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

Moconá Provincial Park was created to protect the Paranaense forest including the Moconá 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 Moconá Provincial Park and surrounding areas included in the Yabotí Biosphere Reserve, are listed. The reduviids Arilus gallus (Stål, 1872), Repipta taurus (Fabricius, 1803), and Zelus nugax Stål, 1862; the tingids Leptodictya (Hanuala) paspalii Drake & Hambleton, 1934, and Leptopharsa vittipennis (Stål, 1873); the coreids Camptischium niger (Stål, 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.

The South American Atlantic Forest is one of the largest and more threatened tropical rainforests in the world, as only remains 7% of its original extension (Plací and Di Bitetti 2005).This complex of ecoregions has been identified as one of the world biodiversity hotspots (Myers et al. 2000;Mittermeier et al. 2004).Despite its highly fragmented condition, the Atlantic Forest is still one of the most diverse biological ecosystems of the earth, containing 7% of the world's species (Cullen et al. 2001); with a high level of endemisms: 40% of plants, 42% of terrestrial vertebrates (Myers et al. 2000), 74% of bromeliads, 80% of primate species, and 92% of amphibians (Mittermeier et al. 1999;Valladares-Padua et al. 2002).
The two largest Atlantic Forest remnants, that accomplish near 10,000 km 2 each, are located in the Serra do Mar in the states of São Paulo and Paraná in Brazil, and through most of Misiones province in Argentina (Galindo-Leal and Câmara 2003;Giraudo et al. 2003).The Atlantic Forest complex includes fifteen ecoregions, the largest one is the Parana Forest, also known as the Atlantic Forest of Alto Parana, that extends from the western slopes of the Serra do Mar, in Brazil to eastern Paraguay and the province of Misiones in Argentina.
The conservation of Argentinean remnants of the Parana Forest is a key issue to maintain complete species assemblages, where ecological and evolutionary processes are proceeding unabated (Galindo-Leal and Câmara 2003;Giraudo et al. 2003Giraudo et al. , 2008)).Knowledge of biodiversity in protected areas in Argentina is very limited, and has focused mainly on vertebrate taxa.Despite being the most diverse animal group, arthropods have been and remain minimally represented in biodiversity inventories ; insects -as the most speciesrich and ecologically varied and complex components of animal biodiversity -cannot be disregarded in assessing impacts of the environmental changes (New 2012).
Moconá Provincial Park was created in 1988 to protect the Paranaense forest including the Moconá Falls Natural National Monument (Ley Nacional N° 24.288).It covers about 1,000 ha of the southeastern part of the UNESCO Yabotí Biosphere Reserve, San Pedro Department, Misiones Province, Argentina (27˚08′ S/ 27˚11′ S -053˚53′ W/053˚56′ W).
The knowledge about the insect fauna in the park is limited, and the Heteroptera have never been studied.Recent papers recorded five species from Moconá, two new to science (Montemayor and Dellapé 2011; Dellapé

MATERIAL AND METHODS
Four field trips of about 10 days each were conducted to the Moconá Provincial Park (Figure 1), during III-2010, X-2010, III-2011, and III/IV-2012.Most of the specimens were collected using sweeping and beating nets; complementary collection was done by hand directly on the ground and visual inspection at light traps.Adults were preserved in 96% ethanol in the field, then mounted in the lab, and examined under a Nikon SMZ 1000 stereomicroscope.Whenever required to confirm identification, the genital capsule (in males) and genital segments (in females) were dissected and cleared with a saturated potassium hydroxide solution for observation; dissected genitalia were posteriorly preserved in microvials with glycerin.All specimens were deposited in the Entomological collection of the Museo de La Plata, Buenos Aires, Argentina (MLP).We also studied the Entomological collections of Museo Argentino de Ciencias Naturales, Buenos Aires, Argentina, (MACN), Instituto Miguel Lillo, Tucumán, Argentina (IMLA), and MLP.Additional specimens of the families Anthocoridae, Nabidae, Miridae, Thyreocoridae and Cyrtocoridae that were collected and not included in the present paper are deposited in MLP.

DISCUSSION
In the present inventory, 134 species from Moconá Provincial Park and surrounding areas inside the Yabotí Biosphere Reserve (Figure 1) are listed.For most families some material remains undetermined and is being studied as they could be new taxa.
