Type species. Ennada flavaria Blanchard 1852: 87 . By monotypy.

Diagnosis. The three species of the genus present large triangular forewings where the basal two-thirds is darker than the distal third. This maculation pattern contrasts with the typical transverse bands observed in other taxa of Larentiinae . The presence of M2 on both wings, the double areole on the forewing and the long fusion of Sc+R1 and Rs supports its assignment to the Larentiinae . A coniform signum in the female and an androconium in the basal third of the costa of the valvae in the male genitalia constitute the diagnostic characters of the genus.

Redescription. Head, with filiform antennae in females and pectinate or filiform antennae in males; vertex brown; labial palpi, apically brown whitish basally; brown thorax. Broad and triangular wings, brown to light brown. Male genitalia ( Figs. 9, 11 , 12, 14 , 15 and 17 ) with wide quadrangular to sub-triangular valvae, with androconia in the basal third of the costa; elongated, thin uncus; gnathos absent; tubular, simple aedeagus, vesica armed with a set of spines. Female genitalia ( Figs. 10 , 13 and 16 ) with globose, membranous corpus bursae; signum conical, sclerotized.

Distribution. Ennada is distributed between 29º and 44º S, between the provinces of Coquimbo and Chiloé, Chile ( Fig. 18 ).

Remarks. Scoble (1999) includes this genus among the Ennominae . Pitkin (2002) transferred it into the Larentiinae .
