Diagnosis. The forewing length is 11 mm in both sexes. Sicciaemorpha danepan sp. n. is similar superficially to S. nebulibia sp. n., but is distinguished by the somewhat more elongate forewing with the smaller black spots at the costal margin. The male genital capsule of S. danepan sp. n. differs from those of the congeners by the wide (equal to the width of the distal lobe), almost rectangular ventro-distal process of the valva having a narrow and apically setose process originating from its disto-dorsal corner. The costal process of the new species is similar to that of S. reducta sp. n., but in S. danepan sp. n. it is longer (ca. 4/5 of the length of the distal lobe), thicker and evenly curved, whereas that of S. reducta sp. n. is shorter (ca. 1/2 of the length of the distal lobe), thinner and curved medially. The distal saccular process of S. danepan sp. n. is similar to that of S. pleiadina sp. n. The aedeagus of the new species is similar to that of S. reducta sp. n., but is somewhat shorter (in comparison to the length of the valva) and thicker, and the vesica is slightly broader. The female genitalia of S. danepan sp. n. are most similar to those of S. pleiadina sp. n., but differ by the reduction of the ventro-lateral pockets of the 7 th sternite (in S. pleiadina sp. n., they are large and well sclerotized), the conspicuously shorter antrum (ca. 1/2 of the length of the ductus bursae vs. 3/ 4 in S. pleiadina sp. n.), and the approximately twice narrower appendix bursae.

Distribution. Known from the Philippine Island of Mindanao.

Etymology. Danepan is a character of the Philippine folktale, a wife of Sayen.
