The first record of Conchodytes nipponensis (De Haan, 1844) (Crustacea: Decapoda: Palaemonidae) associated with pen shell Atrina pectinata (Linnaeus, 1767) (Mollusca: Bivalvia) from Korea

DOI : 10.12651/JSR.2013.2.1.001
Conchodytes nipponensis (De Haan, 1844), a caridean shrimp living in the mantle cavity of a pen shell (Atrina pectinata) is reported for the first time from Korea. It was collected from a depth of 15 m depth. Its morphology is described and illustrated, and a color image of a living specimen is provided. This is at the same time the first record of the genus Conchodytes, and the first record of a bivalve mollucs associated shrimp, from Korea.

Jung, Daewui ; Lee, Jongrak ; Kim, Chang-Bae ;

DOI : 10.12651/JSR.2013.2.1.007
During a systematic study on Korean nudibranchs, two phyllidiid and two polycerid species were collected and identified with examination of their external morphological characters. As a result of the study, two phyllidiid species, Phyllidia ocellata Cuvier, 1804 and Phyllidiella pustulosa (Cuvier, 1804) were redescribed since there was no descriptions of these species with Korean specimens. And two polycerid species, Thecacera pennigera (Montagu, 1815) and Triopha catalinae (Cooper, 1863) were described as new to Korean fauna. Diagnostic characters of these species are described with illustrations in this study. DNA barcode data from three species examined were also provided for a supplement to morphological identifications.
Jeju-do earthworms (Oligochaeta: Megadrilacea)-Quelpart Island revisited
Blakemore, Robert J. ;
Journal of Species Research, volume 2, issue 1, 2013, Pages 15~54
DOI : 10.12651/JSR.2013.2.1.015
Surveys on Jeju-do (Quelpart Isl.) unearthed about 40 earthworm species or sub-species. Several considered new to science are described. Only a dozen were previously known and these are taxonomically reviewed. The two most commonly recorded in surveys by S. Kobayashi in the 1930s were Drawida anchingiana Chen, 1933 and Metaphire quelparta (Kobayashi, 1937), neither recently relocated. Morphologically similar taxa, supported with DNA barcodes, for Moniligastridae, are Drawida anchingiana seogwipo, D. anchingiana halla and D. iucn spp. or sub-spp. nov. For Megascolecidae, new taxa and synonyms are: Amynthas arx and A. aucklandis spp. nov. that have seminal grooves rather than the eversible male pores of Metaphire plus Amynthas simplex is another new species. Amynthas sangumburi Hong & Kim, 2002 is recognized as a probable new synonym within the A. corticis (Kinberg, 1867) species-group while Amynthas corticis saeseum sub-sp nov. is described. Amynthas gracilis (Kinberg, 1867) is a new record from Jeju and Korea (with A. bouchei, A. omodeoi and A. edwardsi all by Zhao & Qiu, 2009 possible synonyms of this species group from China) with a Jejuan sub-species, A. gracilis insularum, sub-sp. nov. Presence on Jeju of Amynthas carnosus (Goto & Hatai, 1899) is confirmed (its further new synonyms are Chinese A. fuscus Qiu & Sun, 2012 and A. taiwumontis Shen et al., 2013), as is A. micronarius (Goto & Hatai, 1898) (with new synonym A. montanus Qiu & Sun, 2012 also an invalid secondary homonym). Amynthas phaselus maculosus (Hatai, 1930) is in new combination with A. kamitai (Kobayashi, 1934) and A. minjae Hong, 2001 syns. nov. Two newly described Metaphire quelparta sub-spp are M. q. seogwipo and M. q. valhalla these being supported with DNA barcodes despite the nominal taxon not yet being confirmed.
Ulleung-do earthworms - Dagelet Island revisited
Blakemore, Robert J. ;
Journal of Species Research, volume 2, issue 1, 2013, Pages 55~68
DOI : 10.12651/JSR.2013.2.1.055
Previous surveys on Ulleung-do (Dagelet Isl.) found just ten earthworm taxa while the current survey unearthed a dozen species. Placement of parthenogenetic 'tube' Amynthas dageletensis Hong & Kim, 2005 is resolved as it clearly belongs in synonymy of Metaphire soulensis (Kobayashi, 1938) which becomes a new Ulleung-do record. Other new megascolecids are recorded since Amynthas heteropodus (Goto & Hatai, 1898) and A. baemsagolensis Hong & James, 2001 are confirmed as synonyms of A. corticis (Kinberg, 1867) and A. carnosus (Goto & Hatai, 1899), respectively. The latter taxon is differentiated and its synonym A. pingi (Stephenson, 1925) provisionally revived. New lumbricids are Bimastos parvus (Eisen, 1874), Eisenia japonica (Michaelsen, 1892) and questionably Dendrodrilus rubidus (Savigny, 1826). All confirmed species are common exotics with no endemics. Drawida moniligastrids were not yet located on this remote island for reasons unknown.
First report of Dryopteris namegatae and reexamination of D. hangchowensis (Dryopteridaceae) from Korea
Lee, Chang Shook ; Lee, Kanghyup ; Hwang, Youngsim ;
Journal of Species Research, volume 2, issue 1, 2013, Pages 69~77
DOI : 10.12651/JSR.2013.2.1.069
One newly recorded species, Dryopteris namegatae, sect. Hirtipedes, was collected in forests in Jeju-do. Dryopteris namegatae (vernacular name: 'Tam-ra-top-ji-ne-go-sa-ri') was distinguished from other Korean congeners of sect. Hirtipedes of the genus Dryopteris by having stiff black scales on stipe and rachis, less narrowed base of lamina, and adaxial surface of pinna immersed along veins. Dryopteris hangchowensis ('Gak-si-top-ji-ne-go-sa-ri', new local name), recorded without any comments and description, was reexamined with similar taxa and was distinguished by smaller plants, brilliant leaves, many prominent fimbriate blackish scales on stipe and rachis, long-pointed apex of lamina and pinna, halfway-lobed pinna, and narrowest pinna. Descriptions and illustrations of the two species and their photographs in the habitat are provided along with a key to the species of sect. Hirtipedes of Dryopteris in Korea.
First records of Paspalum notatum Flüggé and P. urvillei Steud. (Poaceae) in Korea
Lee, Jeongran ; Kim, Chang-Seok ; Lee, In-Yong ; Han, Young-Woo ;

DOI : 10.12651/JSR.2013.2.1.079
While collecting Poaceae weeds at Jeju-do, we found two unrecorded species of the Paspalum, P. notatum Fl
and P. urvillei Steud. We provide the descriptions and illustrations of both species. Key to the newly recorded species and related taxa of Korean Paspalum is also presented.
Age determination of the Mongolian wild ass (Equus hemionus Pallas, 1775) by the dentition patterns and annual lines in the tooth cementum
Lkhagvasuren, Davaa ; Ansorge, Hermann ; Samiya, Ravchig ; Schafberg, Renate ; Stubbe, Anne ; Stubbe, Michael ;
Journal of Species Research, volume 2, issue 1, 2013, Pages 85~90
DOI : 10.12651/JSR.2013.2.1.085
Based on 440 skulls recently collected from two areas of the wild ass population in Mongolia, the time course of tooth eruption and replacement was investigated. The dentition pattern allows identification of age up to five years. We also conclude that annual lines in the tooth cementum can be used to determine the age in years for wild asses older than five years after longitudinal tooth sections were made with a low-speed precision saw. The first upper incisor proved to be most suitable for age determination, although the starting time of cement deposition is different between the labial and lingual sides of the tooth. The accurate age of the wild ass can be determined from the number of annual lines and the time before the first formation of the cementum at the respective side of the tooth.
Chromosomal study of the lenoks, Brachymystax (Salmoniformes, Salmonidae) from the South of the Russian Far East
Kartavtseva, I.V. ; Ginatulina, L.K. ; Nemkova, G.A. ; Shedko, S.V. ;
Journal of Species Research, volume 2, issue 1, 2013, Pages 91~98
DOI : 10.12651/JSR.2013.2.1.091
An investigation of the karyotypes of two species of the genus Brachymystax (B. lenok and B. tumensis) has been done for the Russia Primorye rivers running to the East Sea basin, and others belonging to Amur basin. Based on the analysis of two species chromosome characteristics, combined with original and literary data, four cytotypes have been described. One of these cytotypes (Cytotype I: 2n=90, NF=110-118) was the most common. This common cytotype belongs to B. tumensis from the rivers of the East Sea basin and B. lenok from the rivers of the Amur basin, i.e. extends to the zones of allopatry. In the rivers of the Amur river basin, in the zone of the sympatric habitat of two species, each taxon has karyotypes with different chromosome numbers, B. tumensis (2n=92) and B. lenok (2n=90). Because of the ability to determine a number of the chromosome arms for these two species, additional cytotype have been identified for B. tumensis: Cytotype II with 2n=92, NF=110-124 in the rivers basins of the Yellow sea and Amur river and for B. lenok three cytotypes: Cytotype I: 2n=90, NF=110 in the Amur river basin; Cytotype III with 2n=90, NF=106-126 in the Amur river basin and Cytotypes IV with 2n=92, NF=102 in the Baikal lake.
