Current state of knowledge of the Korean Cynipini: subspecies description,new combinations and checklist (Hymenoptera,Cynipidae)

Prior to this study, only 8 species of oak gall-forming wasps were known from Korea. After material examination and an exhaustive bibliographic revision, a total of 17 oak gall wasps species have been reported. The following species correspond to new records: Andricus hakonensis (Ahmead); A. pseudocurvator Tang & Melika; A. songshui Tang & Melika; Cerroneuroterus folimargo (Monzen); C. monzeni (Dettmer); C. vonkuenburgi (Dettmer); Neuroterus hakonensis Ashmead, Trichagalma acutissimae (Monzen), T. formosana Melika & Tang. It was impossible to obtain adult specimens for all the species, and and the following species are recorded only based on galls: Andricus kashiwaphilus Abe; A. mukaigawae (Mukaigawa); A. pseudoflos (Monzen); A. targionii Kieffer; Cerroneuroterus folimargo (Monzen); C. monzeni (Dettmer); Neuroterus hakonensis Ashmead; Trichagalma acutissimae (Monzen). The species Dryocosmus kunugiphagus Ide & Abe, 2015 is transferred to the genus Plagiotrochus: Plagiotrochus kunugiphagus (Ide & Abe, 2015) n. comb. Additionally a new subspecies of Trichagalma formosana is described to include the material from Korea and Mainland China, closely related but morphologically different to the Taiwan populations. For each species live cycle, morphology of galls, hosts, phenology, and distribution are commented. In some of them taxonomic or morphological comments are mentioned and a key of agamic Trichagalma with dark smoky pigmented spots in the forewing is added. All galls are illustrated. An up-to-date checklist of the Korean Cynipini is provided. The previously reported species from Korea (Andricus noliquercicola Shinji, 1938; Aphelonyx crispulae Mukaigawae, 1920; Neuroterus narae Shinji, 1941 and Neuroterus nawai Ashmead, 1904) are here excluded from the Korean species list.

The bee genus Chilicola Spinola (Xeromelissinae) is recorded from the State of Bahia, Brazil for the first time, based on a new species of the megalostigma group of the subgenus Hylaeosoma Ashmead. Chilicola (Hylaeosoma) kevani sp. n. is described and figured from males collected in Wesceslau Guimarães, Bahia. The species can be distinguished on the basis of coloration, size, integumental sculpturing, and structure of the hidden metasomal sterna and genitalia. A revised key to the species of the megalostigma group is provided.     

First Record of the Late Eocene Ichneumon Fly <Emphasis Type="Italic">Rasnitsynites tarsalis</Emphasis> Kasparyan (Ichneumonidae,Townesitinae) in Ukraine Confirms Correlation of the Upper Eocene Lagerstätten

Rasnitsynites tarsalis Kasparyan (Ichneumonidae, Townesitinae) described from the Baltic amber is recorded for the first time in the Rovno amber (Gulyanka, Zhitomir Region); therefore, this is the southernmost and easternmost find of Townesitinae. The presence of numerous extinct taxa of Townesitinae and tribes of Hybrizoninae Blanchard 1845 = Paxylommatinae Förster, 1862 = Hybrizontinae Marshall, 1872 confirms close relation of the Bembridge Marls fauna (Upper Eocene of England) and that of the succinites (Baltic, Rovno, and other Late Eocene European ambers); they are common in the succinites and in the Bembridge Marls and are only known from these localities.     

Taxonomic review of genus Diaparsis Förster (Hymenoptera: Ichneumonidae: Tersilochinae) from South Korea

One new species, D. koreana Khalaim, et al., sp. nov., is described, and six species, D. carinifer (Thomson), D. convexa Khalaim, D. egregia Khalaim, D. hyperae Kusigemati, D. jucunda (Holmgren) and D. neoplicator Khalaim, are recorded from this country for the first time. Diaparsis hyperae and D. pulchra are the most abundant species of the genus in the Korean fauna. A key to eleven species of Diaparsis occurring in South Korea is provided.     

Evidence of two inapparent nonoccluded viral infections of Culex tarsalis

Culex tarsalis from a mosquito colony maintained at Bakersfield, California, were infected with two noninclusion cytoplasmic viruses. Both viruses were polyhedral with average diameters of ca. 56 nm and 33 nm for C. tarsalis virus 1 and 2 (CTV1 and CTV2), respectively. CTV1 particles had an average prevalence in the colony of 24% over a 2-year period and CTV2 had a prevalence of 5%.The viruses were first observed in negatively stained preparations of crushed heads using sodium phosphotungstate. Both viruses were seen in thin sectioned material from the salivary glands, fat body, and nervous tissue of infected mosquitoes.CTV1 was retained through six serial passages by needle inoculations of infected mosquito suspensions into virus-free C. tarsalis adults. An estimated total dilution of >;10¹⁸ indicated CTV1 had multiplied in C. tarsalis. The coincident appearance of CTV2 in some of the inoculated mosquitoes through the 5th passage suggested that this virus also multiplied on serial passage.CTV1 had a median incubation period of ca. 6.6 days in adult C. tarsalis kept at 25°C. Preliminary data indicated that the median survival period of male and female C. tarsalis injected with CTV1 was reduced 2 or 3 days over that of inoculated control insects when incubated at 25°C. Infection may cause a degeneration of salivary glands in adult females.CTV1 did not infect Culex pipiens and did not produce plaques in Vero or duck embryo cell cultures.     

A supplement to the grassfly fauna of Japan (Diptera, Chloropidae)

Two new grassfly species, Gampsocera diversicolor closely related to G. tenuisinuosa Kanmiya, 1983 and Conioscinella subdivitis closely related to C. divitis Nartshuk, 1971, are described from Japan. Keys for the new species are given. Oscinisoma ussuriense Nartshuk, 1973, known in Primorskii Territory of Russia and Korea, was found in Japan (Honshu Island) for the first time. The genus Oscinisoma Lioy, 1864 was also first recorded in Japan.     

First record of Balcha Walker (Hymenoptera,Eupelmidae) in South Korea with the description of one new species

The genus Balcha Walker (Eupelmidae) is recorded for the first time in South Korea, with one newly described species and one newly recorded species. Both sexes of Balcha opaca Fusu sp. n. are described, and the presumed male of B. dictyota Gibson is described for the first time. The newly described species is peculiar in having a comparatively darker and less shiny mesoscutum. In other species of the genus the mesoscutum has brilliant metallic colours that contrast with dorsal dark bands along areas of much finer sculpture.     

Review of the genus Zygoneura Meigen (Diptera: Sciaridae) in Korea,with an updated checklist of the World species

The taxonomy of Zygoneura Meigen, 1830 (Diptera: Sciaridae) is studied. A total of three species of Zygoneura is found in Korea: Zygoneura (Zygoneura) sciarina Meigen, 1830, Zygoneura (Pharetratula) bidens (Mamaev, 1968), and Zygoneura (Pharetratula) flavicornis (Mamaev, 1968). Z. bidens is recorded from Korea for the first time. All three species are redescribed and illustrated, and a key to the Korean species is given. Furthermore, an updated world checklist of all species of Zygoneura is presented.     

Three Nematode Species Recovered from Terrestrial Snakes in Republic of Korea

The majority of parasitological studies of terrestrial snakes in Korea have focused on zoonotic parasites. However, in the present study, we describe 3 unrecorded nematode species recovered from 5 species of snakes (n=6) in Korea. The examined snakes, all confiscated from illegal hunters, were donated by the Chungnam Wild Animal Rescue Center and Korean Broadcasting System in July 2014 and February 2015. Light and scanning electron microscopies on the shapes of spicules that are either bent or straight (kalicephalids) and the presence of the intestinal cecum (ophidascarids) figured out 3 nematodes; Kalicephalus brachycephalus Maplestone, 1931, Kalicephalus sinensis Hsü, 1934, and Ophidascaris excavata Hsü and Hoeppli, 1934. These 3 species of nematode faunas are recorded for the first time in Korea.
