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 plants are summarized. Cryptophlebia ombrodelta is recognized as an adventive species in Korea and a potential pest on leguminoseous crops.

INTRODUCTION
Cryptophlebia Walsingham comprises about 53 species predominantly distributing in the Indo-Pacific Region (Komai, 2013) . Obraztsov (1958) proposed that Cryptophlebia belongs to olethreutine tribe, Grapholitini. Differing from this, Common (1990) mentioned its relatedness with Microcorsini or Olethreutini, while Horak and Brown (1991) assigned the genus to Eucosmini. Recent phylogenetic approaches with morphologies (Komai, 1999) or molecular data (Regier et al., 2012) supported Obraztsov’s proposal. Komai (1999) further suggested that the genus Cryptophlebia belongs to the Grapholita- genus group. Kuznetzov and Stekolnikov in Kuznetzov (2005) established Cryptophlebiina, a new subtribe within Grapholitini, for Cryptophlebia and Thaumatotibia Zacher. Cryptophlebia includes medium-sized to large moths typically with a subtriangular pretornal patch on the forewing. The larvae often bore into fruits, galls or twigs of various host plants, mainly Leguminosae. A polyphagous species, Cryptophlebia ombrodelta (Lower), also known as the macadamia nut borer, is a serious pest of macadamia (Proteaceae) and lychee (Sapindaceae) (Common, 1990) .
The first Korean record of Cryptophlebia was given by Byun et al. (1998) with Cryptophlebia hemitoma Diakonoff. This species was later combined to Thaumatotibia (Komai, 1999) . Therefore, the present study is in fact the first record of Cryptophlebia from Korea. We report two species of Cryptophlebia new to Korea. All the specimens examined for this study are deposited at the Department of Plant Medicine, Chungbuk National University (CBNU); the National Institute of Biological Resource, Incheon (NIBR); and the second author’s private collection (KSS).

Diagnosis. Cryptophlebia is closely related to Thaumatotibia but differs from the latter in having a subtriangular or Y-shaped plate on the male tergum VIII (a broad plate in Thaumatotibia ) and a pair of filiform scale-tufts on each side from the pocket on each side of male tergum VIII (absent in Thaumatotibia ). Komai (1999) recognized three additional character states supporting the monophyly of Cryptophlebia : (1) male sternum VIII with a pair of short projections laterally; (2) a greatly swollen, clavate valva with sparse strong spines on the inner surface of the cucullus; and (3) the corpus bursae spinulose in anterior 1/2-4/5. The males usually have the hind-tibia and first hind-tarsomere short and wide, with piliform scale, the hindwing on the underside usually with an elongate, heavily sclerotized pocket formed in the distal half of CuA 2 which contains a mass of fine piliform scales (Komai, 1999) .
Distribution. Worldwide except for the Nearctic region, most diverse in Indo-Pacific area.
Host plants. Seeds, nuts, pods, fruits, or twigs of various plant families including Anacardiaceae, Hippocastanaceae, Leguminosae, Proteaceae, Rhizophoraceae, Rutaceae, and Sapindaceae (Komai, 1999) .

Distribution. Korea (new record), Japan, Russia (Far East), China, Taiwan, Southeast Asia, India, Sri Lanka, Guam Island, Australia, New Guinea, Fiji, and Hawaii Islands.
Host plant. This species is one of the well-known pests to macadamia nuts (Proteaceae: Macadamia spp.), therefore known as the macadamia nut borer. Another vernacular name of this species is the litchi fruit moth, also reflecting its host plant. The larvae are seed feeders on a wide range of leguminoseous plants, e.g., Acacia , Adenanthera , Bauhinia , Caesalpinia , Cassia , Indigofera , Parkinsonia , Phaseolus , Pithecolobium , Poinciana , Prosopis , Sesbania , and Tamarindus , and also fruit feeders on Arecaceae- Cocos nucifera L.; Euphorbiaceae- Euphorbia ; Polygonaceae- Coccolobis uvifera (L.) Crantz; Rutaceae- Aegle , Citrus , and Feronia ; Saphidaceae- Filicium decipiens Thwaites, Litchi chinensis Sonn. (Bradley, 1953 ; Diakonoff, 1957a ; Issiki, 1957 ; Zimmermann, 1978 ; Komai, 1999 ; Kuznetzov, 2005) .
Remarks. Diakonoff (1957a) suggested that it originated from India. This species seems adventive rather than residential in Korea since it has been caught only from the areas adjacent to the coasts. Once established, this species could be a potential pest on leguminoseous crops.
