The genus Proutia Tutt, 1899 (Lepidoptera, Psychidae) comprises 14 species found throughout the world. In East Asia, three species, Proutia chinensis Hättenschwiler & Chao, 1990, P. maculatella Saigusa & Sugimoto, 2014 and P. nigra Saigusa & Sugimoto, 2014, are known from Korea, Japan and China.
Proutia cornucervae Roh & Lee, sp. nov. is newly recognised from Korea. In addition, Bruandella niphonica (Hori) is transferred to genus Proutia. Male and genitalia of the species are described and DNA barcodes are provided.

The family Psychidae consists of 241 genera with 1,350 described species (
The genus Proutia Tutt, 1899 was based on the type species Psyche betulina Zeller, 1839. Recently, genera Anaproutia Lewin, 1949 and Bruandella Saigusa & Sugimoto, 2014 were synonymised to genus Proutia (
The purpose of this paper is to describe a new species, Proutia cornucervae sp. nov., including the collecting localities, illustrations of male adult and genitalia and DNA barcode. In addition, Bruandella niphonica (Hori, 1926) is transferred to genus Proutia. Furthermore, DNA barcodes for precise identification of five species of Korean Proutia (four) and Psyche (one) are also provided.
The materials examined in this study are kept in the Entomological Collection, Honam National Institute of Biological Resources (ECHNIBR), Mokpo, Korea. The male genitalia were dissected and examined after mounting on glass slides in 80% glycerol solution. The wing venations were examined in 70% alcohol solution. Photographs of adults were taken using a MP-E 65 mm f/2.8 1-5x Macro Photo, attached to 5D Mark IV digital camera (Canon, Tokyo, Japan). Photographs of the male genitalia was taken using a DFC 95 mm digital camera (Leica, Wetzlar, Germany) attached to a Leica M205A stereomicroscope (Leica, Wetzlar, Germany). Terminology and morphological characters of the adult, wing venation and genitalia follow
Genomic DNA from seven specimens of Proutia maculatella, four specimens of P. nigra, nine specimens of P. niphonica, one specimen P. cornucervae sp. nov. and one specimen of Psyche yeongwolensis was extracted from the legs of dried specimens of adults in 100% alcohol using a Genomic Cell/Tissue Spin Mini Kit (Qiagen, Inc, Hilden, Germany), according to the manufacturer’s protocol. Specimens were sequenced and the DNA barcode, cytochrome oxidase subunit I gene (COI), was amplified using the primers LCO1490 and HCO2198 (

* In this study
The barcodes were compared to 50 DNA barcodes of the genera Proutia and Psyche downloaded from NCBI (https://www.ncbi.nlm.nih.gov/) and BOLD systems (https://v4.boldsystems.org/) (Table
Adult (Fig.
This species is similar to P. nigra Saigusa and Sugimoto, but can be distinguished by the much darker wings being blackish-brown and pectinations of the antennae elongate and about about same length from basal flagellomeres to flagellomere 9. Whereas in P. nigra, the wings are slightly lighter, being brownish-black and pectinations of antennae abruptly becoming longer to 7th flagellomere.
The specific name is derived from the Latin cornu and cerva (= antler), referring to the antennae shape.
Korea (new species).
Eumea niphonica Hori, 1926: 28 (Eumea is misspelling of Fumea). Type locality: Japan.
Psyche casta (Pallas, 1767):
Bruandia niphonica (Hori, 1926):
Bruandella niphonica (Hori, 1926):
The placement of niphonica Hori, 1926 has been a debatable issue. The species was described by Hori, based on specimens collected from Honshu and Kiyshu in Japan and assigned to Eumea, an incorrect subsequent spelling of Fumea Haworth, 1812.

A total of 22 new sequences was generated from four species of Proutia and one species of Psyche (567–658 bp of partial COI). All new sequences were deposited in GenBank (accession numbers: MT154331–154332, OR122630–122634 and OR134240–134253 in Table
Genetic divergence of COI, using uncorrected p-distances amongst the Proutia and Psyche species, ranged from 5.8% to 16.0% (the result between P. betulina and P. rotunda was excluded, as it was considered to be due to misidentification), while intraspecific divergence ranged from 0% to 3.6% (Table
