Abstract
A new species, Homidia pseudokoreana sp. nov., from South Korea described based on morphological data and DNA barcodes. This species is morphologically characterized by the body color pattern with a longitudinal dark stripe on medial area of Th. II to Th. III, coxal macrochaetal formula as 3/4+1,3/4+2, and unguis III with three inner teeth. In this study, DNA sequences of mitochondrial cytochrome c oxidase subunit I (COI) gene were used as DNA barcode to distinguish species. It showed distinct differences in genetic distances between Homidia species. DNA barcoding was a useful tool when identifying morphologically closely related species in Homidia.
