18. Coleophora japonicella Oku, 1965

(Korean name: neu-leub-tong-na-bang)

Coleophora japonicella Oku, 1965: 115 . Type locality: Japan, Hokkaido, Sapporo // [holotype (male) deposited in EIHU].

Suireia japonicella ; Lelej 2016: 99; Anikin 2019: 73; Anikin 2021: 321.

Coleophora japonicella ; Moriuti 1982a: 261; Vives 1988: 86; Baldizzone & Savenkov 2002: 369; Murakami 2002: 36; Baldizzone et al. 2006: 69; Kim & Park 2009: 189; Oku 2013: 232; Park 2014: 40; Oku & Kusunoki 2018: Fig. 9 .

Diagnosis. The species bears external similarities to its allies, such as C. limosipennella ( Duponchel, 1843) , C. florisigna Li & Zheng, 2000 , C. varilimosipennella Li & Zheng, 2000 , and C. myricae Oku & Kusunoki, 2018 , as well as genital characteristics, including a narrowly elongated sacculus terminating in a slightly upturned thorn-like distal end featuring a small subapical tooth-like process, and a conical phallotheca in the male genitalia, and a division at the posterior margin of the sterigma, connecting with a widely hollowed-out ovaloid sinus vaginalis, and elliptical corpus bursae in the female genitalia. However, the species can be distinguished from the latter by the following genital characteristics: 1) in the male genitalia of C. japonicella (see Oku & Kusunoki 2018: Fig. 9 ), the phallotheca without any cornuti, and a visible annulus are present, while in C. limosipennella (see Baldizzone 2019: Pl. GM VI, Fig. 17 ), male genitalia possess the phallotheca without any cornuti, and an invisible annulus, in C. florisigna (see Li & Zheng 2000a: Figs 2 , 3 ), male genitalia possess the phallotheca with a stout cornutus, and an invisible annulus, in C. varilimosipennella (see Li & Zheng 2000a: Figs 7 , 8 ), male genitalia possess the phallotheca with several small cornuti, and an invisible annulus, and in C. myricae (see Oku & Kusunoki 2018: Fig. 8 ), male genitalia possess the phallotheca with a linear cornutus, and an invisible annulus; 2) in the female genitalia of C. japonicella (see Oku 1965: Pl. XIX, Fig. C), the corpus bursae featuring a leaf-like signum is present, while in C. limosipennella (see Baldizzone 2019: Pl. GF VI, Fig. 18 ), the corpus bursae with a thorn-like signum featuring an irregularly jagged basal portion is present, in C. florisigna (see Li & Zheng 2000a: Fig. 5 ), female genitalia possess the corpus bursae with a mulberry-like signum surrounded by small teeth, in C. varilimosipennella (see Li & Zheng 2000a: Fig. 10 ), female genitalia possess the corpus bursae with a leaf-like signum featuring a compressed basal plate, and in C. myricae (see Oku & Kusunoki 2018: Fig. 16 ), female genitalia possess the corpus bursae with an indented thorn-like signum.

Adult: ( Oku 1965: wingspan 11.0–13.0 mm; Moriuti 1982a: wingspan 10.5–13.0 mm; Oku 2013: wingspan 9.0– 10.5 mm). See Moriuti (1982b: Pl. 12, Fig. 37: paratype); Kim & Park (2009: Fig. 11 ); Oku (2013: Figs 3 -30- 10, 11); Park (2014: Pl. for adults, Fig. 14 ).

Male genitalia: See Oku (1965: Pl. XVII, Fig. F); Oku & Kusunoki (2018: Fig. 9 ).

Female genitalia: See Oku (1965: Pl. XIX, Fig. C); Kim & Park (2009: Fig. 56); Park (2014: Fig. 14 ).

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

Host plants. [ Ulmaceae ] Ulmus davidiana var. japonica (Rehder) Nakai ( Falkovitsh 2006) and U. laciniata (Herder) Mayr ex Schwapp. ( Oku 2013) .

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

Remarks. The species was first reported from Korea by Kim & Park (2009).
