Diagnosis. The species is slightly similar superficially to C. moehringiae Burmann, 1967, C. salicorniae Heinemann & Wocke, 1876 and C. unipunctella Zeller, 1849 in that there are similarly situated one or two spots on the forewing, but it is clearly distinguished by the following characteristics (the last species is smaller in size with a wingspan of about 10.0–12.0 mm (Baldizzone 2019)): 1) in the male genitalia of C. serinipennella, they have a depressed globular gnathos knob (2.1× wider than vertical length), a digitiform cucullus, a subtrapezoidal valvula with a conspicuous thick seta on the dorso-distal corner, a prolonged sacculus without any teeth or spines, and a conical phallotheca, while in C. moehringiae (see Baldizzone 2019: Pl. GM XX, Fig. 65) they have a relatively shorter cucullus, the valvula without the thick seta, the dorso-distal corner of sacculus extended into a small pointed triangular shape and in C. salicorniae (see Baldizzone 2019: Pl. GM LXXXVI, Fig. 271) and C. unipunctella (see Baldizzone 2019: Pl. GM LXXXVI, Fig. 272) they have a much smaller and narrower gnathos knob, a completely different shape of sacculus with one and two spines respectively, and the phallotheca with two juxtal rods, and in addition, the genitalia of C. unipunctella have a distinctly broader cucullus; and 2) in the female genitalia of C. serinipennella, they have elongated ovoidal papillae analis, a trapezoidal sterigma, a finely dotted ductus bursae without a spinous zone, the ductus seminalis arising from near the posterior end of the ductus bursae, and a lunate leaf-shaped signum, while in C. moehringiae (see Baldizzone 2019: Pl. GF XXII, Fig. 66) they have the ductus bursae having a spinous zone in the posterior portion, and the ductus seminalis arising from the anterior portion of ductus bursae where it is dotted, in C. salicorniae (see Baldizzone 2019: Pl. GF LXXXIX, Fig. 267) they have pointed and sclerotized papillae analis, a heavily sclerotized sterigma laterally, the ductus bursae having a spinous zone in the posterior portion, the ductus seminalis arising from a dotted area which is in the anterior portion of the ductus bursae, and a transversely elliptic leaf-shaped signum with two marks, and in C. unipunctella (see Baldizzone 2019: Pl. GF XC, Fig. 268) they have the sterigma with a heavily sclerotized transverse line on the sides of the ostium bursae, the ductus bursae with a spinous zone on the posterior portion, the ductus seminalis arising from the central portion of the ductus bursae where it is thickly dotted, and a transversely elliptic leaf-shaped signum with two marks.

Corpus bursae about 0.4× shorter than length of ductus bursae, sac-shaped; signum lunate leaf-shaped, with a curved peduncle; peduncle of signum notched along edge of inner curve.
Host plants. All Chenopodiaceae (Baldizzone 1996; Oku 2013).
Biology. The species is a stem miner of various plants belonging to the family Chenopodiaceae, and the damaged part of the host plants thickens and becomes a gall (Common 1990; Baldizzone 1996; Falkovitsh 2004; Oku 2013).
Distribution. Portugal, Spain, Southern France, Italy, Sicily, Slovenia, Bulgaria, Romania, Greece, Ukraine, Libya, Algeria, Tunisia, Egypt, Palestine, Central Asia, Russia, Australia, Japan (Baldizzone 1996, 2019; Baldizzone et al. 2006; Oku 2013), Korea (new record).
Remarks. Forewing pattern (such as the sharpness of venous lines of the forewing, the number of dots or the presence or absence of dots) and abdominal structures (such as the sharpness of posterior lateral struts) are variable (see the description above), and among the specimens examined, one female (Fig. 1C, specimen accession no. CBNUPM000028) has a noticeably smaller size than the other specimens included in this study or those collected from other countries.
