Introduction (Daniel, 1951), Siccia punctata (Fang, 2000), and Siccia sordida (Butler, 1877). The tribe Lithosiini belongs to the subfamily Arctiinae, and in- In this paper, we deal with the genus Siccia that is newly cludes more than 3,445 species of 457 genera distributed worldwide recorded in Korea, with one species, S. obscura (Leech, 1889), being (Heppner 1991; Scoble 1995; Scott et al 2014). This tribe is cosmo- recorded for the first time in Asia. Following this finding, 38 species politan in distribution. Lithosiini can be distinguished from other of 21 genera belonging to the tribe Lithosiini (Erebidae, Arctiinae) Arctiid tribes by the following characteristics: small to medium size are now known to be distributed in Korea (Bae et al 2013; adults, small and slender body, narrow wings; male genitalia with Bayarsaikhan et al 2016). sickle-shaped uncus and well-developed saccular process; female genitalia with very variable sclerotized corpus bursae. Materials and methods The genus Siccia was established by Walker (1854), with the type species Siccia caffra Walker, from South Africa (Cape Colony, Morphologies of the adult and genitalia are studied, and adult Knysna). So far, four species of this genus have been reported from imago and genitalia are illustrated. The specimens used in this Japan (Kishida 2011): Siccia obscura (Leech, 1889), Siccia minuta study are deposited in the collection of Incheon National University, (Butler, 1881), Siccia shikatai (Kishida, 2010), and Siccia kimurai South Korea (INU), and Tokyo, Japan (J-INU).
