This species inhabits open spaces on mountains on the forest edge at 3000 ft altitude.
This species was first described by Edward Meyrick in 1911, collected by George Hudson at Mount Holdsworth, Tararua Range at 3000 ft in February, and named Simaethis iochondra.
Forewings suboblong, moderate, costa moderately arched, apex obtuse, termen rounded, oblique; dark bronzy-brown; basal area sprinkled with violet-whitish specks; a very undefined irregularly dentate shade of violet-whitish specks from 2⁄5 of costa to middle of dorsum; an irregular fascia of violet-whitish specks at 3⁄4, constricted above middle, dilated on dorsum so as to coalesce with preceding shade; a light brownish-ochreous patch in disc between these; a terminal streak of ochreous-brown suffusion: cilia ochreous-brownish, mixed with darker at apex and tornus, tips whitish.
Hindwings ovatetriangular, termen slightly rounded, hardly perceptibly sinuate; dark fuscous; cilia grey, with dark-fuscous subbasal shade, tips whitish.
