Taxonomic Review of the Genus Trigonospila Pokorny (Diptera: Tachinidae: Blondeliini) in Korea

As a result of a taxonomic review of the tachinid genus Trigonospila Porkorny in Korea, we recognized two species: T. ludio Zetterstedt) and T. transvittata (Pandelle). The former species is reported for the first time in Korea. We here provide a key to the Korean species, redescriptions, photographs and illustrations.

A Systematic Study of Rivellia Robineau-Desvoidy in Korea, with Emphasis on the Species Allied to Rivellia basilaris (Diptera: Platystomatidae)

Abstract As a result of a taxonomic study of the Rivellia basilaris and its allied species in Korea, the following five species are recognized: R. basilaris (Wiedemann), R. flaviventris Hendel, R. nigroapicalis Byun et Suh, sp. nov., R. cestoventris Byun et Suh, sp. nov., and R. apicalis Hendel. None of the above species were previously reported in Korea. We provide descriptions and illustrations of these five species as well as a key to all 11 Korean Rivellia species. We also analysed interspecific relationships among Korean Rivellia species using cladistic methods. We propose to recognize R. basilaris species-group based on the presence of two lateral occipital setae as a synapomorphy. The monophyly of the previously recognized R. syngenesiae species-group is also supported by a single synapomorphy (outer surstylus extending beyond apex of cercus).

Revised Key and Phylogenetic Analysis of Korean Rivellia (Diptera: Platystomatidae), with Redescriptions of Two Little Known Species

A total of 12 Korean Rivellia species were previously known in Korea. As a result of the continuing effort to investigate this genus in Korea, we discovered an additional species, R. depicta Hendel. We also collected R. asiatica that was the only recorded Korean species unavailable for our previous studies of Rivellia. In the present study, we provide redescriptions of these two species and a revised key to all 13 known species of Korean Rivellia. We also reanalyzed their phylogenetic relationships based on the expanded morphological dataset.

New Dicranoptycha Osten Sacken, 1859 Crane flies (Diptera: Limoniidae) of North and South Korea

Two new species of Dicranoptycha Osten Sacken, 1859, crane flies (Diptera, Limoniidae) from the Korean peninsula are described, illustrated and compared with already known and related species. An identification key and check-list of all Korean Dicranoptycha is presented.

Molecular phylogeny of the Korean Rivellia species (Diptera: Tephritoidea: Platystomatidae) based on 16S rDNA sequences: Testing morphological hypotheses using molecular data

The phylogeny of the genus Rivellia Robineau‐Desvoidy was inferred from mitochondrial 16S ribosomal (r)DNA gene sequences of 13 Korean Rivellia species and six species representing other platystomatid genera and the family Tephritidae. We compared the inferred molecular phylogeny with the previously published morphological cladogram. As a result, the following phylogenetic relationships were recognized: (i) monophyly of the genus Rivellia; (ii) monophyly of the R. syngenesiae species group; (iii) R. depicta and R. apicalis (which were not previously placed in any species group) were recognized as a sister group of the R. syngenesiae species group; and (iv) monophyly of the R. basilaris species group was recognized to a limited extent. These results, even though geographically limited, provide a new insight into the phylogeny of the genus Rivellia. They clearly show the utility of 16S rDNA for phylogenetic analysis of the genus Rivellia. Additional study involving samples from different geographical areas will be needed to gain a better understanding of the adaptive radiation of this species‐rich genus.

Libnotes crane flies (Diptera: Limoniidae) from Jeju Island (South Korea)

The Korean species of Libnotes (Laosa) Edwards, 1926 and L. (Libnotes) Westwood, 1876 from Jeju Island are taxonomically revised. L. (Laosa) charmosyne (Alexander, 1958) and L. (Libnotes) divaricata (Alexander, 1924) are new records for South Korea and L. (Libnotes) byersiana n. sp. is described. An identification key for all Korean Libnotes, redescriptions and illustrations of the three currently known Jeju species are presented.

First description of the last instar larva and pupa of the aquatic crane fly Limnorimarga limonioides (Alexander, 1945) (Diptera: Limoniidae)

Descriptions, illustrations and habitat characteristics are given for the previously unknown larvae and pupae of the East Palaearctic monotypic aquatic crane fly genus Limnorimarga Alexander, 1945 collected from Korea in hygropetric habitats. Diagnostic features and phylogenetic relationships are discussed.

Rhipidia crane flies (Diptera: Limoniidae) from Korea.

Korean species of the crane fly genus Rhipidia Meigen, 1818 (Diptera: Limoniidae), are taxonomically revised. Rhipidia (Rhipidia) serena, new species, is described and figured. Rhipidia (R.) longa Zhang, Li, Yang, 2014, R. (R.) maculata Meigen, 1818 and R. (R.) sejuga Zhang, Li, Yang, 2014 are recorded for the first time in Korea. Previously known species, Rhipidia (R.) septentrionis Alexander, 1913 is redescribed and illustrated. Identification key for all Korean Rhipidia species is given. Most antennae, wings, male and female terminalia of all species are illustrated for the first time.

Metalimnobia crane flies (Diptera: Limoniidae) from Korea.

Korean species of the crane fly genus Metalimnobia Matsumura, 1911 (Diptera: Limoniidae), are taxonomically revised. Metalimnobia (Metalimnobia) channpayna new species, is described and figured, M. (M.) bifasciata (Schrank, 1781), M. (M.) quadrinotata (Meigen, 1818) and M. (M.) zetterstedti (Tjeder, 1968) are listed for the first time in Korea, new information for previously known species, M. (M.) quadrimaculata (Linnaeus, 1760) is added. Identification key for all Korean Metalimnobia species is given. Wings, male and female terminalia are illustrated for all species.

Heterangaeus Alexander, 1925 crane flies (Diptera: Pediciidae) of Korea

The Korean crane fly species of the genus Heterangaeus Alexander, 1925 (Diptera: Pediciidae) is taxonomically revised. H. gloriosus gloriosus (Alexander, 1924) is redescribed.
