Illustrated key for identification of the species included in the genus Leptoglossus (Hemiptera: Heteroptera: Coreidae: Coreinae: Anisoscelini), and descriptions of five new species and new synonyms

Five new species of Leptoglossus are described: L.caicosensis from Turks and Caicos Island, L. egeri and L. impensus from Bolivia, L. franckei from Costa Rica, and L. polychromus from Ecuador, Cooperative Republic of Guiana (British Guiana), and French Guiana. Leptoglossus argentinus Bergroth is synonymized under L. chilensis chilensis (Spinola) and Narnia anaticula Brailovsky & Barrera under Leptoglossus occidentalis Heidemann. Dorsal view drawings and key to the 61 known species and 1 subspecies are included; a complete checklist, and the position of each species within the species-group defined herein, are given except for two species L. macrophylus Stål and L. polychromus sp.nov., that are insertae-sedis. The pronotal disk, hind legs, and male genital capsule of the new species here described are illustrated.

SIX NEW SPECIES OF LEPTOGLOSSUS GUERIN (HEMIPTERA: HETEROPTERA: COREIDAE: COREINAE: ANISOSCELINI)

Abstract Six new species of Leptoglossus Guérin from Brazil, Costa Rica, México, Peru, and Venezuela are described. Diagnostic taxonomic characters of antennal segments, legs, male genital capsules, and dorsal views of some species are illustrated. Most of the species are placed in their corresponding species-group, as well as the previous incertae-sedis species.

First record of Hesperolabops nigriceps Reuter (Hemiptera: Miridae) on Opuntia ficus-indica in Milpa Alta, Mexico City

In recent years a species of Hesperolabops has become a problem as a pest of nopalitos, Opuntia ficus-indica, in Milpa Alta, in the south of Mexico City, which is the most important production region of this vegetable in the country. A survey of Hesperolabops in Milpa Alta has resulted in the first report of Hesperolabops nigriceps Reuter. This occurrence should be monitored and considered in future studies in order to avoid misidentification of Hesperolabops spp. Kirkaldy native populations there, and to avoid the confusion of the damage that may be caused on O. ficus-indica.

Abundance and species richness of Coreoidea (Hemiptera: Heteroptera) from Parque Estadual do Turvo, Southern Brazil

The coreoid fauna from Neotropics is poorly known, especially in terms of community studies. Aiming at contributing to this knowledge, a two-year study was carried out at Parque Estadual do Turvo, Municipality of Derrubadas, state of Rio Grande do Sul, Brazil, to evaluate the composition, abundance and species richness of Coreoidea. Samplings were conducted in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using beating tray method, along two trails of the park. Sampling effort (hours X collectors) totaled 153h. A total of 282 individuals of Coreoidea were collected, distributed in 28 species of Alydidae, Coreidae and Rhopalidae. The most abundant species was the coreid Cebrenis supina Brailovsky, representing 16% of the collected individuals, followed by the rhopalids Jadera aeola (Dallas), and Harmostes sp., with 12.1% and 11.7%, respectively. The estimated richnesses by Chao 1, Chao 2, Jackknife 1 and Jackknife 2 indicated that the observed richness corresponds to 70% to 80% of the expected for the area. The estimated richness through rarefaction was significantly higher in spring 2003 and autumn 2004 than in the other periods. There was no significant difference, however, between spring of 2003 and autumn of 2004, and between spring of 2004 and autumn of 2005, for the same parameter. Yucumã and Garcia trails did not differ significantly for the estimated richness. Singletons and doubletons represented 32.1% of the recorded species. Additionally, eight other species were obtained qualitatively by using, besides beating tray without protocol, manual collection.

Two New Species and Distribution Records of the Genus Acroleucus in Mexico (Hemiptera: Heteroptera: Lygaeidae: Lygaeinae)

Abstract The genus Acroleucus Stål from México is revised. Two new species A. calvatus and A. tensus are described and illustrated. New distribution records are presented, as well as comments on the host plants for some of the species. A revised key to Mexican species is included.

Description of Three New Species of Anasa Amyot and Serville (Hemiptera: Heteroptera: Coreidae: Coreini) from South America

Abstract Three new species of Anasa Amyot and Serville (Heteroptera: Coreidae), Anasa byssoidecerus Brailovsky and Barrera from Peru and Anasa rapax Brailovsky and Barrera and Anasa onorei Brailovsky and Barrera from Ecuador, are described. Habitus illustrations and drawings of the pronotum, male genital capsule, and paramere are provided.

Salgohygia: A New Genus of Colpurini from New Guinea (Hemiptera: Coreidae: Coreinae)

Abstract Salgohygia Brailovsky and Barrera new genus, and two new species (S. assecta Brailovsky and Barrera and S. gracilis Brailovsky and Barrera), collected in Dutch New Guinea, are described. The relationship with Sciophyrus Stål and Sciophyrella Brailovsky and Barrera is discussed. Dorsal view illustrations and drawings of male genital capsule, parameres, and female genital plates are provided.

A new species of Anasa from Honduras (Hemiptera: Heteroptera: Coreidae)

Abstract Anasa linnavuorii, a new species of Anasa Amyot and Serville, 1843 from Honduras, is described and illustrated. Dorsal view photos and a key to the known Honduran species are included.

Heteroptera attracted to butterfly traps baited with fish or shrimp carrion

Abstract Records of Heteroptera collected at butterfly traps baited with fish or shrimp carrion during collecting trips to Bolivia, Brazil, Colombia, Ecuador, and Peru are presented. Traps consisted of a cylinder of net fabric (about 35 cm diameter × 75 cm length) attached on the top and bottom to square pieces of wood slightly larger than the diameter of the cylinder. The bait usually consisted of locally available fish or shrimp that were cut into small pieces and placed in a container with water and a little soil and allowed to putrefy for several days to a week or more before use. The Heteroptera collected consisted of 91 species and 1,712 specimens in the following families: Alydidae, Coreidae, Cyrtocoridae, Lygaeidae, Miridae, Pentatomidae, Reduviidae, Rhopalidae, Rhyparochromidae, and Scutelleridae. We collected 1,356 males and 356 females at these traps, but most of the sex bias occurred in the Scutelleridae. Although sex bias was variable by family, a bias towards females generally occurred except for the Scutelleridae. Most of the species collected at these traps were not collected at the location using other collecting methods, so collecting at butterfly traps increased the number of taxa obtained at each location. Butterfly traps baited with fish or shrimp carrion should be considered as an additional collecting tool for biodiversity studies or general collecting.

Terrestrial Heteroptera (Hemiptera) from Moconá Provincial Park (Misiones, Argentina)

Mocona Provincial Park was created to protect the Paranaense forest including the Mocona Falls Natural National Monument. Knowledge of the insect fauna in the park is scarce and the Heteroptera have never been studied. In this work, 134 species from 17 families of Heteroptera collected in Mocona Provincial Park and surrounding areas included in the Yaboti Biosphere Reserve, are listed. The reduviids Arilus gallus (Stal, 1872), Repipta taurus (Fabricius, 1803), and Zelus nugax Stal, 1862; the tingids Leptodictya (Hanuala) paspalii Drake & Hambleton, 1934, and Leptopharsa vittipennis (Stal, 1873); the coreids Camptischium niger (Stal, 1870), Leptoglossus ingens (Mayr, 1865), Chariesterus cuspidatus Distant, 1892 and Cebrenis supina Brailovsky, 1995; the pentatomids Alveostethus pseudopolitus (Ruckes, 1957) and Dryptocephala integra Walker, 1867; and the blissid Xenoblissus lutzi Barber, 1954 are first records from Argentina.
