Diagnosis. The species is externally similar to and comparable with C. striatipennella Nylander, 1848 , and C. algidella Staudinger, 1857 , in sharing genital characteristics, such as a robust expansion of the dorsal corner of the sacculus in the male genitalia, and a trapezoidal sterigma with a rounded fold on each side of the colliculum, as well as leaf-like signum in the female genitalia. However, it can be easily identified from the latter by the following genital characteristics: 1) in the male genitalia of C. albicans , the sacculus features a dorsal corner expansion having three processes, one of which is near the dorsal base, the second one is next to the dorsal one, and the third is the most robust ventral one, the sacculus lacks a ventral expansion, two juxtal rods of the phallotheca are asymmetrical, one of which is weakly constricted at the middle, slightly spiraled, and curved downward with a pointed apex, while the other is distinctly about 0.5× shorter than the former, also with a pointed apex, and the cornutus consists of two spines joined together with their enlarged bases, while in C. striatipennella (see Baldizzone 2019: Pl. GM LXXVII, Fig. 244) and C. algidella (see Baldizzone 2019: Pl. GM LXXVII, Fig. 245), male genitalia possess the sacculus with a triangular expansion containing three processes, the middle of which is the most robust among three, the sacculus itself with a triangular expansion having a rounded apex, two juxtal rods, one of which has triangular teeth and is slightly shorter than the other, and the cornutus which is slender and long; 2) in the female genitalia of C. albicans (see Baldizzone 2019: Pl. GF LXXXII, Fig. 244), sterigma with two longitudinal crescent folds on each side of the colliculum, which are situated in the anterior half of the sterigma, a bulged colliculum on the anterior half, and the ductus bursae with two sclerotized ovaloid formations at the posterior part of the ductus bursae, which are not parallel and are covered with spines, are present, while in C. striatipennella (see Baldizzone 2019: Pl. GF LXXX, Fig. 240) and C. algidella (see Baldizzone 2019: Pl. GF LXXXI, Fig. 241), female genitalia possess the sterigma with a crescent fold on each side of the colliculum, which extends along the entire length of the sterigma, the colliculum without such bulging, and the ductus bursae with much longer spinulate section consisting of two parallel bands.

Adult ( Figs 8B ; 11B ): Forewing length 5.5–6.5 mm (wingspan 11.0–12.0 mm) (n=3) ( Li 2012: wingspan 11.0– 13.5 mm; Oku 2013: wingspan 10.0–14.0 mm; Baldizzone 2019: wingspan 10.0–13.0 mm). See also Kim & Park (2009: Fig. 2 ); Li (2012: Pl. V, Fig. 106); Oku (2013: Figs 3 -31-24, 25); Park (2014: Pl. for adults, Fig. 3 ); Baldizzone (2019: Pl. AD XLIV, Fig. 254).

Male genitalia ( Figs 13C, D ; 21B ): See also Park & Baldizzone (1992: Figs 13, 13a : misidentified as C. granulatella ); Kim & Park (2009: Figs 29–29b ); Li (2012: Fig. 106A); Oku (2013: Fig. Col1-17); Park (2014: Fig. 3 ); Baldizzone (2019: Pl. GM LXXVIII, Fig. 248).

Female genitalia: See Kim & Park (2009: Fig. 50); Li (2012: Fig. 106B); Oku (2013: Fig. Col2-18); Baldizzone (2019: Pl. GF LXXXII, Fig. 244).

Larval case [leaf (early stage), flower and seed (late stage) miner]: Tubular silken case (trivalved). See Baldizzone (2019: Pl. AST XXX, Fig. 219); Jinbo & Suzuki (2023).

Host plants. [ Asteraceae ] Artemisia campestris L., A. absinthium L., A. maritima L. ( Falkovitsh 2006; Baldizzone 2019), and A. montana (Nakai) Pamp. ( Oku 2013) .

Distribution. Almost all of Europe, Ukraine, Russia (Western and Southern European part, Southern Siberia, Far East), Turkey, China, Japan, Korea ( Kim & Park 2009; Park 2014; Anikin 2019; Baldizzone 2019; Anikin & Knyazev 2024).

Remarks. The species was first reported from Korea by Kim & Park (2009). At one point, this species was erroneously identified by several authors as C. granulatella Zeller, 1849 , subsequently regarded as a junior synonym of C. granulatella . Probably for this reason, Park & Baldizzone (1992) initially reported the species from Korea as C. granulatella Zeller, 1849 , but it was later identified as a misidentification of C. albicans .
