Abstract

Surveys of easily accessible or moderately remote South Korean mountains has revealed several common exotic and early species-complexes [Amynthas corticis (Kinberg, 1867) with A. diffringens (Baird, 1869), A. gracilis (Kinberg, 1867) and Metaphire californica (Kinberg, 1867)], plus an unexpected number of new native taxa. Megascolecid Metaphire muuido sp. nov. and lumbricid Eisenia muuido sp. nov. are newly described from Muuido Island, Incheon. Montane taxa are parthenogenetic Amynthas tokioensis oculo sub-sp. nov. that lacks male pores but is yet comparable to both Amynthas tokioensis (Beddard, 1892) and Metaphire soulensis (Kobayashi, 1938) with its possible new synonym A. chiakensis Hong & James, 2013. Apparently unique sympatric taxa are Amynthas bangtaesan bangtaesan and A. b. confinius sup-spp. nov., Amynthas centurio sp. nov., Amynthas punicans sp. nov., Amynthas seoraksan and A. seoraksan iti sub-spp. nov. These are newly described and their DNA COI gene barcodes, where obtainable, are presented in a phylogram with outgroup Acanthodrilidae Microscolex dubius (Fletcher, 1887) from Lake Biwa Japan being a new exotic record for Asia.
