Taxonomic Review and Revised Keys of the Korean Mosquitoes (Diptera: Culicidae)

ABSTRACT A bibliographic review on the Korean mosquitoes (Diptera: Culicidae) resulted in the recognition of 51 species and two forms of adult mosquitoes belonging to 10 genera, three subfamilies. Revised keys to genera and species of female adults of Korean mosquitoes are provided using available macro-characters. Pictorial keys are also provided for easy usage.     

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.     

Phylogenetic relationships, character evolution, and taxonomic implications within the slipper lobsters (Crustacea: Decapoda: Scyllaridae)

The slipper lobsters belong to the family Scyllaridae which contains a total of 20 genera and 89 species distributed across four subfamilies (Arctidinae, Ibacinae, Scyllarinae, and Theninae). We have collected nucleotide sequence data from regions of five different genes (16S, 18S, COI, 28S, H3) to estimate phylogenetic relationships among 54 species from the Scyllaridae with a focus on the species rich subfamily Scyllarinae. We have included in our analyses at least one representative from all 20 genera in the Scyllaridae and 35 of the 52 species within the Scyllarinae. Our resulting phylogenetic estimate shows the subfamilies are monophyletic, except for Ibacinae, which has paraphyletic relationships among genera. Many of the genera within the Scyllarinae form non-monophyletic groups, while the genera from all other subfamilies form well supported clades. We discuss the implications of this history on the evolution of morphological characters and ecological transitions (nearshore vs. offshore) within the slipper lobsters. Finally, we identify, through ancestral state character reconstructions, key morphological features diagnostic of the major clades of diversity within the Scyllaridae and relate this character evolution to current taxonomy and classification.     

The evolutionary process of bioluminescence and aposematism in cantharoid beetles (Coleoptera: Elateroidea) inferred by the analysis of 18S ribosomal DNA

Cantharoid beetles are distinctive for their leathery soft elytra and conspicuous color or bioluminescence, and many of the members are equipped with chemical defenses. Thus, the vivid coloration of Cantharidae and Lycidae and the bioluminescence in Lampyridae and Phengodidae appear to be aposematic signals. However, the evolutionary aspect of their aposematism is not well understood, because the classification of the families remains controversial. In this study, we performed molecular phylogenetic analyses of species from cantharoid families, based on nucleotide sequence comparisons of nuclear 18S ribosomal DNA. The results shows that the luminous species Rhagophthalmus ohbai, which had sometimes been classified in Lampyridae, is excluded from a lampyrid clade and associates with the taxa of Phengodidae. The molecular data also suggests that four major subfamilies of Cantharidae (Cantharinae, Chauliognathinae, Malthininae, and Silinae) form a clade. The six subfamilies of Lampyridae are grouped and classified into two sublineages: Amydetinae + Lampyrinae + Photurinae and Cyphonocerinae + Luciolinae +Ototretinae. Genera Drilaster and Stenocladius are the members of Ototretinae in Lampyridae. These results conform to traditional taxonomy but disagree with more recent cladistic analyses. Based on these findings, we propose an evolutionary process of bioluminescence and aposematism in cantharoids: the clades of Cantharidae, Lampyridae, Lycidae, and Phengodidae have evolved aposematic coloration; subsequently Lampyridae and Phengodidae acquired bioluminescence; and these four major cantharoid families achieved their current adaptive diversities.     

Contribution to the Tribes Diaperini Doyen in Korea (Coleoptera: Tenebrionidae: Diaperinae)

A taxonomic review of six genera of Korean Diaperini is presented. Seven species in Korea are described here. We provide a key to the Korean species and genera, diagnoses and photos for them.     

Morphometrical characters of the hypopygium in the Dolichopodidae (Diptera) and their use in the systematics of the family

Morphology of the hypopygium was investigated in 496 species from 128 genera of the family Dolichopodidae. Based on twenty morphological and morphometrical characteristics, a parsimonic dendrogram of the Dolichopodidae subfamilies was constructed. Variance analysis of the morphometrical data allowed revealing diagnostic characteristics for the subfamilies and genera of Dolichopodidae. Such characteristics as the relative lengths of the epandrium, surstylus, cercus, and apical and basoventral epandrial processes can be used for taxonomic diagnostics of the subfamilies and genera.     

Taxonomic Review of the Tribe Ulomini (Coleoptera, Tenebrionidae) in Korea

The tribe Ulomini of Korean Tenebrionidae is reviewed taxonomically. Korean Ulomini recorded to three genera and six species, Cneocnemis laminipes Gebien, Uloma marseuli Nakane, U. latimanus Kolbe, U. excisa Nakane, U. bonzica Marseul, Eutochia lateralis (Boheman). We have found that U. exciza was misidentified U. bonzica, and E. lateralis was not distributed in Korea as the result of this study. We confirm that two genera and four species are distributed in Korea. A key to diagnosis of the genera and species, and figures of these species are presented.
