Introduction

Smaragdina Chevrolat 1837 is a large genus of the tribe Clytrini inthe family Chrysomelidae and is distributed in the Paleoarctic andOriental regions (Chûjô and Kimoto, 1961; Erber and Medvedev,1999; Gök, 2003; Maican, 2005, 2006). In the Paleoarctic region, 175species have been reported. However, 47 were synonymized, result-ing in 128 current species (Löbl and Smetana, 2010). Approximately40 Smaragdina species are distributed throughout northeast Asia,including Korea and Japan (Gressitt and Kimoto, 1961; Kimoto andTakizawa, 1994, 1997). Only five species have been reported inKorea until now (Lee and An, 2001). In this paper, we report Smarag-dina nipponensis (Chûjô) for the first time in Korea. As a result of thisstudy, a total of six species of the genus Smaragdina are now recordedin Korea. We provide a description of the beetle, a modified key to theKorean Smaragdina, photographs of adults, drawings of the aedeagus,and diagnostic characteristics. The specimens examined have beendeposited in the insect collection of the Department of Applied Biolo-gy, Kyungpook National University (Sangju, Korea).

Diagnosis. Head entirely yellowish brown and punctures ofpronotum finer, usually covering basal area only; elytron minutelyand irregularly punctuate; antenna with third segment distinctlyshorter than second segment (Fig. 1d); scutellum narrowly truncatedat apex; generally yellowish or reddish brown, antenna black, darkreddish brown with basal three or four segments paler, legs yellowishbrown with tarsi and apical areas of tibiae blackish brown to black(Fig. 2a, b), and entire tibiae black (Fig. 2c); in dark colored speci-mens, meso-metathorax and abdomen entirely blackish (Fig. 3a, b);length 5.2–6.2 mm.

Specimens examined. 50 exs., Heungnae-dong, Suncheon-si,Jeollanam-do, Korea, 15.v.2010, coll. J.Y. Park; 10 exs., Gadeok Island,Soho-dong, Yeosu-si, Jeollanam-do, Korea, 22.v.2011, coll. J.Y. Park.

Distribution. Korea (new record), Japan, S. China, Taiwan.Host plant. Quercus acutissima Carruthers. Chûjô and Kimoto

(1961) reported Salix gilgiana Seemen as host plant in Japan.Remarks. A Taiwan species, Gynandrophthalma flavimana, was

identified as a new species by Chûjô (1952). Besides this type speci-men, Kimoto (1966) reported that several specimens from Taiwanwere identical to Smaragdina nipponensis (Chûjô) described fromJapan. Gressitt and Kimoto recorded the species from S. China as S.nipponensis in 1961 and corrected it as flavimana in 1963. Color

Fig. 2. Color variations of the legs: (a) tarsi yellowish brown and apical areas of tibia black

variations of the abdomen and legs of the Taiwan specimens led tothe subsequent misidentification, but it was treated as synonym byLöbl and Smetana (2010).
