Remarks

Austroregia huxleyana ( Bate, 1862)   basically agrees with the description of J.L. Barnard (1989), except in the mandibular palp; the studied material has two outer basal setae on the third article instead of outer margin naked. This species is widely distributed in southern South America, extending its distributional limits to some localities of Santa Cruz, Chubut and Río Negro provinces, which are mentioned for the first time.
