Natural History. Odo patricius lives associated with Tillandsia spp. (Bromeliaceae) in the mountain coast, under stones on beaches and in Prosopis tamarugo (Fabaceae) forest in the north of Chile. Specimens have been collected manually on soil and with pitfalls traps. They are found from sea level to altitudes above 3700 m.
Distribution. South American, from central to north Chile and southern Peru.
