Macrobiotus nuragicus Pilato & Sperlinga, 1975 sensu lato [T] Terra typica : Italy (Europe) Argentina : 41°14′S , 71°18′W ; 1,050 m asl: Rio Negro Province, Challuaco stream, mosses from rock in water. Rossi & Claps (1991) Record numbers: Argentina : 1; total: 1. Remarks: This species belongs to the harmsworthi group and has a rather disjunct distribution ( McInnes 1994a ). The group requires careful taxonomic analysis including egg morphology ( Kaczmarek et al. 2011 ). The South American record is a potential misidentification.
