletonia rocciai Treat & Flechtmann, 1979 (Trombidiformes: Erythraeidae), parasitizing a specimen...

No município de Codó, no estado do...

The intriguing thanatosis was observed for the second time for a member of the family Chelodesmidae. This behavior was recorded for the species Pseudoleptodesmus rubescens (Gervais, 1836), in the municipality of Magé, state of Rio de Janeiro, Brazil.

Somatic characters are shared by many Chelodesmidae groups, and generic placement and species identifications traditionally have been based on gonopodal morphology. Female genitalic characters have been largely neglected and are rarely photographed or illustrated. This is rather unfortunate as the morphology of female genitalia presents important c...

Here we describe the new species Pseudoporatia kananciue Iniesta, Bouzan, Souza & Brescovit, n. sp., widespread in the Amazonian ferruginous landscape of the state of Pará, Brazil.

Millipedes are well-known for their limited dispersal abilities with species restricted to mountains, islands, and patches of forest being important models for formulating and testing biogeographic hypotheses. The order Spirostreptida is composed of nearly 1300 species distributed across the Afrotropical, Oriental, and Neotropical regions. The orde...

Millipedes are known by their importance in ecological systems, although some species are regarded as agricultural pests in some poly- or monocultures. Canola (Brassicaceae: Brassica spp.) is an important feedstock for biodiesel production and a potential ingredient in the food industry, but with several arthropod pests causing damage to its cultiv...

A total of 25 species and subspecies from 20 genera and...

Phylogenetic relationships of the suborder Cambalidea have been a well-known focus of discussion over the past 100 years. The most recent approach to the suborder is based on the morphology of the sexual structure of males and of the gnathochilarium. The phylogenetic interpretation of the gnathochilarium has been especially criticized due to the po...

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 maxim...

Physical features and lithology variations contribute to promoting changes in faunal composition and richness between caves in Neotropics. Cave lithology effects on biodiversity were reported to iron ore caves in Brazil, however, it is less clear to granitoid and quartzite caves. Hence, based on these two kinds of rocks we correlate invertebrates s...
