Diagnosis. This species is superficially similar to D. galbinea Park , sp. nov., but it can be distinguished from the latter by the forewing with well-developed, orange-white postmedian band present, and the male genitalia differ from the two preceding new species with very elongated valva and the juxta rounded on caudal margin.

Description. Male ( Fig. 4A View FIGURE 4 ). Wingspan 22.0 mm. Head: Pale yellow dorsally. Antenna about 2/3 of forewing; basal segment elongated, pale yellow all around; flagellum pale yellow throughout, without distinct annulations, finely ciliate. Second palpomere of labial palpus thickened, arched, shiny, pale yellow all around; 3 rd palpomere slender, strongly upturned, as long as 2 nd palpomere, pale yellow. Thorax: Tegula pale yellow, with fuscous scales anteriorly; thorax pale yellow dorsally. Hind tibia roughly scaled with pale yellowish, strong setae dorsally; yellowish white on outer surface. Forewing ground color pale greyish orange; antemedian band yellowish white, slightly broadened toward costa; postmedian band well-developed, orange-white, zigzagged, slightly broader in anterior half; costa slightly arched in basal 1/3, then nearly straight, slightly oblique beyond 3/4; apex obtuse; termen oblique; fringe paler in basal 1/3, then concolorous with ground color. Hind wing evenly yellowish white. Abdomen ( Fig. 4F View FIGURE 4 ): Spinous zones sparsely set with strong spines; tergite VIII with narrowly widened sclerite along posterior margin; sternite VIII not specifically modified.

Male genitalia ( Figs 4 View FIGURE 4 C–E): Uncus extremely elongate, parallel sided, gently bent medially, reaching apex of basal plate of gnathos, apex acute. Basal plate of gnathos large, with long basal arms, narrowed apically; median process short, bent beyond middle, with sharply pointed apex. Tegumen sclerotized, with roundly concave anterior margin. Valva extremely elongated, with arched cucullus; costa with small basal expansion anteriorly, then concave; ventral margin slightly concave basally; sacculus weakly developed, nearly invisible; cucullus elongated, densely setose, with arched outer margin, with round apex. Juxta with rounded caudal margin, weakly sclerotized along caudal margin. Vinculum narrowly banded. Aedeagus more or less slender, shorter than valva, apical protrusion of dorsal surface ladle-like, upturned.

Female unknown.

Distribution. Kenya (Central).

Etymology. This species name is derived from the Latin, saltus (= forest, woodland), with a Latin suffix, - alis, referring to the collecting site of the forest.
