On the Brazilian Exocnophila stick insects (Insecta: Phasmatodea), with the description of a new species.

Several stick insects occurring in Brazil belong to the Diapheromerinae. Before this work, the Brazilian genus Exocnophila contained three species known only from females, Exocnophila exintegra Zompro, 2001, Exocnophila tuberculata (Brunner von Wattenwyl, 1907) and Exocnophila cornuta (Brunner von Wattenwyl, 1907). Based on recently collected material, we found that the males of Exocnophila are assigned to another genus in the Diapheromerinae, the heterogeneous Bacteria.

Taxonomic Revision, Morphology and Natural History of the Stick Insect Genus Serville, 1831 (Insecta: Phasmatodea).

Stick insects (Phasmatodea) are quite diverse in the Neotropical region. Among them, Serville belongs to Pseudophasmatidae and comprises winged, roughly brownish phasmids that resemble bark or dry branches and inhabit the Atlantic Forest in Brazil. In this study, we present a redescription and revision of the genus that include three valid species, , , and sp.

Revision of the Neotropical stick insect genus Ocnophila (Phasmatodea: Diapheromeridae) with a new species from Colombia.

The genus Ocnophila Brunner, 1907 is here redescribed with an emended diagnosis, containing three valid species from Venezuela and Colombia: Ocnophila integra Brunner, 1907 with Ocnophila signatior Brunner, 1907 syn. nov. as a new junior synonym, Ocnophila iphicla (Westwood, 1859) and Ocnophila serrata sp.

Contributions to the knowledge of Ceroys (Miroceroys) Piza, 1936 (Phasmatodea: Heteronemiidae): two new mossy stick insects from the Atlantic Forest of Brazil.

Several lineages of stick insects (Phasmatodea) are poorly studied, especially in the Neotropics. Recently, Brazilian stick insects have been subject of significant research and, among them, the Heteronemiidae, although several genera remain to be explored. Pygirhynchini is an Heteronemiidae lineage currently containing four genera, of which three occur in Brazil: Ceroys, Canuleius and Pygirhynchus.

Flying or digging? The trapdoor spider genus Neocteniza Pocock, 1895: Redescription of three species, new records from Brazil, notes on natural history and first record of ballooning for Idiopidae (Araneae, Mygalomorphae).

The Neotropical trapdoor spider genus Neocteniza Pocock, 1895 is distributed throughout Central and South America. The genus currently comprises 18 species and little is known about the biology of these spiders. We provide an amended diagnosis for the genus Neocteniza and the species: N.
