Four Newly Recorded Species of the Family Crambidae (Lepidoptera) from Korea

  • cc icon
  • ABSTRACT

    This study was carried out to report the newly recorded species of the family Crambidae, belonging to the order Lepidoptera. During the course of investigation on the family Crambidae in South Korea, the following four species are reported for the first time from Korea: Diplopseustis perieresalis (Walker, 1859), Dolicharthria bruguieralis (Duponchel, 1833), Herpetogramma ochrimaculale (South, 1901), and Omiodes diemenalis (Guenée, 1854). Among them two genera, Diplopseustis Meyrick and Dolicharthria Stephens, are also newly reported from Korea. External and genital characteristics of adults were examined and illustrated. All of the newly recorded species were enumerated with their available information including the collecting localities, illustrations of adults, and genitalia.

  • INTRODUCTION

    Until now, more than 16,000 species of the superfamily Pyralodiea have been recorded in the world (Munroe and Solis, 1999). In Korea, a total of 349 species of the superfamily Pyralodiea have been known to date (Bae et al., 2008). Later Kim et al. (2012) added two newly recorded species from Korea, Daulia afralis Walker and Herpetogramma cynaralis Walker. Recently, Kim et al. (2014) reviewed the genus Nacoleia, including two new records, N. inouei Yamanaka and N. satsumalis South. Consequently, a total of 353 species has been recorded from Korea to date. During the course of the survey on the microlepidoptera in Korea, we found the following four species of Crambidae: Diplopseustis perieresalis (Walker), Dolicharthria bruguieralis (Duponchel), Herpetogramma ochrimaculale (South), and Omiodes diemenalis (Guenée).

    Thus, the aim of this study is to report four newly recorded species and to update our knowledge with recently collected data on the fauna of Crambidae of Korea. All of the examined materials for each species are enumerated with their localities and available information.

    MATERIALS AND METHODS

    Materials examined in the present study are preserved in the Systematic Entomology Laboratory, Hannam University (SELHNU), Daejeon, Korea. The genitalia of both sexes were dissected and examined after mounting with Euparal mountant for identification of the species. The photos of adults and genitalic structures for the species were taken by a digital camera, Pax cam (PAXcam Microscope Cameras Co., Chicago, IL, USA) attached on the microscope, Carl Zeiss Axio Imager A1 (Carl Zeiss Ltd., Cambridge, UK). Abbreviations used in this study are as follows: TL, type locality; TS, type species; GS, genitalia slide number.

    DISCUSSION

    In this study, four species of Crambidae, Diplopseustis perieresalis (Walker), Dolicharthria bruguieralis (Duponchel), Herpetogramma ochrimaculale (South), and Omiodes diemenalis (Guenée) are reported from Korean peninsula for the first time. The three species among them, with the exception of Herpetogramma ochrimaculale (South), are distributed worldwide including Asia, Europe, Africa, and Australia. In Korea, Diplopseustis perieresalis (Walker) was collected from Is. Geoje which is the southern area of the Korean peninsula. Also, Herpetogramma ochrimaculale (South) was collected from Isl. Ulleung which is the eastern area of the Korean peninsula. These species can be expected to be used as indicator species for the time being to monitor the distributional characteristics.
