Macrodinychidae Hirschmann, 1979

Macrodinychidae Hirschmann, 1979b: 70 (nomen nudum).

Type genus Macrodinychus Berlese, 1917: 12 , by inference from the family name.

Notes. This family name was first used by Hirschmann (1979b) with four included genera, but without any description or diagnosis. At that time the family had the same taxonomic content as the Teilganggattung called Macrodinychus in Hirschmann (1979b, page 65). Farrier & Hennessey (1993), Vázquez & Klompen (2007) and Kontschán (2008a) used the family name but did not provide a description or any other taxonomic information. Beaulieu et al. (2011) used the family name but attributed the name to Hirschmann (1979b) and did not provide a description or any other taxonomic information. The genus name Macrodinychus is in widespread use, and the genus has been placed in the Uropodidae ( Gonzalez et al., 2004) , or Uropodinae ( Hiramatsu, 1980c), or left without a family placement. Hirschmann (1993), Wiśniewski & Hirschmann (1993), and Wiśniewski (1993a, 1993b, 1993c) used the genus name, but did not indicate its family placement. Kontschán (2011b) reviewed the history of the family and considered it to include only the genus Macrodinychus , with four subgenera. He provided a diagnosis of the family, but attributed the name to Hirschmann (1979b), and did not state that it was a new name, so he did not make the name available ( ICZN Article 16.1). Kontschán & Hajizadeh (2013) incorrectly referred to Macrodinychidae Hirschmann, 1975 . I have been unable to locate any description or diagnosis that would make the family name available, so it remains a nomen nudum.
