Seven species of the family Candonidae Kaufmann, 1900 are reported from South Korea. Five species are described as new, all belonging to the subfamily Candoninae Kaufmann, 1900 and the tribe Candonini Kaufmann, 1900: Candona quasiakaina sp. nov., C. sillae sp. nov., Fabaeformiscandona koreana sp. nov., Typhlocypris choi sp. nov., and Schellencandona tea sp. nov. A very close resemblance between Candona sillae and the European C. improvisa Ostermeyer, 1937 prompted a redescription of the latter species based on the type material, and designation of the lectotype. One species of the tribe Candonopsini, Candonopsis transgrediens Brehm, 1923, previously known only from China, is reported from Korean freshwater habitats, and its first redescription is provided, along with a key to the world representatives of the genus Candonopsis Vávra, 1820. One species of the subfamily Paracypridinae, Dolerocypria mukaishimensis Okubo, 1980, previously known only from Japan, is redescribed from Korean brackish water habitats, and some notes on its variability are provided. A checklist of the Candonidae ostracods from East Asia is also provided, but only for those species that have been well-documented and taxonomically described.

Introduction: The family Benthopectinidae is composed of deep-sea sea stars distributed in eight genera and approximately 70 valid species. So far, only five species of this family have been reported for the Mexican waters of the Gulf of Mexico. Objective: To provide an updated local taxonomy of this family. Methods: A total of 566 specimens deposited in the Echinoderm National Collection, Instituto de Ciencias del Mar y Limnología, Universidad Nacional Autónoma de México, and the National Museum of Natural History, Smithsonian Institution, collected from 1952 to 2015, were taxonomically examined. Results: We present descriptions, photographs, and an illustrated dichotomous key for Benthopecten simplex simplex, Cheiraster (Barbadosaster) echinulatus, Cheiraster (Cheiraster) planus, Cheiraster (Christopheraster) blakei, and Cheiraster (Christopheraster) mirabilis in the region. Conclusions: The five studied species represent 6 % of the world biodiversity of the family and can now be identified with the illustrated key.

The family Monhysteridae is characterized by 17 valid genera, seven of which are known to be free-living, inhabiting marine sediments. In total, 70 valid marine species are ascribed to these seven genera. Overall, the family is characterized by a confused taxonomic history with a large list of synonyms and species inquirendae. The taxonomic problem is not restricted to the old literature, but inconsistencies also appeared in recent studies. The aim of this study is to show the most important diagnostic characters to identify each genus and provide taxonomic tools for species identification. Dichotomous-keys and illustration-guides are attempted for the marine monhysterid species. For the family and each subfamily, tribe and marine genus a brief historical background, diagnosis and a list of valid species is provided. Hereby, we propose to transfer eight species of the genus Thalassomonhystera to the genus Monhystrella.

A number of species of the family Pectinidae (Lamellibranchia, Mollusca) are of considerable commercial importance in many parts of the world. Many of these are being reared in laboratories and hatcheries and this has made easier studies of cytogenetics using eggs and embryos, and ultimately will make studies of their genetics feasible. Recently, simple squash techniques have provided a fast and reliable method for obtaining chromosome numbers from eggs and embryos of several bivalves including Mercenaria spp. (Menzel & Menzel, 1965), Ostrea lurida and Crassostera gigas (Ahmed & Sparks, 1967), Mytilus spp. (Ahmed & Sparks, 1970), and Crassostrea spp. (Menzel, 1968). In 1967, Longwell, Stiles & Smith published the karyotype of Crassostrea virginica obtained from embryos which had been treated with colchicine.

A worldwide checklist is provided for the family Endomychidae (Coleoptera: Cucujoidea). An updated subfamilial classification is presented, based on recent higher-level phylogenetic analyses and incorporating many recently described taxa. At present, Endomychidae contains 1782 valid species and subspecies in 130 genera organized into 12 subfamilies. Two new synonyms are recognized: Symbiotes latus Redtenbacher, 1849 = Symbiotes latus var. roberti Falcoz & Roman, 1930 syn. nov.; and Cholovocerida Belon, 1884 = Displotera Reitter, 1887b syn. nov. Two new combinations are proposed: Cholovocerida ecitonis (Wasmann, 1890) for Coluocera ecitonis Wasmann, 1890 comb. nov.; and Cholovocerida maderae (Wollaston, 1854) for Cholovocera maderae Wollaston, 1854 comb. nov. Loeblia ceylanica Dajoz, 1972a is here designated as the type species for Loeblia Dajoz, 1972a, and Rhymbus hemisphaericus Gerstaecker, 1858 is designated as the type species for Rhymbus Gerstaecker, 1858. Nomen nudum status is proposed for Mycetaea tafilaletica Smirnoff, 1957. Thirty-two species originally described under Corynomalus Chevrolat, 1836 and subsequently transferred to Amphix Laporte, 1840, have been returned to Corynomalus. Known fossil taxa are summarized.

AbstractThe archaic cynipoid family Ibaliidae is revised. All described taxa are included in a checklist, and keys to valid taxa are presented. Host records include larvae of several woodwasp species (Siricidae: Siricinae and Tremicinae). Ibaliidae is considered to include the East Asian genus Heteribalia Sakagami, with five valid species, and the mainly Holarctic genus Ibalia Latreille, with 13 valid species, seven in the subgenus Ibalia and six in the subgenus Tremibalia. Heteribalia aureopilosa Maa, 1949 and H. subtilis Maa, 1949 are raised from subspecies to species level. Ibalia (T.) hunanica sp. n., is described from Oriental China. Three morphs of I. (T.) anceps, differing in wing colour pattern, are recognized, and distribution records of these morphs in North America are mapped. I. scalpellator Westwood, 1837 is synonymized with I. anceps Say, 1824; I. takaehihoi Yasumatsu, 1937 with I. jakowlewi Jacobson, 1899; I.fulviceras Yang, 1991 with I. ornata Belizin, 1968; and I. yunshae Yang et Liu,1992 with I. rufipes drewseni Borries, 1891. Lectotypes are designated for I. picea Matsumura, 1912 (syn. of I. leucospoides (Hochenwarth, 1785)) and for I. japonica Matsumura, 1912.

Species Inquirendae

In the context of exploration of meiofauna in a sandy intertidal zone of Jeju Island (South Korea), over 70 nematode species are identified, some which have been proven to be new for science. Two new free-living marine nematode species of the family Selachinematidae (Chromadorida, Selachinematidae, Choniolaiminae) are described from the intertidal sandy sediments of Jeju Island (South Korea). Gammanema okhlopkovi sp. n. is closest to Gammanema anthostoma (Okhlopkov, 2002) and differs by having longer cephalic setae (8.5–19 μm in G. okhlopkovi versus 6–7.5 μm in G. anthostoma) and by the presence of precloacal supplementary organs. The genus diagnosis of Gammanema is updated. The genus includes fourteen valid species, while three species are considered species inquirendae due to incomplete diagnoses and illustrations impeding their correct recognition. An annotated list of valid and invalid Gammanema species is provided. A pictorial key for valid Gammanema species is constructed, which consists of two components: (1) simplified images of heads, and (2) a table summarizing most of the significant measured and numeric characters between species. Latronema obscuramphis sp. n. differs from its related species Latronema aberrans (Allgén 1934), Latronema annulatum (Gerlach, 1953), and Latronema spinosum (Andrássy, 1973) by body size, number of supplementary organs, tail shape, length of spicules, and cuticle ornamentation.

A list of all valid 6,206 extant and 296 fossil species of Ceratopogonidae described worldwide is provided, along with all their synonyms. A full citation and the country of origin of the type is given, with some larger countries also providing a more specific state or province. For the first time, worldwide, nomina dubia are identified. Numbers of species of each genus and subgenus are listed. Within subfamilies and tribes, genera are listed alphabetically. Five species have newly recognized authors, four have new names and 28 new combinations are recognized, with these listed in a table. A commentary on the state of the systematics in the family and particularly of Culicoides Latreille is given. The museums of the world are listed with the types of various authors of Ceratopogonidae species indicated. Authors providing regional catalogs, as well as summation of various collections are tabulated. The rate of description since 1758 indicates a steady progression of description, with, for example, 1,231 valid species described since the compilation of the world species by Borkent & Wirth (1997), till the end of 2018. The diversity in each Region is compared and the numbers of species shared between adjacent Regions presented.

A new genus of Parastenheliidae, Johnwellsia gen. nov., is proposed for its type and only species, J. bipartita sp. nov., collected from Dadeji Beach in Xiamen, Taiwan Strait, China. The intricate taxonomic history of the family is reviewed with special emphasis on its type genus Parastenhelia Thompson & Scott, 1903. It is concluded that P. hornelli Thompson & Scott, 1903 is the type of the genus and that the widely adopted previous designation of Harpacticus spinosus Fischer, 1860 as type species of Parastenhelia is invalid. The taxonomic concept of Parastenhelia is restricted to the hornelli­-group which includes four valid species: P. hornelli, P. similis Thompson & Scott, 1903, P. oligochaeta Wells & Rao, 1987, and P. willemvervoorti sp. nov.                 The currently accepted concept of Parastenhelia spinosa as a highly variable cosmopolitan species is rejected. The genus Microthalestris Sars, 1905 (type: Thalestris forficula Claus, 1863) is resurrected to accommodate most Parastenhelia species that were previously placed in the spinosa-group. Two species, Thalestris forficuloides Scott & Scott, 1894 and Parastenhelia antarctica Scott, 1912, are reinstated as valid members of the genus which further includes Parastenhelia gracilis Brady, 1910, Microthalestris littoralis Sars, 1911, P. costata Pallares, 1982, P. minuta Pallares, 1982, P. bulbosa Gee, 2006 and five new species: M. campbelliensis sp. nov.; M. polaris sp. nov.; M. santacruzensis sp. nov.; M. sarsi sp. nov. and M. variabilis sp. nov. Both the type species, Thalestris forficula, and Harpacticus spinosus are considered species inquirendae in Microthalestris. Three new genera are proposed to accommodate the remaining Parastenhelia species. Porirualia gen. nov. contains P. megarostrum Wells, Hicks & Coull, 1982 (type) and P. pyriformis Song, Kim & Chang, 2003, and is the sistergroup of Johnwellsia gen. nov. Parastenhelia aydini Kuru & Karaytuğ, 2015 is placed in the monotypic genus Karaytugia gen. nov. while all species with penicillate elements on the antenna and P1 are transferred to Penicillicaris gen. nov., including Thalestris pectinimana Car, 1884, which is removed from the synonyms of the Parastenhelia spinosa (Fischer, 1860) “complex”, and three new species: P. maldivensis sp. nov., P. penicillata sp. nov., and P. sewelli sp. nov.                 The genus Karllangia Noodt, 1964 (type: K. arenicola Noodt, 1964) is relegated to a junior subjective synonym of Thalestrella Monard, 1935a (type: T. ornatissima Monard, 1935a). New or updated diagnoses for each genus, and differential diagnoses for species where appropriate, are provided. A key to the ten currently recognized genera in the Parastenheliidae is presented as well as keys to species for Parastenhelia, Microthalestris, Thalestrella and Penicillicaris gen. nov.
