ABSTRACT

Two species of Cryptophlebia: C. nota Kawabe and C. ombrodelta (Lower), are reported from Korea for the first time. This is in fact the first record of Cryptophlebia from Korea, as the previous Korean records of the genus were based on one species, Cryptophlebia hematoma Diakonoff, currently assigned to Thaumatotibia Zacher. Photos of the superficial and genital features are provided for the two Korean species of Cryptophlebia and their distribution and host are summarized. is recognized as an adventive species in Korea and a potential pest on leguminoseous crops. Keywords: Cryptophlebia, Korea, new records, , Tortricidae

INTRODUCTION This species was later combined to Thaumatotibia (Komai, 1999). Therefore, the present study is in fact the first record Cryptophlebia Walsingham comprises about 53 species pre- of Cryptophlebia from Korea. We report two species of dominantly distributing in the Indo-Pacific Region (Komai, Cryptophlebia new to Korea. All the specimens examined 2013). Obraztsov (1958) proposed that Cryptophlebia be- for this study are deposited at the Department of Plant Med- longs to olethreutine tribe, Grapholitini. Differing from this, icine, Chungbuk National University (CBNU); the National Common (1990) mentioned its relatedness with Microcors- Institute of Biological Resource, Incheon (NIBR); and the ini or Olethreutini, while Horak and Brown (1991) assigned second author’s private collection (KSS). the genus to Eucosmini. Recent phylogenetic approaches with morphologies (Komai, 1999) or molecular data (Regier et al., 2012) supported Obraztsov’s proposal. Komai (1999) SYSTEMATIC ACCOUNTS further suggested that the genus Cryptophlebia belongs to the Grapholita-genus group. Kuznetzov and Stekolnikov in Family Tortricidae Kuznetzov (2005) established Cryptophlebiina, a new sub- Subfamily tribe within Grapholitini, for Cryptophlebia and Thaumato- Tribe Grapholitini tibia Zacher.
