Elachista amideta Braun 1948

Elachista amideta new species (Fig. 88.)
Head pale gray (the scales white, minutely tipped with gray) ; palpi white, the second segment dark gray beneath and outwardly, third segment gray outwardly except at base ; antennae pale gray, fuscous toward tips. Scales of the thorax and fore wings white with pale gray tips, producing the effect of a pale gray ground color; the costal area, especially near base, from costal margin to the upper margin of the cell is somewhat darker than the remainder of the wing; darker and more broadly gray-tipped scales form indistinct longitudinal lines on the wing; one of these lies just above the fold, and is directed toward apex, nearly joining a short line of dark scales which extends to the extreme tip of the wing and is continued as a dark pencil in the apical cilia ; a third dark line runs below the fold, meeting it at the wing margin. Cilia grayish white except opposite the apex. Legs pale gray, tips of segments white. Abdomen gray mid-dorsally, elsewhere white.
Alar expanse : 9.2 mm.
Male genitalia (fig. 88) similar to cana, but with the space between the uncus lobes parabolic in shape; harpe more slender; anellus broader with more transverse wrinkles; aedeagus much more slender in the outer half, cornutus a short bent spine, stouter than in cana.
Type. — S , Ottawa, Ontario, May 15, 1933 (C. H. Young), [Can. Nat. Coll., Type No. 5743].
Paratype. — $ , same data as the type [C. N. Coll., No. 5743].
Food plant and early stages unknown.
In the type the longitudinal lines of darker scales on the fore wing are more apparent than in the paratype. E. amideta is nearest to E. cana from which it is distinguished by the general gray color in contrast to the white color of that species ; in the male by differences in genitalia, as noted.

Elachista amideta is a moth of the family Elachistidae. It is found in Canada, where it has been recorded from Ontario.

The wingspan is about 9.2 mm. The forewing have white scales with pale grey tips, giving the wing a pale grey appearance. The costal area is somewhat darker than the remainder of the wing. Darker and grey-tipped scales form indistinct longitudinal lines on the wing.
