First Record of Potentially Pathogenic Amoeba Vermamoeba vermiformis (Lobosea: Gymnamoebia) Isolated from a Freshwater of Dokdo Island in the East Sea, Korea
Park, Jong Soo ;
Animal Systematics, Evolution and Diversity, volume 32, issue 1, 2016, Pages 1~8
DOI : 10.5635/ASED.2016.32.1.001
Vermamoeba vermiformis is a very important free-living amoeba for human health in association with Legionnaires` disease and keratitis. This interesting amoeba was firstly isolated from a freshwater of Dokdo (island), which was historically used for drinking water. Trophozoites and cyst forms of V. vermiformis strain MG1 are very similar to previous reported species. Trophozoites of V. vermiformis strain MG1 showed cylindrical shape with prominent anterior hyaline region. The average ratio of length and width was about 6.5. Typically, cysts of the strain MG1 showed a spherical or slightly ovoidal shape with smooth wall, and lacked cyst pores. Some cysts had crenulate-walled ectocyst, which was separated from endocyst wall. Further, 18S rRNA gene sequence of V. vermiformis strain MG1 showed very high similarity to other V. vermiformis species (99.4%-99.9% identity). Molecular phylogenetic analysis based on 18S rRNA gene sequences clearly confirmed that the isolate was one strain of V. vermiformis with maximum bootstrap value (maximum likelihood: 100%) and Bayesian posterior probability of 1. Thus, the freshwater of Dokdo in Korea could harbor potentially pathogenic amoeba that may cause diseases in humans.
Two New Species of Echiuricopus n. gen. (Copepoda, Poecilostomatoida) Associated with Echiurans from the Yellow Sea
Kim, Il-Hoi ;

DOI : 10.5635/ASED.2016.32.1.009
Two new species of poecilostomatoid copepods associated with echiurans are described from an intertidal mud flat in the Yellow Sea. A new genus Echiuricopus is created to accommodate two new species, E. aprilis and E. tenuipes. Major differences between the two new species are displayed in body length, length of caudal ramus seta I, length/width ratio of leg 5 exopod, and armature of the first antennular segment. Echiuricopus n. gen. is closely related to the genus Goidelia Embleton, 1901, but is distinguished from the latter chiefly by having seven caudal setae, a claw-like process on the first antennular segment, one claw-like process on the maxillary syncoxa, the absence of an inner coxal seta on legs 1-4, different armatures on legs 1-4, and an elongate leg 5 exopod.
Additions to the Knowledge of the Genus Phimenes (Hymenoptera: Vespidae: Eumeninae) from Vietnam
Nguyen, Lien Thi Phuong ; Nguyen, Dac Dai ; Carpenter, James M. ;
Animal Systematics, Evolution and Diversity, volume 32, issue 1, 2016, Pages 21~27
DOI : 10.5635/ASED.2016.32.1.021
The solitary wasp genus Phimenes (Hymenoptera: Vespidae: Eumeninae) was reported to occur in Vietnam by , represented by one taxon, Phimenes flavopictus continentalis (Zimmermann), which was synonymized under nominotypical Phimenes flavopictus by . A note on gender of this genus is made in the text. One more species, Phimenes indosinensis is recorded in this study from Dak Lak in the southern and Son La in the northwestern parts of Vietnam for the first time. Detailed descriptions of the female and male of the latter are provided with figures. A key to the two species from Vietnam is also provided.

DOI : 10.5635/ASED.2016.32.1.028
We describe the morphological characteristics of two morids, Gadella jordani and Physiculus japonicus, belonging to the order Gadiformes, based on Korean specimens collected from the Korean ocean. Two specimens of Gadella jordani was first collected from Jeju Island, Korea and the East Sea, Korea, in 2013-2014. This species is characterized by 8, 67-69 dorsal fin rays, 66-71 anal fin rays, 5+13 gill rakers, no barbel on the lower jaw, no vomerine teeth, and a ventral luminous organ closer to the anus than to the interventral line. We described it as the first record to the Korean fish fauna, and proposed the new Korean name "Min-su-yeom-dae-gu-sok" for the genus Gadella, and "Min-su-yeom-dae-gu" for the species G. jordani. Physiculus japonicus was first reported by Koh and Moon in the year 1999 based on a single specimen in Korea. However, no study has been attempted to describe the morphological characteristics in Korea since then. In 2013-2014, three specimens of P. japonicus was collected from Jeju Island, Korea and the East Sea, Korea, and we redescribe P. japonicus in detail. This species is characterized by 9-10, 63-64 dorsal fin rays, 70-73 anal fin rays, 3+7-8 gill rakers, a short barbel on the lower jaw, and a ventral luminous organ equidistant between the interventral line and the anus.
A New Record of Dendrophyllia compressa (Anthozoa: Hexacorallia: Scleractinia: Dendrophylliidae) from Korea
Choi, Eunae ; Song, Jun-Im ;
Animal Systematics, Evolution and Diversity, volume 32, issue 1, 2016, Pages 38~43
DOI : 10.5635/ASED.2016.32.1.038
Dendrophyllia compressa Ogawa and Takahashi, 1995 is newly reported from Korea. The specimen was collected off Seogwipo, Jeju-do, Korea in 1969. It is described herein based on the morphological characters of the skeletal structures. Dendrophyllia compressa is characterized by its small and bushy growth form with branches, vertical growth direction, small calicular diameter, compressed calice, Pourtalès Plan with vertical septal inner edges, flat and spongy columella, exserted septal upper margins, and epitheca. Dendrophyllia compressa has been synonymized with Cladopsammia eguchii . However, the former species differs from the latter species in its growth form, growth direction, colony size, corallite size, and corallite shape.
An Updated Checklist and Perspective Study of Millipedes (Arthropoda: Myriapoda: Diplopoda) in the Korean Peninsula
Nguyen, Anh D. ; Jang, Kuem Hee ; Hyun, Jung Su ; Hwang, Ui Wook ;

The Korean peninsula has diverse habitats and so would be expected to have a rich millipede fauna because of its location between the Paleoarctic and Oriental regions. To facilitate studies on millipedes, this work provides an updated list and discussion of Korean millipedes. A total of 69 species had been recorded up to 2010, but since then no new species have been reported. Among 69 species, 49 are endemic to the Korean peninsula. From 1950 to the present, an average of only seven new species from the Korean peninsula has been described per decade. This number does not reflect the biodiversity of millipedes in Korea, especially when compared to Taiwan, which has only one-third the area of the Korean peninsula, but from which a greater number of millipede species have been recorded (75 vs. 69 species). Japan has twofold the land area of the Korean peninsula, and an almost threefold higher number of millipede species. Further, more-intensive surveys will likely result in identification of more millipede species in the Korean peninsula.
Taxonomic Note on Nannastacus nyctagineus (Crustacea: Cumacea: Nannastacidae) from Korean Waters
Lee, Chang-Mok ; Kim, Sung-Hyun ; Kim, Young-Hyo ;

DOI : 10.5635/ASED.2016.32.1.049
Korean nannastacids have recorded only eight species belonging to genera Campylaspis and Cumella. In this paper, Nannastacus nyctagineus Gamȏ, 1962, is redescribed and illustrated as a new species of Korean fauna in this study for the first time. Korean female specimens of Nannastacus nyctagineus correspond well with the original description by Gamȏ, 1962 based on only female specimens. Gamȏ has described that new species, Nannastacus pruinosus could be distinguished from N. nyctagineus based on only male specimens. The Korean male specimens of N. nyctagineus undoubtedly match well with the description of N. pruinosus with the following common features: the surface of the carapace is covered with numerous granules; pereonites and pleonites have similar patterns of the teeth on dorsal surface; the proportion and armature of the dactylus of pereopod 2 is similar; the number and pattern arrangement of the setae on the surface in antenna 1, pereopod 1, and uropod are the all most same. Nannastacus pruinosus Gamȏ, 1962 is proposed as a synonym of N. nyctagineus described in this study. This represents the first record on the genus Nannastacus from Korea.
First Records of the Genus Parthenocodrus (Hymenoptera: Proctotrupidae) from Japan and South Korea
Kim, Chang-Jun ; Park, Bia ; Lee, Jong-Wook ;
Animal Systematics, Evolution and Diversity, volume 32, issue 1, 2016, Pages 55~59
DOI : 10.5635/ASED.2016.32.1.055
Two species of the genus Parthenocodrus Pschorn-Walcher, 1958 (Hymenoptera: Proctotrupidae) are reported: P. elongatus from Japan and South Korea and P. puncticauda from South Korea. Parthenocodrus elongatus is easily distinguished by having posterior surface of propodeum without transverse carinae and ovipositor sheath with distinct longitudinal striations. Parthenocodrus puncticauda is easily distinguished by having posterior surface of propodeum with transverse carinae and ovipositor sheath without distinct longitudinal striations. This genus is also newly recorded in each country. Redescriptions and photographs of the diagnostic characters are provided. All specimens for this study are deposited in the Yeungnam University (YNU), Gyeongsan-si, South Korea.

DOI : 10.5635/ASED.2016.32.1.060
A colonial ascidian, Synoicum clavatum has previously been reported from Japan. Here, we provide detailed descriptions and illustrations of S. clavatum as the first record in Korea. Synoicum clavatum is characterized by club-shaped colonies with oval head and elongate stalk, circular cloacal systems, a branchial sac with 14-16 stigmata rows of 10-17 stigmata per row and a stomach with smooth surface. The specimens of S. clavatum were collected in the subtidal zone (15-25 m depth) at Beomseom and Mumseom in Jeju-do while SCUBA diving from 2000 to 2014.
