Butterflies (Lepidoptera: Papilionoidea and Hesperioidea) from two forest fragments in northern Rio Grande do Sul, Brazil
A systematic survey was carried out in the city of Frederico Westphalen from November 2006 to June 2007, in two sampling localities, in which 1.785 samples were recorded, distributed in 161 species.
Male Genitalia of Neotropical Charaxinae: A Comparative Analysis of Character Variation
Substantial variation was found in the genital structures of Anaeini, making it difficult to establish structural patterns for this group, but structural variation may be very efficient to diagnose species, such as some species of Memphis Hübner and Fountainea Rydon, which can be easily identified through the presence of spines on the valva.
Structures related to pheromone storage in alar androconia and the female abdominal scent gland of Heliconius erato phyllis, Heliconius ethilla narcaea, and Heliconius besckei (Lepidoptera:…

The findings revealed different sizes of external androconial scales and an internal group of porous structural vesicles that are probably related to the preservation of internal space, reception and storage of secretions, and elimination of volatiles when the male is actively involved in courtship.

Broadening the taxonomic representation by including specimens from distant geographic locations, and including greater phenotypic diversity, allowed us to uncover unappreciated taxonomic diversity and provide a firmer basis for exploring the evolution of this group of spectacular butterflies.
Exoskeleton Morphology of Three Species of Preponini, with Discussion of Morphological Similarities among Neotropical Charaxinae (Lepidoptera: Nymphalidae)—I. Head, Cephalic Appendages, and Cervix
The morphology of the head, appendages, and cervical region of three species of the butterflies are compared through descriptions, illustrations, and scanning electron micrographs, showing unique characteristics for each species and/or genus, or characteristics shared among the species analyzed.
Exoskeleton Morphology of Three Species of Preponini, with Discussion of Morphological Similarities among Neotropical Charaxinae (Lepidoptera: Nymphalidae)—II. Thorax and Thoracic Appendages
The results are compared with three other species, Prepona claudina annetta (Gray, 1832), Memphis moruus stheno Hübner,  and Zaretis itys itylus (Westwood, 1850), revealing previously unrecognized similarities among species of Charaxinae.
Exoskeleton Morphology of Three Species of Preponini, with Discussion of Morphological Similarities among Neotropical Charaxinae (Lepidoptera: Nymphalidae)—III. Abdomen and Genitalia
The abdomen is commonly the most informative tagma for butterflies and in Charaxinae, this tagma supports diagnoses of both genera and species, besides providing a solid morphological base for recent molecular findings for Preponini.
