In Korea, 104 species of Notodontidae have been recorded. The genus Odontosia Hubner is characterized by the elongate and serrate margin of its forewing and the prominent harpe of valva and many spinular cornuti on the vesica of the male genitalia and the robust ductus bursae and large, ovate and sclerotized corpus bursae of the female genitalia. Only one species of Odontosia, O. patricia Stichel, 1918, has been reported from Korea. In this paper, Odontosia sieversii (Menetries, 1856) is newly added to the Korean fauna based on three male specimens collected at Mt. Bangtaesan, Gangwon-do, Korea. Diagnosis for the species and photographs of adult and genitalia of the genus Odontosia are provided.
Moths of Notodontidae are medium to large-sized moths, comprising approximately 2,500-3,000 species worldwide (Scoble, 1992). They can be easily recognized by the large and triangular forewing with a large prominent “tooth” on the posterior margin and long abdomen. This prominent “tooth” of the forewing produces a tuft that breaks the insect’s outline and aids crypsis while the moth is at rest (Miller, 1991; Park and Kwon, 2001). The monophyly of the Notodontidae is well supported by the serrated edges on the tips of the tibial spurs and a teardrop-shaped, swollen area (bulla) of the metascutal region above the tympanum (Miller, 1991; Scoble, 1992). In larvae, two MD setae on A1, seta X in the anterolateral corner of the anal shield, one SV seta on T2 and T3, a smooth mandibular cutting edge of the late instar larvae, the dorsoventrally compressed and bifid adenosma, and the highly modified anal prolegs that often with eversible distal glands are common characteristics of notodontid larvae (Kitching and Rawlins, 1999).
In Korea, 104 species of Notodontidae have been recorded (Park and Kwon, 2011). The genus
Order Lepidoptera Linnaeus, 1758
Family Notodontidae, Stephens, 1829
Genus Odontosia Hubner, 1819
Odontosia Hubner, 1819: 145. Type species: Phalaena carmelita Esper, 1799.
Diagnosis. The members of the genus can be distinguished by the bipectinate male antennae, short labial palpi, vestigial
proboscis, thorax with dense woolly hair and scales, and elongate wings with thinly scaled forewing with strongly serrate margin. They are similar to those of

Diagnosis. This species (wingspan 35-38 mm) can be distinguished by the larger wingspan, the shortly bipectinate male antennae, short labial palpi, long and brown hairy thorax and legs, and the dorsally shrunk central fascia with dentate postmedial line of dark brownish forewing. This species is externally similar to

Remarks. Schintlmeister (2008) noted the presence of this species in Korea without any detailed information. He included Heilongjiang of northeastern China and Russian Far East in the distribution map of this species, except the Korean peninsula. Park and Kwon (2011) did not include
