Male genitalia slide USNM 24264. Harpe about twice length of tegumen, of nearly equal width throughout; cucullus rounded; at base, just inside sacculus, a cluster of sharply pointed stout setae. Gnathos a pair of spined knobs. Uncus as long as tegumen, rather narrow, bluntly pointed distally. Vinculum U-shaped. Tegumen about as long as broad; outer surface granular. Anellus a broadly crescentic plate with a fleshy lobe on each side at base. Aedeagus stout, curved, pointed; vesica armed with a pair of pear-shaped cornuti.

HOLOTYPE.—USNM 73709.

TYPE-LOCALITY.—Centro-Austral.

Described from the unique male holotype (Jan–Mar 1898, V. Izquerdo).

This species is nearest D. eremnogramma, new species, but the setal cluster of harpe of D. trachycantha is much nearer sacculus than in D. eremnogramma and the latter has a single long cornutus, not two as in D. trachycantha. The genitalia, with double gnathos, is atypical but on all other characters the species belongs here.

Doina trachycantha is a moth in the family Depressariidae. It was described by John Frederick Gates Clarke in 1978. It is found in Chile.

The wingspan is about 26 mm. The forewings are buff with tawny suffusion along the costa. The surface of the wing is sprinkled with tawny irrorations (sprinkles) and in the middle of the cell is a slender fuscous streak. A small fuscous spot followed by tawny is found at the end of the cell and from just before the apex, on the costa, around the tornus, is a series of small fuscous spots between the veins. The hindwings are very pale cinereous with slight greyish suffusion.
