Four species of Bucculatrix (Lepidoptera: Bucculatricidae) new to Korea

Bucculatrix Zeller, 1839 is a large group of leaf-miners in Bucculatricidae. The genus shows worldwide distribution with about 300 species, but taxonomic study has been rather limited in Korea. In this paper, we report four species of Bucculatrix for the first time in Korea: B. altera Seksjaeva, 1989, B. bisucla Seksjaeva, 1989, B. demaryella (Duponchel 1840) and B. tsurubamella Kobayashi, Hirowatari & Kuroko, 2010. Diagnoses, redescriptions, photographs of adults and genitalia, and DNA barcodes of each species are provided.
