Atahualpacoris henryi, a new species of plant bug from Colombia (Heteroptera, Miridae, Mirini)
(ZooKeys, 2018) Ferreira, Paulo Sérgio Fiuza; Lopes, Jose Luis Benavides; Souza, Fagner de; Ferreira, Luciano Santana Fiuza
A new species of plant bug in the genus Atahualpacoris Carvalho, tribe Mirini, is described. Morphological characters differentiating Atahualpacoris from the related genus Calocorisca are provided, and a diagnosis of each known species of Atahualpacoris is presented. Specimens of the new species were collected by light trap in a natural ecosystem of the Andes Mountains, Department of Tolima, Colombia. The adult and male genitalia are illustrated.
Diversity of Hemiptera (Arthropoda: Insecta) and their natural enemies on Caryocar brasiliense (Malpighiales: Caryocaraceae) trees in the Brazilian Cerrado
(Florida Entomologist, 2016) Leite, Germano Leão Demolin; Veloso, Ronnie Von dos Santos; Zanuncio, José Cola; Alonso, Jatnel; Ferreira, Paulo Sérgio Fiuza; Almeida, Chrystian Iezid Maia; Fernandes, Geraldo Wilson; Serrão, José Eduardo
The Cerrado occupies about 23% of the Brazilian territory and is characterized by great diversity of plants and insects and a great degree of endemism, and Caryocar brasiliense A. St.-Hil. (Malpighiales: Caryocaraceae) is widely distributed in this region. The diversity and abundance of hemipterans and their natural enemies were studied on trees of C. brasiliense in the Cerrado, pasture, and anthropic area in Montes Claros, Minas Gerais State, Brazil. We observed 1 rare, 8 common, and 1 frequent species of sucking insects; and 2 rare, 7 common, and 6 frequent species of natural enemies. Sucking insects and their natural enemies were most abundant in the pasture and least abundant in the Cerrado. Increasing diversity indices and numbers of species and individuals of sucking insects were followed by similar trends in the populations of natural enemies. Increasing populations of sucking insects led to greater numbers of individuals of ants, green lacewings, predator thrips, and ladybeetles. Aluminum level positively affected the number of species and individuals, and the pH of the soil reduced those of sucking insects. Leafhoppers had greater numbers on plants on soils with low pH values and high aluminum levels, but the opposite was noted for the aphids.

Os autores apresentam uma chave taxonômica para a identificação dos gêneros da subfamília Bryocorinae (Heteroptera, Miridae), abrangendo a região neotropical até o norte do México. Três tribos são consideradas nesta distribuição geográfica. Este trabalho inclui 24 novos gêneros descritos após a publicação de Carvalho (I) referente às chaves para os gêneros de Miridae do mundo.

New findings of Anastrepha (Diptera: Tephritidae) in the state of Espírito Santo, Brazil
(Florida Entomologist, 2012-09) Martins, David Dos Santos; Fornazier, Maurício José; Uramoto, Keiko; Ventura, José Aires; Ferreira, Paulo Sérgio Fiuza; Zanuncio, José Cola
Anastrepha Schiner is the genus of Tephritidae with the greatest diversity in the Neotropical region and the largest number of species in Brazil, and which imposes quarantine restrictions for imports of fruits and vegetables from countries in which it occurs. The objective of this paper is to present new records of Anastrepha species in State of Espírito Santo, Brazil. McPhail traps were used to capture adults in 74 municipalities. The occurrence of A. daciformis Bezzi, A. dissimilis Stone, A. mixta Zucchi and A. parallela (Wied.) are new records for the State of Espírito Santo.
Seasonal abundance and sexual variation in morphometric traits of Oxelytrum discicolle (Brulle, 1840) (Coleoptera: Silphidae) in a Brazilian Atlantic Forest
(Biota Neotropica, 2006) Ferreira, Paulo Sérgio Fiuza; Pires, Evaldo Martins; Guedes, Raul Narciso Carvalho; Mendes, Márcio; Coelho, Lívia Aguiar
A total of 293 specimens of Oxelytrum discicolle were sampled weekly over a period of two years using a black light trap. The study took place in an Atlantic Forest reserve located near Viçosa city, Minas Gerais State, Brazil. The period of peak abundance of O. discicolle occurred during the wet season between the months of October and March. Statistical analysis showed that the abundance of individuals was significantly and positively correlated with temperature, but not with rainfall or relative humidity. Of 28 morphological measurements taken on each collected specimen, seven were found to be sexually dimorphic; however, neither morphology nor the degree of sexual dimorphism varied significantly among seasons.
Seasonal and interpopulational morphometry variation of Platyscytus decempunctatus (Carvalho 1945) (Heteroptera: Miridae)
(Biota Neotropica, 2008-04) Pires, Evaldo Martins; Guedes, Raul Narciso Carvalho; Serrão, José Eduardo; Ferreira, Paulo Sérgio Fiuza
A morphometry study was carried out with Platyscytus decempunctatus (Carvalho 1945) collected during the dry and wet seasons in Viçosa county, state of Minas Gerais, Brazil and in other 23 counties from the states of Minas Gerais and Rio de Janeiro in Brazil. A total of 30 males and 30 females were collected in Viçosa at each season and additional insects (20 males and 20 females) were collected at each county surveyed. The analysis with 27 morphological traits was carried out to verify the seasonal influence, differences between sexes and among populations in specimens from Viçosa. The females of P. decempunctatus collected in Viçosa were larger than the males in most of the traits evaluated in both seasons (dry and wet). The males showed only two body traits larger than the females. Interpopulational morphometry differences of P. decempunctatus were significantly correlated with geographic distance among sampling sites.
