Richters (1908a) Record numbers: Argentina: 4; total: 4. Remarks: With the New Zealand reference re-examined and re-attributed (Pilato et al. 2006), this species is only known from type locality and a doubtful site in Greece (McInnes 1994a). Some authors have suggested this species is a variant of Macrobiotus furciger or M. porteri (e.g. Mihelčič 1972, Ramazzotti and Maucci 1983), and therefore in need of revision.
