Paratypes (3 ♁, 1 ♀): MICRONESIA, KOSRAE: 1 ♁, 1 ♀, same data as holotype, Genitalia slide no. DIC-038, 041; 2 ♁, Utwa, Sipyen waterfall, 10. XI. 2022, (Jung S.W., Kim Y.H., Ko J.H.), (N5˚17’02.9″, E162˚57’25.5″ Alt: 17m), Genitalia slide no. DIC-037, 040.
Diagnosis. Haritalodes kosralis sp. nov. is similar to H. derogata (Fabricius, 1775), but can be distinguished by the following characteristics: the marginal shade on the forewing is brown with a light yellow at the apex; the hindwing pattern is darker and wider than that of H. derogata (fig. 1); in the male genitalia, the uncus is narrower than that of H. derogata overall and pointed at the apex; the dorsal process of the fibula is hooked (fig. 3); in the female genitalia, the signum of the corpus bursae is absent (fig. 4). As for H. derogata, the brown marginal shade on the wings is absent; the hindwing pattern is lighter and narrower than that of H. kosralis sp. nov. (Yamanaka, 2008, Figs. 1–2); in the male genitalia, the uncus is wider than that of H. kosralis sp. nov. overall and rounded at the apex; the dorsal process of the fibula is needle-shaped (Yamanaka, 2008, Fig. 9); in the female genitalia, two semicircular signa of the corpus bursae are present (Yamanaka, 2008, fig. 13).
Description. Adult (Figs. 1–2). Length of forewing 10–11 mm in both sexes. Vertex and frons covered with light yellow scales; antenna filiform; maxillary palpus brown mixed with yellow scales; labial palpus upturned, first segment brown mixed with light yellow scales, second and third segments covered with light yellow scales. Patagium and tegula light yellow. Ground color of forewing light yellow; basal area with a brown spot near posterior margin; antemedial line brown; antemedial area with a brown orbicular and subreniform spots; median area with a brown reniform spot; brown postmedial fascia irregular pattern from 3/5 of costal margin to 1/2 of posterior margin and outwardly oblique from 3/5 of costal margin to 2/3 of M 1, irregular zigzag from 2/3 of M 1 to 1/2 of CuA 1, angled at 1/4 and 1/2 of CuA 1; marginal shade brown, except light yellow at apex; fringe brown mixed with light yellow. Ground color of hindwing light yellow; brown antemedial and median fascia ill-defined and connected brown discal spot; marginal shade brown except light yellow tornus or brown marginal shade with light yellow irregular patches in the intervals and light yellow tornus. Abdomen slender, covered with light yellow scales; dorsal part of third segment with a brown line; dorsal area of seventh segment with a brown or dark brown rectangular patch.
Male genitalia (Fig. 3). Uncus narrowly triangular and apex pointed, sparsely setose; valva nearly spatulate, emarginate near 1/4 of costa, densely setose overall; fibula with ventral and dorsal processes, ventral process convex prominent, oblique at exterior edge, directed dorsally towards uncus and dorsal process hooked, directed towards distal valva; sacculus sclerotized, sparsely setose, and saccular process small, club-shaped, with setae; juxta shield-shaped; saccus Ushaped; coremata with densely long hairs; phallus cylindrical, anterior half sclerotized.
Female genitalia (Fig. 4). Papillae analis simple; posterior apophyses almost same length as anterior apophyses; antrum broad, strongly sclerotized; ductus bursae membranous, as broad as antrum, about twice the length of corpus bursae; corpus bursae ovoid, membranous, without signum; appendix bursae absent.
Distribution. Micronesia (Kosrae).
Etymology. The specific name was derived from the type locality, Kosrae, Micronesia.
