Morphological and mitochondrial DNA analyses indicate the presence of a hybrid zone between two species of leaf beetle (Coleoptera; Chrysomelidae) in Southern Spain

The present study reports a case where the survey of morphological and mitochondrial DNA variation among populations of a species complex of leaf beetle, the Gonioctena variabilis complex, has lead to the identification of a hybrid zone between two species of the complex in Southern Spain. The complex is divided into four species distributed around the western Mediterranean region. The four species, G. variabilis, Gonioctena aegrota, Gonioctena gobanzi, and Gonioctena pseudogobanzi, are traditionally determined by differences in the morphology of the male genitalia (aedeagus). To gain insight into the history of the speciation process within this species complex, we sampled populations in Portugal, Spain, Southern France, and Northern Italy. We sequenced a portion of the mitochondrial control region of each individual collected. A haplotype network of these sequences was found to comprise four distinct groups of sequence types, separated by a relatively large number of mutations. Moreover, in most of the samples for which morphological and molecular variation is available, there is a one‐to‐one correspondence between haplotype group, defined by mitochondrial sequence variation, and morphological groups defined on the basis of the aedeagus, showing evidence of four historically independent evolutionary units. This supports the use of the aedeagus morphology as a taxonomically informative trait in this species complex and a recent taxonomic revision upgrading four formerly subspecies, corresponding to the evolutionary units identified in the present study, to species status. However, some of the individuals from our samples in Southern Spain, morphologically identified as G. aegrota, were found to possess mitochondrial sequences typical of G. pseudogobanzi. The opposite case was also found. This suggests the presence of a zone of contact and hybridization between G. aegrota and G. pseudogobanzi. The location of this hybrid zone appears to be unusual. We identify historical scenarios that may explain our observations. © 2008 The Linnean Society of London, Biological Journal of the Linnean Society, 2008, 94 , 105–114.     

A taxonomic review of Korean Hydroglyphus Motschulsky (Coleoptera: Dytiscidae: Hydroporinae) with a description of new species

A key to the Korean species and genera, diagnoses, whole‐body photographs of adults, and illustrations of diagnostic characters are provided.     

Snow craneflies of the Genus Chionea Dalman (Diptera: Limoniidae) from Korea

The Korean snow cranefly genus Chionea Dalman is reviewed taxonomically. Four species are identified: C. crassipes Boheman, C. kanenoi Sasakawa, C. mirabilis Vanin and C. deogyusana sp. nov. Among them, C. deogyusana sp. nov. is new to science, and C. kanenoi is reported for the first time in Korea. A key to Korean species and photographs of external features are given.     

Taxonomic revision of the genus Jassidophaga Aczél (Diptera: Pipunculidae) in Korea

In this paper, three Korean species of the big‐head fly, genus Jassidophaga Aczél were treated: J. chiiensis (Ouchi), J. pala (Morakote) and J. villosa (Roser). Of these, J. pala is reported in Korea for the first time. A key to Korean species and photographs on external features are given.     

Revision of the family Sphecidae (Hymenoptera: Apoidea) in South Korea

Korean species of the family Sphecidae are reviewed, and seventeen species in nine genera belonging to three subfamilies are confirmed. Among them, Ammophila campestris and Sceliphron caementarium are new to South Korea. Korean occurrence of Sceliphron madraspatanum is confirmed with an actual Korean specimen. This paper provides the first determination keys to higher taxa and species occurring in South Korea. Taxonomic information of each species including original publication of valid name and justifiable references for Korean occurrence is provided. Digital images and line drawings for selective characteristics are also available.     

Taxonomy of the genus Atherigona Rondani (Diptera: Muscidae) from Korea

The Korean shoot fly genus Atherigona Rondani is reviewed taxonomically. A total of five species was identified: A. (Acritochaeta) orientalis Schiner, A. (Atherigona) biseta Karl, A. (Atherigona) falcata (Thomson), A. (Atherigona) oryzae Malloch, and A. (Atherigona) bifurca sp. nov. Of these, A. (Atherigona) bifurca sp. nov. is new to science, and A. (Atherigona) biseta Karl and A. (Atherigona) falcata (Thomson) are reported for the first time in Korea. A key to Korean species and photographs of external features are provided.     

Taxonomic revision of the tribe Zoraidini (Hemiptera: Fulgoromorpha: Derbidae) from Korea

The Korean planthopper tribe Zoraidini is revised taxonomically. Five genera are recognized in the Korean fauna: Diostrombus Uhler, 1896, Losbanosia Muir, 1917, Pamendanga Distant, 1906, Shirakiana Metcalf, 1945, Zoraida Kirkaldy, 1900. Among them, the genus Shirakiana is recorded for the first time in Korea. Nine species, four of which are recognized new to Korea: S. infumata (Matsumura), Z. koannania Matsumura, Z. hubeiensis Chou et Huang, and Z. kuwayamae (Matsumura). Previous record of one species, Z. pterophoroides (Westwood, 1851), is removed from the list of Korean fauna because it was erroneously reported, based on a misidentification. All species are described and illustrated, and identification keys to genera and species are provided.     

Taxonomic review of the genus Lymantria (Lepidoptera: Erebidae: Lymantriinae) in Korea

A taxonomic review of the Korean Lymantria Hübner, 1819 was conducted. A total of nine species of five subgenera with two unrecorded species are listed: Lymantria (Porthetria) dispar Linnaeus 1758, L. (P.) xylina Swinhoe 1903, L. (Lymantria) monacha (Linnaeus 1758), L. (L.) minomonis Matsumura 1933 (new to Korea), L. (L.) similis monachoides Schintlimeister 2004 (new to Korea), L. (L.) lucescens (Butler 1881), L. (Nyctria) mathura Moore 1865, L. (Collentria) fumida Butler 1877, and L. (Spinotria) bantaizana Matsumura 1933. Lymantria (Lymantria) minomonis and L. (L.) similis monachoides are newly added to the Korean fauna. Lymantria (L.) minomonis was found only on Bogildo Island of Jeollanam‐do in the southern part of Korea, and L. (L.) similis monachoides was collected in central Korea. Lymantria (Porthetria) xylina and L. (Collentria) fumida were not examined in this study, and it is considered that the previous records were due to misidentification or they are only distributed in the northern part of the Korean Peninsula. We provide diagnoses of two unrecorded species and adult habitus and genitalia photos of the Korean Lymantria species.     

A Taxonomic Revision of Illiberis Walker (Lepidoptera: Zygaenidae: Procridinae) in Korea

The Korean species of Illiberis Walker are revised. A total of 10 species are recognized, including four species new to Korea: I. rotundata Jordan, I. psychina (OberthÜr), I. consimilis Leech, and I. hyalina (Staudinger). The identities of I. cybele Leech and I. assimilis Jordan, the two ambiguously defined Korean species, are reconfirmed with the examination of type specimens and additional materials. Photos of the adults and type materials are provided, and male and female genitalia of each species are illustrated. Biology and distribution for each species are briefly discussed with the larval host records from Korea.
