According to Morrone (2004, 2006) this area is located in the Subandean Patagonia province, Andean region, Patagonian Subregion. This National Park is one of the biggest in Argentina, with an extension of approximatelyħ09.886 hectares, and extends between the provinces of Río Negro and Neuquén. Specimens were captured with Malaise traps located on the west side of the Nahuel Huapi National Park (NHNP). In this paper I describe a new species of Desmioza, based on male and female characteristics, from Nahuel Huapi National Park, Río Negro province, Argentina. The 2 species described before and the one described here have been recorded for the southern part of South America, more specifically from Patagonian Argentina. Desmioza is distinguished by the following characteristics: head with same coloration above and below eyes, eyes separated, interocular suture present, eye bridge with 3 facet rows, antennae shorter than wing width, flagellomeres fusiform or barrel shaped, simple unbranched ascoids, wing with infuscate patterns, costa without second costal node, R 5 ending beyond the wing tip, a spur at the base of R 3, anterior gonocoxal apodemes expanded, plate like, paramere absent, and aedeagus asymmetrical (Quate & Brown, 2004). edwardsi (Tonnoir), and transferred to Desmioza another species described by Tonnoir (1929): Pericoma speciosa they also described for the first time the male of the latter species. Then, Quate and Brown (2004) re-established Desmioza as a valid genus, included D. Subsequently Quate (1963) treated Desmioza as a synonym of Pericoma Walker and mentioned that some of the unique characters of Desmioza species were "of no more than specific rank". The genus Desmioza was proposed by Enderlein (1937) to include a previously described species by Tonnoir (1929): Pericoma edwardsi from Bariloche, Argentina. Palabras clave: sicódinos, Desmioza, clave dicotómica, taxonomía, Patagonia. Se incluye una clave dicotómica para la identificación de todas las especies conocidas del género. Esta es la tercera especie del género descrita en la región Andina, subregión Patagónica. Los adultos fueron colectados con trampas Malaise ubicadas en el Parque Nacional Nahuel Huapí, en la Patagonia argentina. Se describe una nueva especie de Desmioza Enderlein, 1937 de la Argentina: Desmioza biancae n.sp. Key words: moth fly, Desmioza, dichotomous key, taxonomy, Patagonia. A dichotomous key for the identification of all known species of the genus is included. This is the third species of the genus described in the Andean region, Patagonian subregion. Adults were collected with Malaise traps in the Nahuel Huapi National Park, in the Argentinean Patagonia. * 01 abril 2014Ī new species of Desmioza Enderlein, 1937 from Argentina is described: Desmioza biancae n.sp.
