Remarks: Macrobiotus coronatus has a relatively wide distribution, but Pilato et al. (2000) suggested that only the South American localities are correct and all others need to be confirmed. This species belongs to the Macrobiotus harmsworthi group that require careful examination to ensure correct identifications (see Kaczmarek et al. 2011 for a diagnostic key to the group).
