Distribution. Argentina: Salta, Tucumán, Catamarca, La Rioja, Santiago del Estero, Córdoba, San Juan, and Mendoza provinces.
Habitat. This species occurs in xerophilous warm steppes and dry forests east of the Andes, in the biogeographic provinces of Monte and Chaco (Morrone 2014) at altitudes of 150 to 2,400 m. Specimens were collected throughout the year, even in the coldest months.
Biology. Specimens collected in Mendoza at the Science and Technology Center (91 individuals) were found feeding on decomposing pig carcasses, mainly on the carcass in direct sunlight (88 individuals) and very few on the carcass in the shade (3 individuals). These specimens were recorded in greatest abundance in autumn (46 individuals) and spring (44 individuals), with only one record in the winter and none in the summer. This species was associated with the Advanced Decay and Dry Remains stages of decomposition defined by Payne (1965).
Because of these three behavioral characteristics, 1) preference for carcasses under direct sun, 2) seasonality (autumn and spring), and 3) association with specific stages of decomposition (Advanced Decay and Dry Remains), this species should be considered for potential forensic importance for estimating time of death (PMI = Post Mortem Interval) in bodies found in arid environments.
Specimens that were collected using pitfall traps partly filled with water and propylene glycol in two reserves of Mendoza province, Telteca and Ñacuñán, could have been attracted by the smell of decomposition of propylene glycol, similar to the smell of a carcass.
