Seasonal dispersal of water beetles (Coleoptera) in an agricultural landscape: a study using Moericke traps in northwest Spain

Information on flight dispersal in water beetles in the Iberian Peninsula is scarce. This study provides new data on the dispersion flight phenology of 21 species captured using Moericke traps in an agricultural system in León province (NW Spain) during two annual cycles (1992 and 1993). The species captured form part of the assemblage of aquatic Coleoptera commonly found in stagnant environments in the centre of the Iberian Peninsula. Most of them are good flyers and colonisers. These flights are related to two environmental variables: mean atmospheric temperature and rainfall. The results show a clear relation between temperature and the flight period as most of the specimens dispersed during peaks of high mean daily temperatures, and a negative relation with rainfall. With regard to phenology, two types of dispersion strategy were identified: flights in the middle of summer to escape from drought and flights in spring and autumn for colonising new habitats. The first group includes Hydroglyphus geminus (Fabricius) and, in particular, Helophorus brevipalpis Bedel, whose great abundance in the dispersal stage is related to parthenogenetic reproduction and the rapid production of a large number of colonising females. The second strategy corresponds to univoltine species with overwintering adults such as Helophorus alternans Gené or species from the genus Hydroporus Clairville.     

Description of Two New Bidessini Species from the Afro-tropical Region (Coleoptera,Dytiscidae)

Uvarus pinheyi sp. n. is described from Zambia and Hydroglyphus pseudoctoguttatus sp. n. from Angola. Distinguishing characteristics are given for the new taxa.     

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.     

A new species of Clytus Laicharting (Coleoptera: Cerambycidae) from Korea with a key to Korean species

A new species of Clytus Laicharting (Coleoptera: Cerambycidae) is described from Korea. Illustrations of diagnostic characteristics of the new species including male genitalia are provided with a key to Korean Clytus species.     

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 Cleridae (Coleoptera) in Korea (Part 1): Clerinae Latreille, 1802

A taxonomic review of six genera of Korean Clerinae is presented. Eleven species, including Stigmatium pilosellum (Gorham, 1878), a new Korean record, are reported in this paper. A key to the Korean species and genera, diagnoses, whole‐body photographs of adults, and illustrations of diagnostic characters are provided.     

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.     

Discovery of three new species of the genus Gyrophaena Mannerheim (Coleoptera: Staphylinidae: Aleocharinae) in Korea

Three new species of the mycophagous aleocharine genus Gyrophaena Mannerheim are described in Korea. The types and paratypes of the new species are designated. Illustrations of the diagnostic characters and habitus photographs of new species are provided with a key to Korean species of Gyrophaena.     

Description of three liocranid spider species from Korea (Araneae: Liocranidae)

Three liocranid spider species are described with illustrations: a new species, Agroeca bonghwaensis n. sp. and two species new to Korean spider fauna, Agroeca montana Hayashi, 1986 and Scotina palliardii (Koch, 1881). The occurrence of the genus Scotina Menge, 1873 is also recorded from Korea for the first time.     

Taxonomic revision of the subfamily Kermesiinae (Hemiptera: Meenoplidae) from Korea

The planthopper subfamily Kermesiinae is revised taxonomically from Korea. Two genera and three species have been recorded in the Korean fauna, among which one species is new to science: Nisia nervosa (Motschulsky 1863), Eponisiella guttulinervis (Matsumura 1914), and Eponisiella andonga sp. nov. These three species are described and illustrated. Key to genus and species 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.
