Dactylobiotus macronyx ( Dujardin, 1851 ) sensu lato [F] Macrobiotus macronyx Duj. ( Daday 1905 ) Terra typica : France (Europe) Paraguay : 24°05′S , 57°12′W ; 50 m asl : San Pedro Department, Puerto Antequera, Curuzu-chica, dead branch of Rio Paraguay . Daday (1905) Record numbers: Paraguay : 1; total: 1. Remarks: This is the nominal species of the genus, with as yet an uncertain diagnosis (e.g. Murray 1907f , Binda & Pilato 1999a , Kaczmarek et al. 2012b). Known mainly from the Holarctic ( McInnes 1994a ) and, according to Marcus (1936) , this Daday (1905) report should be considered doubtful.
