First record of Phitacnemia picta (Drury, 1770) (Heteroptera: Coreidae), in the province of La Pampa, Argentina. Munis Entomology & Zoology, 9 (1): 376-378]  ABSTRACT: We report the first record of Phitacnemia picta capture (Drury, 1770) (Heteroptera: Coreidae) for the province of La Pampa. This species has economic importance attacking ornamental and fruit crops. This record brings the number of species of Heteroptera in the province.  KEY WORDS: Coreidae, Heteroptera, phytophagous, passionflower, Phitacnemia picta.  The Heteroptera, with over of 40,000 species, are part of the most successful group of hexapods. They are predominantly herbivorous. The arthropods of the superfamily Coreoidea are generally of habits phytophagous and economic importance (Cobben, 1978), attacking crops Fabaceae, Cucurbitaceae, passifloraceae, Solanaceae, etc. (Maes, J. M. & J. Tellez Robleto, 1988). Within this superfamily, we highlight the family Coreidae as detrimental to ornamental plants and fruit, appearing within this family at the species Phthiacnemia picta (Drury, 1770), found on the vegetation (Maes, J. M & U. goellner-Scheiding 1993; Schaefer & Mitchell, 1893). In Passiflora (Passifloraceae: Passiflora), located in Realicó, (La Pampa, Argentina) (35 ° 1 'S 64 º 15' W) in the month of March 2011 were found individuals to the species P. picta, taxon unregistered for the province of La Pampa. This species is widely distributed throughout the Neotropics (Osuna, 1981). Knowing the distribution of Phitacnemia picta in a given area is of vital importance, because this heteroptera can cause economic loss, in crops of Passiflora. These insects damage the crop by suck the juices from the developing fruit. Mechanical damage of the seed caused by bugs allows infection and colonization by fungi, bacteria and viruses, in addition to reducing the yield and seed (Serra, 2009). The present contribution have from objective publicize the new record of the species Phthiacnemia picta, for the province of La Pampa.  MATERIALS AND METHODS  The material was collected on a flower of the Passiflora sp. located in Realicó (La Pampa, Argentina) (35 ° 1 'S 64 º 15' W) in the month of March 2011. Both the adult and stages immature of Phthiacnemia picta Dury, were obtained by direct capture with a deadly bottle, then were placed in 70% alcohol for preservation. The adults were identified to level species using a dichotomous key Brailovsky (2009) and the material was deposited in the Museum of Natural Sciences of La Plata. _____________Mun. Ent. Zool.
