Coleophora ulmivorella ; Moriuti 1982a: 261; Vives 1988: 124; Baldizzone & Savenkov 2002: 368; Murakami 2002: 36; Baldizzone et al. 2006: 118; Oku 2013: 232.

Diagnosis. The species shares external and genital characteristics with C. alnifoliae Barasch, 1934 . However, it can be distinguished from the latter by the following genital characteristics: 1) in the male genitalia of C. ulmivorella (See Oku 1965: Pl. XVII, Fig. E), an elongated sacculus terminating into a thorn-like process with a narrow and small tooth at the base of the process is present, while in C. alnifoliae ( Baldizzone 2019: Pl. GM V, Fig. 14 ), male genitalia possess an elongated sacculus featuring a rounded apex and a rounded triangular tooth at the base of the process; 2) in the female genitalia of C. ulmivorella ( Oku 1965: Pl. XVIII, Fig. D), the corpus bursae without a leaf-like signum is present, while in C. alnifoliae ( Baldizzone 2019: Pl. GF V, Fig. 15 ), female genitalia possess the corpus bursae with a leaf-like signum.

Adult: ( Oku 1965: wingspan 9.0 mm; Moriuti 1982a: wingspan 9.0 mm; Oku 2013: wingspan 9.0 mm). See Moriuti (1982b: Pl. 12, Fig. 36: paratype); Oku (2013: Fig. 3 -30-12).

Male genitalia: See Oku (1965: Pl. XVII, Fig. E).

Female genitalia: See Oku (1965: Pl. XVIII, Fig. D).

Larval case (leaf miner): Spatulate leaf case (bivalved). See Oku (1965: Pl. XX, Fig. A); Jinbo & Suzuki (2023).

Host plants. [ Ulmaceae ] Ulmus laciniata (Herder) Mayr ex Schwapp. , U. davidiana Planch. ( U. davidiana var. japonica (Rehder) Nakai ), U. parvifolia Jacq. ( Oku 2013) ; and [ Araliaceae ] Kalopanax septemlobus subsp. septemlobus (Thunb.) Koidz. (recorded as K. ricinifolius (Siebold & Zucc.) Miq. ) ( Falkovitsh 2006).

Distribution. Japan ( Baldizzone et al. 2006), Russia (Far East) ( Baldizzone & Savenkov 2002; Kim & Park 2009; Park 2014; Anikin 2019) ( Korea excluded here).

Remarks. According to Kim & Park (2009), the species was first reported from Korea by Baldizzone & Savenkov (2002). However, Korea was listed as part of its distribution without examination of Korean specimens. Although we attempted to trace earlier records that included Korean specimens of this species and the Korean specimens examined and identified as C. ulmivorella by Kim & Park (2009) and Park (2014), we were unsuccessful. In contrast, Oku (2013) documented that the species is exclusively distributed in Japan and Russia.

C. ulmivorella is characterized by yellowish-brown forewings ( Oku 1965: 114; Moriuti 1982b: Pl. 12, Fig. 36), an elongated sacculus terminating into an upturned thorn-like process featuring a narrow and small tooth at its base in the male genitalia ( Oku 1965: Pl. XVII, Fig. E), and the corpus bursae without a leaf-like signum in the female genitalia ( Oku 1965: Pl. XVIII, Fig. D). Despite the poor condition, the Korean specimens illustrated by Kim & Park (2009: Fig. 23 ) and Park (2014: Pl. for adults, Fig. 27 ) differ from C. ulmivorella in greyish-yellow forewings, the sacculus with a much longer ventral process in the male genitalia ( Kim & Park 2009: Figs 45, 45a; Park 2014: Figs 27A, D ), and the corpus bursae featuring a leaf-like signum in the female genitalia ( Kim & Park 2009: Fig. 63; Park 2014: Fig. 27E ). Taking into consideration these differences, we considered the Korean specimens are not conspecific with C. ulmivorella , and therefore, exclude this species from the list of Korean Coleophoridae .

The female genitalia of Korean specimens appear to be more similar to those of C. alnifoliae ( Baldizzone 2019: Pl. GF V, Fig. 15 ) which is distributed in almost all of Europe, Caucasus, central Siberia, China, Canada, and USA, while the male genitalia exhibit a clear difference in the shape of the process on the sacculus compared to that of C. alnifoliae ( Baldizzone 2019: Pl. GM V, Fig. 14 ). Therefore, due to the uncertainty of whether the male and female of the Korean specimens belong to the same species, it is intended to revisit this matter once additional specimens, for which DNA sequencing is possible, become available.
