농생태계 시설 재배지와 과수원에서 서식하고 있는 지렁이상을 확인하였는데 채집된 지렁이는 시설 재배지에서 3과 5속 11종, 과수원에서 채집된 지렁이는 3과 4속 12종으로 다음과 같다 공통적으로 채집된 종은 Aporrectodea tuberculata, Eisenia fetida, Eisenia andrei, Amynthas hupeiensis, Amynthas heteropodus, Amynthas koreanus, Amynthas agrestis, Amynthas hilgendorfi, Amynthas sp., Drawida japonica이다. 시설 재배지에서만 채집된 종은 Bimastos parvus이고, 과수원에서만 채집된 종은 Aporrectodea caliginosa, Amynthas corticis이다. 조사지역내 토양의 물리적 환경에서 유기물 함량은 시설 재배지에서 많은 편차를 보였으나 과수원에서는 비교적 비슷한 경향을 보였다. 경작 단계 별에서 채집된 종수와 개체수는 유기합성농약을 사용하지 않은 무능약과 유기농단계에서 가장 많이 나타났다. 전국적인 농생태계 지렁이 개체군 조사에서 우점군으로 밝혀진 Amynthas agrestis보다 두 지역 모두 Amynthas heteropodus가 가장 많이 출현하였는데 유기합성농약을 사용한 재배지보다 사용하지 않은 재배지에서 많이 출현하였다. 본 연구 결과 Amynthas heteropodus가 작물재배지의 농생태계 생물지표 후보종으로 사용할 수 있음을 확인하였는데. 비교적 이 종은 외부 형태적 형질로 안정되게 나타난다.

지렁이과 (family Megascolecidae) 왕지렁이속 (genus Amynthas) 그룹을 rDNA ITS 유전자를 이용하여 계통 유연관계를 알아보고자 하였다. 2과 10속에서 26종의 DNA 염기서열을 이용하여 종간 계통적 유연관계를 MP (Maximum Parsimony), NJ (Neighbor Joining), QP (Quartet Puzzling)로 계통도를 작성하였다. 염기서열이 확보된 Megascolecidae (지렁이과)의 국내외 26종에 대한 계통 분석은 위 3개의 알고리즘 모두 동일한 5개의 그룹으로 나뉘는 것을 확인하였다. 또한 Amynthas 속은 크게 한국산 그룹과 필리핀산 그룹으로 구분되었다. 첫 번째 그룹, Amynthas jirensis, A. agrestis, A. gucheonensis, A. sopaikensis, A. bubonis, A. multimaculatus, A. koreanus, A. dageletensis, A. heteropodus, A. odaesanensis, Pontoscolex sp., Pheretima sp. 1와 다른 그룹, Dendropheretima banahawensis. Amynthas halconensis, A. isarogensis, A. mindrooensis, Pithemera sp. 2, Pithmera sp. 1, and Pleionogaster sp.이다. 이는 ITS 유전자가 속간의 차이를 보여주는 것보다 동일한 속이라 하더라도 지리적 차이에 따른 환경의 영향을 받았음을 알 수 있다. 즉 형태적 분화가 이루어졌다고 하더라도 유전적으로는 동질성을 나타내고 있음을 알 수 있다. 형태적 특징에 의한 명백한 차이는 구분되지 않았다.

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.

An earthworm survey of Busan metropolitan area unearthed a dozen taxa in four families (including Enchytraeidae). Members of mostly common, cosmopolitan earthworm species-complexes were: Drawida cf. koreana Kobayashi, 1938, Amynthas cf. corticis (Kinberg, 1867), Aporrectodea trapezoides (Dug$\grave{e}$s, 1828) and Eisenia fetida (Savigny, 1826). Also found were Amynthas hupeiensis (Michaelsen, 1895), A. masatakae (Beddard, 1892) and Metaphire ryunome Blakemore, 2012 - the latter a new Korean record. New taxa are: moniligastrid Drawida songae yeongdo subsp. n.; megascolecid Amynthas carnosus roki subsp. n. which is compared to nominal taxon A. carnosus (Goto and Hatai, 1899) from Japan, to A. carnosus monstriferus (Kobayashi, 1936) stat. n. from Korea and to A. lichuanensis Wang and Qiu, 2005 stat. n. from China; plus lumbricid Eisenia japonica vaga subsp. n. deemed an objectively-based molecular taxon on its unique DNA COI gene barcode. Restoration of Eisenia xanthurus (Templeton, 1836) for E. andrei is mooted (in Appendix).

Japanese/Korean Amynthas carnosus (Goto & Hatai, 1899) is redescribed from a newly designated Neotype (Tokyo NSMT An435). An annotated synonymy is presented that nominally includes: kyamikia Kobayashi, 1934, monstrifera Kobayashi, 1936, sangyeoli, youngtai, kimhaeiensis, sinsiensis and baemsagolensis - all Korean names by Hong & James, 2001, and Taiwanese monsoonus James et al., 2005. However, Chinese A. pingi (Stephenson 1925) (syn. fornicata Gates, 1935) is maintained separately, at least for the present, until its comprehensive review, possibly extending to DNA barcode differentiation.

Amynthas diffringens (Baird, 1869) is deemed valid yet comparable to A. corticis (Kinberg, 1867) and to A. nipponicus (Beddard, 1893) or A. peregrinus (Fletcher, 1896). Its syntypes tend to more genital markings than usual as shown for variable specimens from Japan, Korea, and Australasia that comply genetically with either of two A. corticis spp. groups. A. diffringens type-locality was UK hothouses yet closest specimens appear in part of A. heteropodus (Goto & Hatai, 1899) (=A. corticis) from Japan. Japanese Amynthas divergens (Michaelsen, 1892) is restored based on its serrate intestinal caeca. Meanwhile, the lectotype of Amynthas pingi (Stephenson, 1925) is deemed a synonym of A. carnosus (Goto & Hatai, 1899) compliant with Kobayashi's (1936) types III & II. Erstwhile A. pingi synonym A. fornicatus (Gates, 1925) is again included, but A. hongkongensis (Michaelsen, 1910) and A. chungkingensis (Chen, 1936) are provisionally retained whilst A. carnosa lichuanensis Wang & Qiu, 2005 is given separate species status. A new Korean taxon is proposed as A. carnosus naribunji sub-sp. nov. and two replacement names are provided: A. zhuya nom. nov. for homonym A. montanus Qiu & Sun, 2012 from Hainan and A. yizhou for A. carnosus sensu Shen et al., 2005 from Taiwan. No attempt is made to fully resolve numerous Japanese synonyms of A. carnosus [eg Ishizuka's (2001) invista, subterranea, subalpina, umbrosa, mutabilis, nubicola, plus A. nonmonticolus Blakemore, 2010] nor Korean synonyms [eg kyamikia Kobayashi, 1934, monstrifera Kobayashi, 1936 and murayamai Kobayashi, 1938, sangyeoli, youngtai (with segments miscounted), kimhaeiensis, sinsiensis and baemsagolensis - all names by Hong & James (2001) plus ?A. sangumburi Hong & Kim, 2002 (its segments miscounted too)] also A. fuscus Qiu & Sun, 2012 from Hainan and Taiwanese monsoonus James et al., 2005 plus A. penpuensis Shen et al., 2003 and A. taiwumontis Shen et al., 2013 syns. nov.. All synonyms remain in the currently defined A. carnosus pending full revisons although several may eventually comply with parts of prior A. corticis s. lato.

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.
