Distribution Disjunct range between Parapielus luteicornis in Tierra del Fuego and southern Patagonia, and three species in Chile and Argentina north of 43°S, mostly west of the Andean divide (Nielsen and Robinson, 1983).
Systematics Monophyly requires substantiation. Nielsen & Kristensen (1983: p. 49) identify two characters but these are problematic: (1) Valves short, broad as long – no comparisons with other Hepialidae; (2) Mesosome [pseudotegumen] without spout-shaped ventral lip – also applicable to various other genera. In neither case is there comparison with a hepialid outgroup.
Habitat Forest, with the exception of Parapielus luteicornis recorded from grass-steppe habitats in Tierra del Fuego and southern Patagonia (Nielsen and Kristensen, 1983).
Biology Immature stages unknown. Adults fly from mid-summer to late autumn (Nielsen & Robinson, 1983). In the apparent absence of stem boring Hepialidae from southern South America, larvae are likely to excavate tunnels in the soil.
