Abstract
Saridoscelis Meyrick, 1894 belongs to Yponomeutidae, with 9 described species. A new species, Saridoscelis diffusolinearum Lu & Hsu, sp. nov., is described from Taiwan, with diagnostic characters provided for both sexes herein. We also proposed that S. diffusolinearum sp. nov. is close related to S. kodamai Moriuti, 1961. The new species feeds on a subalpine bush Gaultheria cumingiana Vidal (Ericaceae) further indicating that the host plant of the subfamily Saridoscelinae may restricted to Ericaceae.

Saridoscelis diffusolinearum Lu & Hsu, sp. nov.
臺灣散紋燕白巢蛾
Diagnosis: This new species is similar to Saridoscelis
kodamai Moriuti, 1961, both in external features and
genitalia. The forewing upperside of S. diffusolinearum
sp. nov. is dusted with gray scalings, decorated with a
dark gray streak. By contrast, that of S. kodamai is
without gray, with streaks paler in coloration. In male
genitalia, the valva of S. diffusolinearum sp. nov. does not
possess a medial hump found in S. kodamai, with the
gnathos of the former longer than the latter. ...
Etymology: The name is a combination of two Latin
wards diffusa and linea, meaning spread out and line
respectively, because of the diffused, inconspicuous grey
and ocherous scales overlaid on forewing uppersides,
with presence of prominent dark streaks.
