The Natural Protected Area “Península Valdés” (ANP-PV), the largest conservation unit for arid ecosystems in Argentina, is located in the northeastern zone of this biome. It is a wide plateau, extending 4,000 km2 in the NE of Chubut Province, and it has been included in the UNESCO’s World Heritage List since 1999. The Oxycarenidae is a cosmopolitan group of usually small, flattened lygaeoid bugs. This family is poorly represented in the Western Hemisphere, where it contains five genera and 20 species. Two of these genera include introduced species, namely Oxycarenus hyalinipennis (Costa) now occurring in Argentina, Paraguay, Bolivia, Brazil, and the West Indies, and Metopoplax ditomoides (Costa), which has recently been recorded by Lattin (2002) from established populations in the United States of America. In addition to the exotic taxa, Dycoderus Uhler with D. picturatus Uhler, known from North America, and Neoplax Slater with Neoplax mexicana Slater from Mexico are both monotypic genera. The fifth genus, the most speciose, is Anomaloptera Amyot & Serville. Hoberlandt (1987) synonymized the Western Hemisphere Crophius Stål with the Palearctic Anomaloptera based mainly on characters of the coleopteroid forms; thus, the genus comprises 18 species of which 16 are distributed in the Western Hemisphere; two of these occur in Argentina. The American species of Anomaloptera were reviewed by Van Duzee (1909) and Barber (1938), although both authors omitted A. leucocnemis (Berg) from Buenos Aires Province (Argentina). Kormilev (1950) described A. coleopteroides from specimens collected near Buenos Aires city and compared it with the other Argentinean species, A. leucocnemis, which he redescribed in the same paper. The junior author performed extensive collections using pitfall traps in Península Valdés (Chubut: Argentina) from 2003 to 2006.  A new species of a coleopteroid Oxycarenidae was among the taxa collected, and is herein described and illustrated. A key to recognize the four Argentinean species of the family is given.
