218. 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.
