The labial palps (part of the mouthparts) are curved, sharp-tipped and the second and third segments are similar in length.

There is a pair of antennae which are shorter than the forewing, have elongate and clubbed scapes, and (in males) the flagella have long ciliae on the anterior margins.

[2] Both forewings and hindwings are lanceolate, meaning they are widest near the base and taper to points at the end.

[2][4] The male genitalia have a bell-shaped uncus that is setose laterally and tapering caudally, and is as long as the gnathos.

For example, S. auriferella is a pest of fruits and vegetables including apples, avocados, grapes, jujubes, kiwifruit, peaches and pomegranates.
