Taxonomic history of Korean Arctiidae was recently revised by Park (2000), comprising a total of 59 species, 31 genera from South Korea. Subsequently, Choi (2004, 2010) added two more arctiine species, and Bae et al. (2013) enumerated 63 species, 31 genera including one unrecorded species, and Lee et al. (2014) reported one more lithosiine species from South Korea. In the present study, we report and confirmone rare species, Spilarctia robusta (Leech, 1899), which has been reported by Nam (1985) from Jeju Is., but it has been omitted from the Check List of Insects from Korea (1994), due to that no specieman has been collected after Nam (1985). We found this species from the collection of the Korea National Arboretum (2012), and redescribed with illustrations of genitalic structure. Therefore 65 species of Arctiinae are known to the fauna of Arctiinae from South Korea.

We report Conilepia nigricosta (Leech, 1988) in Korea for the first time. The female of C. nigricosta is nearly identical to the female of Lithosia quadra, and it has caused confusion in the generic classification. Therefore, we reexamined their morphology and also performed to analyze DNA barcode region compared with species of other related genera. As the results, the significant diagnoses between the two species were reconfirmed and provided in the adult appearances, wing venations, and genital structures in both sexes. The DNA barcoding results also showed a large genetic distance ranging from 6.21% to 7.16% between the two species. In phylogenetic relationship for these two species as well as 28 related species of Lithosiina, C. nigricosta was clustered as a sister to L. quadra and they formed a strong monophyletic group. It supports a possibility that these two genera may be a single genus, but more detailed molecular analysis using additional genetic markers and samples is needed to resolve reliable phylogenetic relationships between the taxa examined in this study.

Mycetophagids, the family of primitive tenebrionoid beetles, are commonly fugivorous. They mainly feed and inhabit in the fruiting bodies of higher fungi, fungus-grown bark, and moldy vegetative materials. Some species are associated with a large variety of moldy substances and are found both outdoors in natural environments and indoors in association with a variety of stored products. They are not serious pests, and their presence is usually indicative of poor storage conditions and moldy produce. There are only five Mycetophagidae species previously recorded for Korea, Mycetophagus antennatus (Reitter 1879), M. ater (Reitter, 1879), M. hillerianus Reitter, 1874, Typhaea pallidula Reitter, 1874, and T. stercorea (Linnaeus 1758). In the course of this study, 60 specimens from 12 sites of Korean Mycetophagidae were examined. We reviewed taxonomically four genera and nine species in Korea. Among them, four species including Eulagius ussuriensis Nikitsky, 1988, Litargus japonicus Reitter, 1877, Mycetophagus irroratus (Reitter,1879), and Mycetophagus pustulosus (Reitter,1889) are newly recorded in Korea. We also obtained additional bionomic data for the seven species including their host fungi and habitat based on field observations and laboratoryrearing data in part.

New record of family of arhynchobdellida leeches (Orobdellidae) from Gageodo Island is presented. We have surveyed for land leeches in Korea from July to September in 2011 and found 1 species. This is Orobdella tsushimensis Nakano, 2011, reported for the first time in Korean Peninsula. This species gets the following characteristics: IV unianulate; 1/2+5 annuli between gonopores; bottle-shaped gastroporal duct; and epididymides in XVII–XIX. According to their morphological features, the diagnosis of O. tsushimensis is slightly emended. Phylogenetic analyses using mitochondrial COI, tRNACys, tRNAMet, 12SrDNA, tRNAVal and 16SrDNA markers show that the Orobdella specimen from Gageodo Isl. and O. tsushimensis from Tsushima Island, Japan, form a monophyletic clade and also confirm the identification of the Orobdella specimens from Gageodo Isl.

New record of family of arhynchobdellid leeches (Hirudiniformes: Haemadipsidae) from Korea is presented. We have surveyed for land leeches in Korea from July to September in 2011 and found 1 species. This is Haemadipsa rjukjuana Oka, 1910, reported for the first time in Korean Peninsula. This species is terrestrial blood-feeding leech which attacks medium or large sized mammals primarily, including human and originally distributed in East and South East Asia, including Indochinese Peninsula, Malay Peninsula, Ryukyu Islands and Taiwan. In Japan, the number and areas of habitats of land leech have been rapidly expanded since 1970s and many leeches attack forest workers, hikers and resident during May to September. As a result of climate change, same situation can be reproduced in Korean Peninsula. We firstly report the occurrence of blood-feeding land leech, the behavior on human being and distributions in Korea. Also, we obtained the sequence of the mitochondrial gene (COI) and additional biology is discussed for this species according to collection data.

Twelve species of the genus Nola, including a new species, Nola longicosta sp. nov. are recognized from Korea. Among them, six species, Nola cristatula(Hubner), N. yoshinensis(wileman & West), N. japonibia(Strand), N. nami(Inoue), N. ebatoi(Inoue), and N. okanoi(Inoue) are reported for the first time from Korea. Genital characteristics of the species are briefly described with illustration, and all available collecting data are given.

In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy which minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle. Here, we have used germ line markers (piwi, vasa and nanos) and micro-injected cell lineage tracers to show that PGC specification in the leech genus Helobdella follows a different scenario: in this hermaphrodite, the male and female PGCs segregate from somatic lineages only after more than 20 rounds of zygotic mitosis; the male and female PGCs share the same (mesodermal) cell lineage for 19 rounds of zygotic mitosis. Moreover, while all three markers are expressed in both male and female reproductive tissues of the adult, they are expressed differentially between the male and female PGCs of the developing embryo: piwi and vasa are expressed preferentially in female PGCs at a time when nanos is expressed preferentially in male PGCs. A priori, the delayed segregation of male and female PGCs from somatic tissues and from one another increases the probability of mutations affecting both male and female PGCs of a given individual. We speculate that this suite of features, combined with a capacity for selffertilization, may contribute to the dramatically rearranged genome of Helobdella robusta relative to various other animals.
