Abstract

In a faunal survey of the Gelechiidae (Lepidoptera: Gelechioidea) from Is. Ulleung-do in the East Sea of Republic of Korea, one species of Gelechiidae, Bagdadia gnomia Ponomaranko, is reported for the first time from Korea and an unknown species of the genus Bryotropa was discovered. In addition, eight species of Gelechiidae including a little known species, Dichomeris anisacuminata Li & Zheng, were first recorded from Is. Ulleung-do. Images of adults and genitalia for the newly recorded species and a little known species are provided.

    Ministry of Environment

    Is. Ulleung-do is located about 270 km east from Phohang in the East Sea, more than three and half hours by express passenger ship. The island is 72.56 km2 width with a population of less than 13,000 residents. Mt. Seonginbong (ca. 984 m) is the highest with a broad basin called Naribunji which is 1.5-2.0 km2 width and located at 860m above sea level in the middle of the island. There are two crater basins with two villages: Narimaeul in the North and Albongmaeul in the Southwest (Park, 1997). Only few insect surveys have been conducted due to a long distance from the Korean Peninsula and an inconvenient approach.

    The first fauna survey on Lepidoptera in Is. Ulleung-do was conducted by Cho (1955), who first reported five species of moths and 26 species of butterflies, and later (1965) listed 267 species of moths and 83 species of butterflies. Recently Byun et al. (1996) reported 137 species of 24 families with 43 additional species for the fauna of Is. Ulleung-do, but no species of family Gelechiidae has been known from the island to date. The family Gelechiidae is one of the largest and least known families of micromoths, comprising more than 4,700 known species belonging to about 500 genera in the world. The family contains a total of 172 species in the Peninsula (Park and Ponomarenko, 2007; Byun et al. 2009).

    Of the eight known species of Gelechiidae in this study, Anarsia ulneungensis Park & Ponomarenko which is still known as endemic to Korea, and a little known species, Dichomeris anisacuminata Li & Zheng are illustrated. Fig. 1.

    Materials and methods

    This study is based on specimens collected from the Naribunji of Is. Ulleung-do, during June in 2006 by light traps using a Mercury vapor-lamp of 220 V/200 W, and deposited in the Korea National Arboretum (KNA), Pocheon, Korea. The wingspan is measured from the left apex to the right apex of the forewing. For morphological studies, external structures and genital characters were examined under a stereo microscope (Olympus SZ51; Olympus, Japan). A Canon 500D camera (Canon, Japan) was used for the digital photography. The color standard for the description of adults follows Kornerup and Wanscher (1978).

    Results

    Bagdadia gnomia Ponomarenko (Figs. 2, 3, 3a, 3b)

    Bagdadia gnomia:

    Ponomarenko, 1995. Actias, 2: 50. TL: Primorye, Russian Far East.

    Capidentalia gnomia:

    Ponomarenko, 1997: 49; 1999: 254.

    Bagdadia gnomia:

    Sattler, 1999: 238; Park & Ponomarenko, 2007: 179.

    Diagnosis:

    Male genitalia (Figs. 3, 3a-b). Bagdadia gnomia is differed from B. claviformis (Park, 1983) by the male genital characters: 1) cucullus with dilated part beyond distal 3/4 length; 2) valvella stout, bifurcated apically.

    Material examined.

    4♂, Is. Ulleung-do, Naribunji, 19-20. vi. 2006 (MY Kim & MY Chae), gen. slide no. KNA-3161, KNA-3163.

    Distribution:

    Korea (new record), Russian Far East (Primorye), Japan.

    Remarks:

    The genus Bagdadia Amsel was originally placed in family Scythrididae by Rebel (1901), and later transferred to family Gelechiidae by Sattler (1973). The genus mostly occurs in East Asia: two species in the Russian Far East, four species in China, and two species in Korea. The male genitalia is characterized by having a crown-shaped uncus and elongate valva.

    Bryotropha sp. (Figs. 4, 5, 5a, 5b)

    Diagnosis:

    The female genitalia (Figs. 5, 5a-b) are characterized by the large signum with short posterior spine laterally and a long anterior process serrated along lateral margins. Only one female was available to be examined. The species is probably an undescribed and will be described when additional material is available.

    Material examined:

    1♀, Is. Ulleung-do, Naribunji, 19-20. vi. 2006 (MY Kim & MY Chae), gen. slide no. KNA-3167.

    Distribution:

    Korea (new record).
