Sigelgaita Heinrich, 1939, Proc. U.S. Natl. Mus., 86: 382.
Type species: Sigelgaita chilensis Heinrich, 1939. Original designation.
Sigelgaita can be distinguished by the following combination of characters: 1) antenna of the male bipectinate, 2) maxillary palpus very long with a pointed tuft of scales distally, generally extending above top of the eye, 3) forewing M2 and M3 sharing a common stem, but separate for more than half their length, 4) hind wing M2+3 and CuA1 fused basally sharing a common stem, 5) male abdomen 8 with two pairs of thin scale tufts, 6) male genitalia rather elongate with large, long saccus and long, relatively slender uncus (Heinrich 1939; 1956; Neunzig 1997; Simonsen 2008).
According to Dodd (1940) the larvae are blue or blue-green without bands or spots.
The larvae feed on Eulynchina, Echinopsis, and Platyopuntia (Mann 1969).
Eggs are unknown. The larvae are solitary fruit feeders (Heinrich 1939; 1956; Mann 1969).
Sigelgaita is known from Chile and Peru (Heinrich 1939; 1956; Mann 1969).
