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.

Xenicola brauni sp. n., a new katydid species (Orthoptera: Tettigoniidae:Phaneropterinae) from the Atlantic Forest, southeastern Brazil.

A new species of Xenicola Uvarov, 1940 (Orthoptera: Tettigoniidae: Phaneropterinae), X. brauni sp. n.

Contributions to the knowledge of Canuleius Stål (Phasmatodea: Heteronemiidae): taxonomy, morphology and notes on the biology of two species.

We present new information on the poorly known genus of stick insects, Canuleius Stål, 1875, with redescriptions of two Brazilian species, Canuleius grandis Toledo Piza, 1936 and Canuleius sanguinolentus (Brunner von Wattenwyl, 1907) comb. nov., the latter herein transferred from Bacteria Berthold, 1827.
