19. Coleophora juncivora Baldizzone & Oku, 1990

(Korean name: gob-pul-tong-na-bang)

Coleophora juncivora Baldizzone & Oku, 1990b: 159 . Type locality: Japan, Honshu , Iwate // [holotype (male) deposited in EIHU].

Coleophora juncivora ; Park & Baldizzone 1992: 522; Baldizzone et al. 2006: 70; Kim & Park 2009: 189; Oku 2013: 245; Kim et al. 2013b: 325; Park 2014: 41.

Diagnosis. The species exhibits peculiar genital characteristics, such as the transtilla separated into two strongly curved robust lobes, sinuous juxtal rods of the phallotheca in the male genitalia, and the ductus bursae with a bulged convolution featuring darkened internal grains near the middle, and the corpus bursae with two signa, one mulberry-like and the other leaf-like in the female genitalia. However, it appears to be related to C. alticolella Zeller, 1849 and C. glaucicolella Wood, 1892 , sharing similar external and genital characteristics, as well as a tubular silken larval case and a feeding habit on Juncus seeds, belonging to the family Juncaceae . Nonetheless, it can be distinguished from the latter by the following genital characteristics: 1) in the male genitalia of C. juncivora (see Baldizzone & Oku 1990b: Figs 10 , 11 ), the transtilla divided into two strongly curved lobes, a rhomboid sacculus featuring a rough distal margin and two triangular teeth, one right before the dorsal corner and the other remotely below foregoing one, sinuous two juxtal rods, longer one with a bifurcated dorsal tooth right before the apex, and the other with a triangular dorsal tooth right before the apex, and strong thorn-like cornuti forming a compact row are present, while in C. alticolella (see Baldizzone 2019: Pl. GM LI, Fig. 163), male genitalia possess the transtilla divided into two spatulate lobes, a rhomboid sacculus featuring a rough distal margin in the ventral half and gradually much dentate towards the dorsal corner, much stout and straight juxtal rods, one with a large triangular dorsal tooth at the subapex, and with a small ventral tooth right before the apex, and the other with a small ventral tooth right before the apex, and two groups of cornuti, one forming a claw formation encompassing 5–6 cornuti, and the other arranging in a row comprising 3–4 conical cornuti having broad base, and in C. glaucicolella (see Baldizzone 2019: Pl. GM L, Fig. 160), male genitalia possess the transtilla divided into two slightly curved lobes, a rhomboid sacculus featuring a near-straight distal margin and a robust thorn-like process at the dorsal corner, near symmetrical and weakly bent two juxtal rods, each of them with a triangular ventral tooth at the subapical portion, and two groups of cornuti, one forming a clow formation comprising about 6 cornuti, and the other arranging in a row encompassing 3 conical cornuti; 2) in the female genitalia of C. juncivora (see Baldizzone & Oku 1990b: Figs 13–15 ), the sterigma with a U-shaped concavity at the middle of the posterior margin, the colliculum featuring a sclerotized posterior half and a semitransparent circular anterior half, a wide ductus bursae until a bulged and densely dotted medial convolution, then rapidly narrowed anteriorly, a short spinulate section in about posterior 1/10–1/7 of the ductus bursae, and the corpus bursae with two signa, one mulberry-like and the other leaf-like, are present, while in C. alticolella (see Baldizzone 2019: Pl. GF LV, Fig. 164), female genitalia possess the sterigma with a weak emargination medially at the posterior margin, the colliculum featuring a sclerotized posterior margin and a circular and semitransparent anterior part, an evenly wide ductus bursae featuring a short spinulate section in the posterior 1/5 and a sclerotized and dentate linear plate in the middle portion, and the corpus bursae with a large leaf-like signum, and in C. glaucicolella (see Baldizzone 2019: Pl. GF LIV, Fig. 161), female genitalia possess the sterigma with a weak emargination medially at the posterior margin, a slenderer semitransparent colliculum, the ductus bursae featuring a much longer spinulate section in about posterior 1/4 and a dotted and weakly sclerotized part at the anterior 1/4, and the corpus bursae with a large leaf-like signum.

Adult: ( Baldizzone & Oku 1990b: wingspan 9.5–10.5 mm; Oku 2013: wingspan 9.5–10.5 mm). See Kim & Park (2009: Fig. 12 ); Oku (2013: Fig. 3 -31-35); Park (2014: Pl. for adults, Fig. 15 ).

Male genitalia: See Baldizzone & Oku (1990b: Figs 10 , 11 ).

Female genitalia: See Baldizzone & Oku (1990b: Figs 13–15 : paratype / gen. slide no. Bldz-8338); Park & Baldizzone (1992: Figs 20, 20c ); Kim & Park (2009: Fig. 57); Park (2014: Fig. 15 ).

Larval case (seed miner): Tubular silken case (trivalved). See Baldizzone & Oku (1990b: Figs 8 , 9 ).

Host plants. [ Juncaceae ] Juncus krameri Franch. & Sav. and J. prismatocarpus subsp. leschenaultii (Gay ex Laharpe) Kirschner (recorded as J. leschenaultii J. Gay ex Laharpe ) ( Falkovitsh 2006; Oku 2013).

Distribution. Japan, Korea ( Baldizzone et al. 2006; Kim & Park 2009; Park 2014).

Remarks. The species was first reported from Korea by Park & Baldizzone (1992).
