- ItemAcesso aberto (Open Access)Checklist dos percevejos-do-mato (Hemiptera: Heteroptera: Pentatomoidea) do Estado de São Paulo, Brasil(Instituto Virtual da Biodiversidade | BIOTA - FAPESP, 2011-12-01) Grazia, Jocélia; Schwertner, Cristiano Feldens [UNIFESP]; Universidade Federal do Rio Grande do Sul Instituto de Biociências Programa de Pós-graduação em Biologia Animal; Universidade Federal de São Paulo (UNIFESP)Pentatomoidea knowledge in São Paulo state is here updated. Two hundred and two species in 92 genera belonging to Acanthosomatidae, Canopidae, Cydnidae, Pentatomidae, Phloeidae, Scutelleridae, Tessaratomidae and Thyreocoridae are registered. Forty one species were added and 13 taxonomical and nomenclatorial corrections were made comparing with the data presented in the first edition of the Biota SP in 1999. Pentatomoidea species richness of São Paulo state is around 25% of the species known to Brazil and around 3% of the world fauna. The increase of the studies in scarcely known families in Brazil will certainly raise these numbers. Pentatomidae was the most numerous taxon in São Paulo state, with 80% of the registered species.
- ItemAcesso aberto (Open Access)Comparative morphology of immature stages of four species of Chinavia (Hemiptera, Pentatomidae), with a key to the species of Rio Grande do Sul, Brazil(Pensoft Publ, 2013-01-01) Fuerstenau, Brenda Bianca Rodrigues Jesse; Schwertner, Cristiano Feldens [UNIFESP]; Grazia, Jocelia; Univ Fed Rio Grande do Sul; Universidade Federal de São Paulo (UNIFESP)Chinavia Orian (1965) is one of the most diverse genera of Pentatomidae, distributed in the Afrotropical, Neotropical and Nearctic Regions. Thirty-two species are recorded for Brazil, some of them having potential economic impact because they are found on crops and referred to as pests. the morphology of the five nymphal instars of C. armigera (Stal, 1859), C. aseada (Rolston, 1983), C. brasicola (Rolston, 1983) and C. runaspis (Dallas, 1851) are described here. Through a comparative study, identification keys were developed to allow an early identification of the 12 Chinavia species of Rio Grande do Sul.
- ItemSomente MetadadadosPentatomidade (Hemiptera: Heteroptera) of the Pampa biome: Serra do Sudeste and Parque de Espinilho da Barra do Quarai, Rio Grande do Sul, Brazil(Revista Biota Neotropica, 2010-07-01) Bunde, Paulo Roberto Sousa; Grazia, Jocelia; Mendonca Junior, Milton de Souza; Schwertner, Cristiano Feldens [UNIFESP]; Silva, Eduardo Jose Ely e; Garcia, Elen Nunes; Univ Fed Rio Grande Sul UFRGS; Universidade Federal de São Paulo (UNIFESP); Universidade Federal de Pernambuco (UFPE)A list of the Pentatomidae species of the Pampa biome, State of Rio Grande do Sul, Brazil is provided. the list is based on surveys carried out in the Serra do Sudeste, Cangucu and Cacapava counties, and in Parque de Espinilho da Barra do Quarai during 2003-2004; these areas were never collected in Rio Grande do Sul state before. Sweeping net and beating tray were used to sample herb layer, and trees and shrubs, respectively. Fifty one species of Pentatomidae were registered, distributed in five subfamilies (Asopinae, Cyrtocorinae, Discocephalinae, Edessinae and Pentatominae) and 27 genera. the Pentatominae subfamily had the largest number of species (32 spp.). All the registered localities represent new records to the local fauna, and host plants were identified for nine pentatomid species.
- ItemSomente MetadadadosREVIEW OF THE NEOTROPICAL GENUS ALEIXUS MCDONALD (HEMIPTERA: HETEROPTERA: PENTATOMIDAE: PROCLETICINI), WITH DESCRIPTION OF A NEW SPECIES AND CLADISTIC ANALYSIS OF THE TRIBE PROCLETICINI(New York Entomological Soc Inc, 2012-01-01) Schwertner, Cristiano Feldens [UNIFESP]; Grazia, Jocelia; Universidade Federal de São Paulo (UNIFESP); Univ Fed Rio Grande do SulThe genus Aleixus McDonald is reviewed and a new species described. The genus was monotypic and known from a single female from Brazilian Amazonia. The new species Aleixus tobyschuhi described from southern Brazil, greatly extends the distribution of Aleixus. A cladistic analysis, including 30 morphological characters and 18 taxa, was performed using TNT with the implicit enumeration algorithm, with three weighting schemes: equal (EW), successive approximation (SW), and implied weighting (IW). Analysis under EW resulted in four cladograms (L = 74, CI = 60, RI = 78). Analyses under SW and IW resulted in one most parsimonious cladogram, with fit varying from 20.4 (K = 0.64) to 26.6 (K = 5.80). The cladogram obtained under differential weighting schemes is included in the set of cladograms found under EW. The monophyly of the tribe Procleticini and genus Aleixus were recovered in all analyses.. Non-ambiguous synapomorphies for Aleixus include antennal segment II longer than antennal segment I, and humeral angles developed in spatular projections, dorsally bifid. Non-ambiguous synapomorphies of Procleticini are metasternum sulcate, ventral rim of pygophore with a medial U-shaped emargination and with 1 + 1 process with different degree of development, and gonocoxites 8 smaller than laterotergites 9. A hypothesis of relationships among Procleticini genera was possible only under IW analysis. Two main clades were recognized: clade A, including the genera Brepholoxa Van Duzee, Dendrocoris Bergroth, Procleticus Berg, and Thoreyella Spinola; and clade B, including the genera Aleixus, Odmalea Bergroth, Parodinalea Rider, and Pseudobebaeus Distant.
