Diagnosis. The species is externally similar to C. chenopodii Oku, 1965 and C. tyrrhaenica Amsel, 1952 . Additionally, the male genitalia of C. chenopodii (see Oku 2013: Fig. Col1-15) closely resemble those of C. adspersella , making the diagnosis challenging. However, C. adspersella can be distinguished from C. chenopodii by the following characteristics: 1) in the male genitalia of C. adspersella , a robust dorsal process of the sacculus with a dentate outer edge, except for an elongated expansion that exceeds the costa of the cucullus, is present, while in C. tyrrhaenica (see Baldizzone 2019: Pl. GM LXXXII, Fig. 258), male genitalia possess a robust dorsal process of the sacculus with a dentate outer edge, except at the subapex which is with a stout expansion, and the apex does not exceed the costa of the cucullus; 2) in the female genitalia of C. adspersella (see Baldizzone 2019: Pl. GF LXXXV, Fig. 255), the sterigma without any folds, an asymmetrical colliculum that is gradually transparent anteriorly beyond the half, and the corpus bursae with a leaf-like signum are present, while in C. chenopodii Oku, 1965 (see Oku 2013: Fig. Col2-16), female genitalia possess a relatively smaller ostium bursae, an asymmetrical colliculum that is evenly sclerotized in the posterior 1/4, and is laterally sclerotized in the rest, and in C. tyrrhaenica (see Baldizzone 2019: Pl. GF LXXXV, Fig. 254), female genitalia possess the sterigma with a fold having rounded lamella on each side of the ostium bursae, an asymmetrical colliculum that is sclerotized entirely, and the corpus bursae with two signa.

Adult ( Figs 8A ; 11A ): Forewing length 5.0 mm (wingspan 11.0 mm) (n=1) ( Toll 1953: wingspan 11.0–15.0 mm; Li 2012: wingspan 14.0 mm; Baldizzone 2019: wingspan 13.0–16.0 mm). See also Kim & Park (2009: Fig. 1 ); Li (2012: Pl. V, Fig. 108); Park (2014: Pl. for adults, Fig. 2 ); Baldizzone (2019: Pl. AD XLV, Fig. 265).

Male genitalia ( Figs 13A, B ; 21A ): See also Benander (1939: Pl. V, Fig. 70); Toll (1942b: Fig. 5 ); Toll (1953: Fig. 155); Patzak (1974: Fig. 225); Kim & Park (2009: Figs 28–28b ); Li (2012: Fig. 108); Park (2014: Fig. 2 ); Baldizzone (2019: Pl. GM LXXXII, Fig. 259).

Female genitalia: See Toll (1942b: Fig. 6 ); Hackman (1945: Fig. 160); Toll (1953: Fig. 308); Patzak (1974: Fig. 356); Baldizzone (2019: Pl. GF LXXXV, Fig. 255).

Larval case (seed miner) ( Figs 26C–E ): Tubular silken case (trivalved). See also Toll (1942b: Fig. 7 ); Toll (1962: Pl. 7 S, Fig. 90); Baldizzone (2019: Pl. AST XXXI, Fig. 230).

Host plants. [ Amaranthaceae ] Atriplex L. ( A. halimus L., A. littoralis L., and A. patula L.), Halimione Aellen ( H. portulacoides (L.) Aellen (recorded as A. portulacoides L.)), Chenopodium L., and Suaeda Scop. ( S. maritima (L.) Dumort.) ( Baldizzone 1979a; Falkovitsh 2006; Baldizzone 2019).

Distribution. Almost all of Europe, Ukraine, Caucasus, Russia (Southern European part, Far East), China, Japan, Korea ( Baldizzone et al. 2006; Kim & Park 2009; Park 2014; Anikin 2019; Baldizzone 2019).

Remarks. The species was first reported from Korea by Baldizzone & Savenkov (2002).

The p-distance, based on GenBank data [accession nos. MT785450.1 (Chinese specimen), HM874720.1, HM874721.1, HM875714.1, HM875725.1 (all Finnish specimens)], ranges from 0–0.9%, within the species (The p-distance between Finnish populations only is 0–0.1%). Considering this, there are two morphological types of the juxtal rods of the phallotheca. The well-known type features two juxtal rods, one thick with a ventral triangular tooth at the apical part, and the other thinner with a pointed apex without any teeth. In the different morphotype observed in illustrations by Kim & Park (2009) and the present study for the Korean specimen, as well as by Li (2012) for the Chinese specimen, the two juxtal rods are symmetrical, with each rod being much slenderer and having a dorsal triangular tooth at the subapical part. The latter type of the juxtal rods similar to that of C. chenopodii Oku, 1965 , as illustrated by Oku (2013: Fig. Col1-15), not by Oku (1965: Pl. XVIII, Fig. E), which was misidentified (see also the remarks on C. chenopodii below).
