1. The Evolution of Pneumatic Foramina in Pterosaur Vertebrae
Abstract: Pterosaurs possess skeletal pneumatization, which can be assessed externally through the observation of pneumatic foramina. These foramina vary in position, shape, and number among taxa. Here we propose new characters referring to the position and number of pneumatic foramina present in cervical and dorsal vertebrae of pterosaurs. A cladistic analy

2. A phylogenetic investigation of the Neotropical genus Alphamenes van der Vecht, 1977 (Hymenoptera, Vespidae, Eumeninae)
ABSTRACT Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systemati

3. Taxonomic revision of the Neotropical Lauxaniidae genus Neopachycerina Malloch, 1933 (Diptera: Schizophora), with description of a new species
Abstract A systematic review of the Neotropical Lauxaniidae genus Neopachycerina Malloch, 1933 is presented. The genus is characterized mainly based on some features of the head, like the anterior pair of fronto-orbital setae conspicuously shorter than posterior one and rather close to them; face with a distinct elevation between antennal bases; antenna slig

4. Areas of endemism of hummingbirds (Aves: Apodiformes: Trochilidae) in the Andean and Neotropical regions
ABSTRACT Using track analysis and cladistic biogeography, we identified areas of endemism of hummingbirds in the Andean and Neotropical regions. Our results point out that the current areas of endemism of hummingbirds occur in the Andes, Guiana Shield, the Lesser Antilles, western Central and North America and the Chiapas Highlands. The cladistic biogeograph

5. Phylogeny of the Neotropical longhorn beetle genus Ateralphus (Coleoptera: Cerambycidae: Lamiinae)
ABSTRACT Ateralphus Restello, Iannuzzi & Marinoni, 2001 is a Neotropical genus of longhorn beetles composed of nine species. This genus was proposed from splitting Alphus White, 1855 into other two genera: Ateralphus and Exalphus Restello, Iannuzzi & Marinoni, 2001. Even though Ateralphus (nine species), Alphus (four) and Exalphus (18) were recently revised,

6. Cladistic analysis of the Argentinian species of the genus Bostryx (Gastropoda, Stylommatophora) based on morphological evidence
ABSTRACT The genus Bostryx Troschel, 1847 is found exclusively in South America, from Ecuador to Chile and mainly in the Andes mountain range. The phylogeny of Argentinian species of Bostryx was based on morphological characters of 19 species from Argentina, 5 from Peru and 7 from Bostryx-related genera, belonging to Bulimulidae and Odontostomidae.

7. Relationships of †Codoichthys carnavalii Santos, 1994 (Teleostei, Clupeomorpha, †Ellimmichthyiformes) from the Late Aptian of São Luís-Grajaú Basin, NE Brazil
ABSTRACT †Codoichthys carnavalii is a clupeomorph fish only found in calcareous concretions of Codó Formation, State of Maranhão. It is known based on three specimens housed in the paleontological collection of the Museu de Ciências da Terra of Departamento Nacional da Produção Mineral, Rio de Janeiro. It was omitted in most of recent cladistic analys

8. Genetic analysis reveals candidate species in the Scinax catharinae clade (Amphibia: Anura) from Central Brazil
Abstract Scinax (Anura: Hylidae) is a species-rich genus of amphibians (113 spp.), divided into five species groups by morphological features. Cladistic analyses however revealed only two monophyletic clades in these groups: Scinax catharinae and Scinax ruber. Most species from the S. catharinae clade are found in Atlantic rainforest, except for Scinax canas

9. Vriesea (Bromeliaceae, Tillandsioideae): a cladistic analysis of eastern Brazilian species based on morphological characters
Abstract Vriesea, with about 280 species distributed in two sections, Vriesea and Xiphion, is recognized as polyphyletic. We provide the cladistic analysis based on morphological data, with emphasis on species from eastern Brazil, its main center of diversity, which emerged as a monophyletic group in previous molecular and combined analysis.

12. Description and phylogenetic position of a new species of Metarthrodes (Opiliones: Gonyleptidae: Caelopyginae) from Bahia, northeastern Brazil
We describe Metarthrodes oxum sp. nov. from Camacan, state of Bahia, Brazil, the second species of Caelopyginae described from the state, after Metarthrodes xango Pinto-da-Rocha, 2002. Metarthrodes oxum sp. nov. can be recognized by the presence of a pair of white spots on area I, white C-shaped stripes on lateral grooves of area III, posterior margin with t
