Diagnosis. This species is morphologically similar to Bucculatrix tsurubamella Kobayashi et al., 2010, but differs in having a single band-like signum centrally located in the corpus bursae of female genitalia, unlike B. tsurubamella, which has a membranous structure in this region. Furthermore, this new species is distinguished by the upper part of the corpus bursae, which is slightly folded and has multiple longitudinal rows of signa arranged in parallel. This set of features clearly differentiates it from B. tsurubamella.
Description. Adult (Fig. 2A). Wingspan 6.5–7.0 mm.
Head: White and composed of densely covered with tufts of scales; frons white; antennae white, with pale orange rings, extending approximately 3/5 of the forewing length; eye caps white, mixed with orange scales.
Thorax: Creamy white, mixed with pale brown scales; tegulae covered with creamy white scales. Legs fuscous and white; fore coxa fuscous with long and greyish black scales apically; hind coxa pale ochreous with blackish spots apically. Forewing ground colour fuscous white with several orange mixed with black spots basally, at 1/3, 2/3 and along the apical margin; a broken orange stripe in the central area; a second orange stripe extends from two-thirds of the length of the costa; apex covered with black scales, scattered with pale orange spots; cilia white, extending along the wing margins. Hindwings white and lanceolate, with a silky sheen.
Abdomen: Grey with a yellowish hue.
Male genitalia. Unknown.
Female genitalia (Fig. 3A). Papillae anales sclerotised, broadly oval, densely covered with short hairs uniformly distributed across the surface.Apophyses anteriores absent; apophyses posteriores slender and elongated. Ostium bursae broad and funnel-shaped, with margins strongly sclerotized and distinctly visible; antrum elongated and triangular. Ductus bursae membranous, slender, weakly sclerotized, gradually widening near the opening, and gradually narrowing toward the corpus bursae. Corpus bursae elongated, oval-shaped, membranous, with a single row of comb-like signum structures running along with a centrally positioned band. Ductus seminalis slender, originating near the junction of the ductus bursae and corpus bursae.
DNA barcodes. This new species, Bucculatrix koreana sp. nov., has a genetic distance of 6% from B. tsurubamella, showing a distinct genetic divergence from neighbouring species in Korea. The sequence of B. koreana sp. nov. has been registered in NCBI (Accession number: PQ304121).
Distribution. Korea.
Host plants. Unknown.
Etymology. The species name is derived from the type locality (Korea) of this new species.
