Diagnosis. The species is externally similar to C. caespititiella Zeller, 1839 , including male genitalia characters, albeit with some differences. However, it can be clearly distinguished from the latter by the female genitalia: 1) in the male genitalia of C. adjunctella (see Baldizzone 2019: Pl. GM XLIX, Fig. 157), male genitalia possess the sacculus with a blunt distal end, and with a small thorn-like process at the dorso-subdistal margin, and a triangular apical tooth dorsally on each of the two juxtal rods is present, while in C. caespititiella (see Baldizzone 2019: Pl. GM XLIX, Fig. 158), male genitalia possess the sacculus with two subtriangular teeth at the ventro-distal margin, and 5–7 triangular teeth forming a row dorsally on each of the two juxtal rods; 2) in the female genitalia of C. adjunctella (see Baldizzone 2019: Pl. GF LIII, Fig. 158) a subtrapezoidal sterigma surrounding the ostium bursae situated at the middle part of the sternite VII, a cylindrical colliculum, a widened ductus bursae, and a leaf-shaped signum are present, while in C. caespititiella (see Baldizzone 2019: Pl. GF LIII, Fig. 159), female genitalia possess a rectangular sterigma with the ostium bursae situated at the posterior end, an elongated funnel-shaped colliculum with a slightly curved anteriorly at the 1/4, a much slenderer ductus bursae, and a much smaller signum.

Additionally, C. adjunctella exhibits some similarity with C. lassella Staudinger, 1859 in the female genitalia, sharing the characters such as an elongated papillae anales, a subtrapezoidal sterigma with a medial concavity at the posterior end, an elongated colliculum, a rather short spinulate section of ductus bursae, and a large leaf-like signum, but can be easily distinguished by the following characteristics: 1) the adult of C. adjunctella (see Baldizzone 2019: Pl. AD XXX, Fig. 164) has the forewings are brownish-orange or greyish-brown with a yellowish-white costa covering the basal 2/3, while C. lassella (see Baldizzone 2019: Pl. AD XXXI, Fig. 173) has the forewings are greyish-brown with a white costa covering basal 5/8 and whitish venous lines; 2) in the male genitalia of C. adjunctella , male genitalia possess a subtriangular sacculus with a small thorn-like dorsal process, while in C. lassella (see Baldizzone 2019: Pl. GM LII, Fig. 166), the sacculus is trapezoidal with a much longer finger-like dorsal process; 3) in the female genitalia of C. adjunctella , the colliculum is cylindrical, about 1.2–1.7× longer than the length of the sterigma, without twist, while in C. lassella (see Baldizzone 2019: Pl. GF LVI, Fig. 167), female genitalia possess the colliculum that gradually broadens beyond a twist which is situated at the posterior 2/5, about 2.3–2.7× longer than the length of the sterigma.

Adult: ( Benander 1939: wingspan 9.0–10.0 mm; Toll 1953: wingspan 10.0–12.0 mm; Baldizzone 2019: wingspan 8.0–11.0 mm). See Kim et al. (2013b: Fig. 1 ); Park (2014: Pl. for adults, Fig. 1 ); Baldizzone (2019: Pl. AD XXX, Fig. 164).

Male genitalia: See Benander (1939: Pl. III, Fig. 54); Toll (1953: Fig. 106); Patzak (1974: Fig. 188); Baldizzone (2019: Pl. GM XLIX, Fig. 157).

Female genitalia: See Benander (1939: Pl. VII, Fig. 94); Toll (1953: Fig. 263); Patzak (1974: Fig. 314); Kim et al. (2013b: Figs 5, 5a ); Park (2014: Fig. 1 ); Baldizzone (2019: Pl. GF LIII, Fig. 158).

Larval case (seed miner): Seed case. See Benander (1939: Pl. VIII, Fig. 14 ); Toll (1962: Pl. 27 S, Fig. 253); Baldizzone (2019: Pl. AST XXI, Fig. 146).

Host plants. [ Juncaceae ] Juncus compressus Jacq. and J. gerardii Loisel. ( Falkovitsh 2006; Baldizzone 2019).

Distribution. Northern and Central Europe, Belgium, France, Italy, Romania, Ukraine, Russia (European part, Western Siberia, Far East), Turkey, Turkmenistan, Iran, Afghanistan ( Baldizzone et al. 2006; Anikin 2019; Baldizzone 2019), Japan, Korea ( Kim et al. 2013b; Park 2014).

Remarks. The species was first reported from Korea by Kim et al. (2013b).
