Abstract

Two species, Daulia afralis Walker and Herpetogramma cynaralis Walker, belonging to the family Crambidae,Lepdidoptera, are reported for the first time from Korea, based on the materials collected from Jeju Islands located in the southern partof the Korean peninsula. Both male and female genitalia were dissected and examined. Also, the photos of the external morphology,including the wing patterns, and genitalic characteristics of the two species are taken and redescribed briefly, including distributionalranges and available information. Taxonomic information and synonymies for the species were given and discussed.

 Recently, Bae et al.(2008) reviewed a total of 349 species of Pyraloidea of Korea, to revise all the known species in Korea. Also, they enumerated the Korean species under the superfamily Pyraloidea, which was recently proposed taxonomic status(Minet, 1991). However, the two species, Daulia afralis Walker and Herpetogramma cynaralis Walker were not included in them(Bae et al., 2008), which are reported in this study.

 In this study, we report the two newly recorded species of Crambidae, including two females of Daulia afralis Walker and one female of Herpetogramma from Jeju islands located in the southern Korea. Also the genus Daulia is recorded for the first time from Korea.

Materials and Methods

 Materials examined in this study were collected from Jeju Island, southern part of the Korean peninsula and are deposited at the entomological collection of Hannam University (HUNHM). Among them, three specimens of Daulia afralis Walker were loaned to compare with Korean specimens from University of Osaka Prefecture, Osaka, Japan(UOP). All available genitalia were mounted on slide glass with Euparal mountant. The illustrations for each species were taken by digital camera, Nikon attached on the microscope, Carl Zeiss Axio Imager A1. The color standard for the description of adults was based on “Methuen Handbook of Colour” (Kornerup and Wanscher, 1978). Abbreviations used in this study are as follows: gen. sl. no.: genitalia slide number; TS: type species.

 Genus Daulia was established by Walker (1859), based on Daulia afralis Walker (= Girtexa argentuosalis Hampson). In adult, its head and vertex is covered with light brownish yellow scales. The costa of forewing is straight with slightly arched area near costa. It is rather characteristic in having a group of metallic spots near the dorsum of forewing. It is distributed in the Oriental region, including Southeast.

Remarks. Nye & Fletcher (1991) stated “Daulia established in the Pyralidae; it was used for a new species Daulia treicleiota Bethune-Baker, 1911, Ann. Mag. Nat. Hist. (8)8: 544, placed in the Tineidae but currently placed in the Cossidae. Daulia and D. indecora were transferred to the Tineidae by Becker & Robinson, 1981, Syst. Ent. 6: 144”. (Nye and Fletcher, 1991). However, the genus was later placed under the subfamily Pyraustinae of family Pyralidae (Inoue, 1982). Recently the subfamily Pyraustinae was treated as member of the family Crambidae (Munroe and Solis, 1999).

Discussion

 In this study, two species of Crambidae, Daulia afralis Walker and Herpetogramma cynaralis Walker, are reported for the first time from Korea. Among them, Daulia afralis Walker has been known from Southeast Asia, including southern area of Japan and China. And Herpetogramma cynaralis Walker is distributed from southern area of Japan to Australia. In this study, the two species were collected from Jeju, southern area of the Korean peninsula. It can be expected that the species will be used as indicator species for monitoring the climate change for the time being.
