Edaphologia, No. 103: 25–32, November 30, 2018 25 Three new earthworm species of the genus Amynthas (family Megascolecidae) from northern mountainous part of Okinawa- jima Island, Japan Yasufumi Azama1 and Kotaro Ishizuka2 13-12-55 Okita, Nago City, Okinawa, 905-0019 Japan 22-7-15 Kanayama-Cho, Higashi-kurume City, Tokyo, 203-0003 Japan Corresponding author: Yasufumi Azama ([email protected]) Received: 31 October 2017; Accepted 20 August 2018 Abstract Three new earthworm species of the genus Amynthas (Family Megascolecidae) were described from the forest area, northern part of Okinawa-jima Island. A. surculatus sp. nov. is characterized by single large circular sucker-shaped genital markings at mid-ventral line and post-setal on segments 7–8 (occasionally 6–8); scientific name refers to the large circular sucker-shaped genital marking at pre-clitellar. A. glaucus sp. nov. is characterized by thick- short figure and greenish body color; scientific name refers to greenish body color. A. cucurbitae sp. nov. is character- ized by large gourd-shaped colored patch types external markings, close to male pore; scientific name refers to the gourd-shaped external markings. Three new species are distinguishable from the other congeneric species by combina- tions of the following character status; 1) number of spermathecal pore, 2) number and situation of genital markings, 3) external markings, 4) spermathecae, 5) genital glands, 6) body size and body color. Key words: Amynthas, Megascolecidae, new species, Okinawa-jima Island keeping alive and anesthetized in water by dropping 70% Introduction ethanol. Anesthetized worms were killed by 10% formalin and To date, sixteen species of the genus Pheretima s. -

Checklist of Japanese Earthworms Updated from Easton (1981)
Checklist of Japanese Earthworms updated from Easton (1981) by R.J. Blakemore October, 2008 C/-, Soil Ecology Group, Yokohama National University, Japan. Summary The current list is about 82 valid species in seven families from Japan. Previous revisions by Easton (1981) had listed 73 or 74 species and Blakemore (2003) provisionally catalogued 76 valid earthworm taxa, with approximately 80 further names (ca. 50% of the total) either in synonymy or retained as species incertae sedis . Some 60 or so “new” Pheretima names with strange genus and species definition had been added by Ishizuka in 1999-2001 that, mostly ignorant of ICZN (1999), had but a few considered valid taxa with the majority being synonyms, homonyms [such as the permanently invalid primary homonym Pheretima montana 1999 (non Kinberg, 1867 – the type species of the genus)] or species incertae sedis and, as yet, no native Pheretima s. stricto are known from Japan. About 30 species are known introductions with four “new records” by the current author, and another ten are possibly more widespread (e.g. in Korea/China), thus the probable number of wholly endemic Japanese earthworms is around 40 species (ca. 50% of the total valid species). A subsequent report of Amynthas rodericensis (Grube, 1879) from Japan by a non-specialist is dubious and unconfirmed. However, a definitive work on the systematics of all of Japan’s earthworms is pending, relying partly on review of all of Japan’s and Korea’s classical species, and partly on more systematic on the ground eco-taxonomic surveys. While much of Easton’s synopsis is supported, Pontodrilus is now placed in Megascolecidae sensu Blakemore (2000) rather than Acanthodrilidae sensu Gates (1959); Amynthas carnosus (Goto & Hatai, 1899) is removed from synonymy of Amynthas gracilis ; and an informal Amynthas corticis species-complex is established to accommodate the various morphs of this widely distributed species group. -

The mitochondrial CO 1 gene of the Pontoscolex corethrurus (Glossoscolecidae), Travoscolides chengannures, Amynthas corticis, Perionyx sansibaricus (Megascolecidae), Progizzardus varadiamensis and Glyphidrilus annandalei (Almidae) were sequenced. The cytochrome-c oxidase I (CO1) exhibited a unique barcode to a particular species. The further exploration of mitochondrial diversity in earthworms will lead to major improvements in our understanding of the evolutionary pathways and rates of the mitochondrial genome Key words: Barcoding, cytochrome c oxidase 1 (COI), 16S ribosomal DNA INTRODUCTION DNA barcoding is a taxonomic method that uses a short genetic marker in the DNA to identify an organism. It differs from molecular phylogeny in that the main goal is to identify an unknown sample in terms of a known classification [26]. DNA sequence can be used to identify different species, in the same way as the supermarket scanner uses the black stripes of the UPC barcode to identify the items. This database will rapidly link a specimen to a Binomial Linnaean name and through that link it will provide all available information and studies on the species. -

Phylogeographic studies are useful in reconstructing the history of species inva- sions, and in some instances can elucidate cryptic diversity of invading taxa. This can help in predicting or managing the spread of invasive species. Among terrestrial invasive species in North America, earthworms can have profound ecological effects. We are familiar with the centuries-old invasions of European earthworms (Lumbricidae) and their impacts on nutrient cycling in soils. More recent invasions by Asian earthworms of the family Megascolecidae are less fully understood. We used data for two mitochondrial gene frag- ments, cytochrome oxidase I (COI) and 16S rRNA, to examine the relationships among populations of Asian earthworms in the megascolecid genus Amynthas in the northeast Uni- ted States. Recent reports have indicated that one species in particular, Amynthas agrestis, is having detrimental effects in mixed forest ecosystems, and we were interested in under- standing the invasion history for this species. We were surprised to discover three divergent mitochondrial lineages of Amynthas occurring sympatrically in upstate New York. -

The Earthworm Genus Pleionogaster (Clitellata: Megascolecidae) in Southern Luzon, Philippines
Org. Divers. Evol. 6, Electr. Suppl. 8: 1 - 20 (2006) © Gesellschaft für Biologische Systematik URL: http://www.senckenberg.de/odes/06-08.htm URN: urn:nbn:de:0028-odes0608-9 The earthworm genus Pleionogaster (Clitellata: Megascolecidae) in southern Luzon, Philippines Samuel W. James Natural History Museum and Biodiversity Research Center, Dyche Hall, 1345 Jayhawk Drive, University of Kansas, Lawrence, KS 66045, USA e-mail: [email protected] Received 2 December 2004 • Accepted 11 August 2005 Abstract An earthworm biodiversity survey of the Philippines has yielded 14 new species of the perichaetine megascolecid genus Pleionogaster, previously known from only a few species from scattered Philippine locations. Bicol, the southern peninsula of Luzon, has intact forests on several isolated volcanic peaks and other remote areas. Collections made in these forests yielded the following new species, here presented by type location: Mt. Malinao, Pleionogaster albayensis, P. bicolensis, P. castilloi, P. malinaoensis, P. tiwiensis; Mt. Isarog, P. ffitchae, P. isarogensis; Mt. Bulusan, P. bulusanensis, P. hongi, P. sorsogonensis; Catanduanes Island, P. nautsae, P. viracensis; Caramoan Peninsula, P. caramoanensis, P. nillosae. Most of the species were found only in the neighborhood of the type locality, but P. bicolensis occurs in two locations in northern Bicol. Intraspecific variation in P. castilloi was observed between northern and southern flanks of Mt. Malinao. The impor- tance of several previously overlooked Pleionogaster traits is demonstrated by their -

James (2010) Six new earthworms of the genus Pheretima (Oligochaeta: Megascolecidae) from Balbalan-Balbalasang, Kalinga Province, the Philippines. Zoological Studies 49(4): 523-533. Six new species of the genus Pheretima are described from forested lands near the village of Balbalasang in Barangay Balbalan, Kalinga Province, Luzon I., the Philippines: Pheretima kalingaensis sp. nov., Pheretima aguinaldoi sp. nov., Pheretima balbalanensis sp. nov., Pheretima banaoi sp. nov., Pheretima pugnatoris sp. nov., and Pheretima tabukensis sp. nov. Pheretima kalingaensis sp. nov. and P. aguinaldoi sp. nov. have spermathecal pores in 6/7, which are 0.09-0.16 and 0.21 circumferences apart, respectively. Pheretima balbalanensis sp. nov. and P. banaoi sp. nov. belong to the dubia-group of Sims and Easton (1972) with 3 pairs of spermathecal pores in 6/7-8/9. In P. balbalanensis sp. nov., the penis is a transverse ridge with an apical pore, but in P. banaoi sp. nov. the penis is a small elliptical bump. Pheretima pugnatoris sp. nov. and P. tabukensis sp. nov. belong to the darnleiensis-group of Sims and Easton (1972) with 4 pairs of spermathecal pores in 5/6-8/9. Pheretima pugnatoris sp. nov. has pale pigmentation, lacks septa 8/9/10, and has a typhlosole.
