Koo, Jun-Mo & Cho, Soowon, 2024, Taxonomic revision of the family Coleophoridae (Lepidoptera: Gelechioidea) in Korea, including seven newly recorded species of the genus Coleophora Hübner, Zootaxa 5558 (1), pp. 1-102 : 72

33. Coleophora rectimarginalis Li, 2004

(Korean name: u-po-tong-na-bang)

Coleophora rectimarginalis Li, 2004: 320 . Type locality: China, Heilongjiang, Harbin // [holotype (male) deposited in NKU]. Ecebalia rectimarginalis ; Anikin 2019: 80.

Coleophora rectimarginalis ; Baldizzone et al. 2006: 100; Kim & Park 2009: 191; Park 2014: 54.

Diagnosis. The species is similar to C. sittella Baldizzone, 1989 , but it can be distinguished from the latter by the male genitalia: in C. rectimarginalis (see Li 2004: Figs 27–29 ), the sacculus with a triangular ventral expansion, two juxtal rods much slenderer and longer, one featuring a small thorn-like dorsal process at the subapical part, and the other featuring a long thorn-like dorsal process at the basal 1/5 and a triangular ventral tooth at the distal 3/5 and a long and curved cornutus are present, while in C. sittella (see Baldizzone 1989b: Figs 86, 88, 89), male genitalia possess the sacculus without a triangular ventral expansion, thicker and shorter two juxtal rods, one featuring a triangular dorsal tooth at the subapical part, and the other featuring a thorn-like dorsal process at the middle, and cornuti forming a curved linear formation.

Adult: ( Li 2004: wingspan 10.5–12.5 mm). See Li (2004: Fig. 6 ); Kim & Park (2009: Fig. 18 ); Park (2014: Pl. for adults, Fig. 23 ).

Male genitalia: See Li (2004: Figs 27–29 ); Kim & Park (2009: Figs 41, 41a); Park (2014: Fig. 23 ).

Female genitalia: See Li (2004: Fig. 10 ).

Larval case: Unknown.

Host plants. Unknown.

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

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