Earthworm specimens collected in southern Taiwan consisted of seven new species of Amynthas and several previously known species, mostly widely distributed peregrines. The new species are A. nanrenensis of the octothecal A. corticis species group, A. monsoonus and A. huangi of the sexthecal A. aelianus species group, and four proandric octothecal species: A. chaishanensis, A. hengchunensis, A. kaopingensis and A. ailiaoensis. Amynthas chaishanensis has dorsal intrasegmental spermathecal pores, but the other three proandric species have dorsal, lateral or ventral intersegmental spermathecal pores, respectively. The proandric species are united by several features, including the enclosure of segment xi in a sac, as in A. formosae (also proandric), octothecal with spermathecae in vi–ix, spermathecal diverticula stalks generally kinked and often enclosed in membrane, and prostatic ducts divided polytomously into numerous small ductlets, which may be grouped into bundles of two to five. In A. ailiaoensis the prostatic duct trunk contains up to seven separate lumens in the ental half, surrounded by the circular muscle of the duct, while in A. chaishanensis the prostatic duct trunk contains about 40 small lumens. Of the previously known species in the collection, Pontodrilus litoralis and Metaphire houlleti are first reported from Taiwan. Additional locations for A. incongruus and A. robustus are given, and in the latter case the material appears to be the usual male‐sterile morph. Other species found are Pontoscolex corethrurus, Amynthas corticis, A. gracilis, Metaphire californica, and Polypheretima elongata.  相似文献

This paper describes four new species of earthworms from Hainan Island, China: Amynthas obsoletus sp. nov., Amynthas dorsualis sp. nov., Amynthas mirifius sp. nov. and Amynthas pulvinus sp. nov. Amynthas obsoletus is an athecate earthworm, has greyish or brownish pigment on the dorsum, and has two genital papillae beside each male pore, one medial and one anterior, three genital papillae arranged transversely in VIII, prostates in XVII–XX. Amynthas dorsualis, Amynthas mirifius and Amynthas pulvinus are all octothecate earthworms, and key to the corticis-group, but the spermathecal pores are located on the dorsum in Amynthas dorsualis. Amynthas dorsualis has dark grey and dark brown pigment on the dorsum, an annular clitellum in 1/10XIV–7/10XVI, and lacks genital markings. Amynthas mirifius and Amynthas pulvinus both have four pairs of spermathecal pores on the ventrum. Amynthas mirifius has four peanut-in-shell-shaped genital markings, which are rectangular with enlarged rounded ends, between the two male pores, while Amynthas pulvinus has a large glandular rounded rectangle-shaped genital marking on the ventral side of 17/18–18/19. DNA barcodes are provided for the last two new species collected in 2011, and have been submitted to NCBI to enable molecular species identification. http://www.zoobank.org/urn:lsid:zoobank.org:pub:27AD7191-5438-4F10-B177-5FCCA893A2EB  相似文献

Four new earthworm species of the genus Amynthas are described from Hainan Island, China. They are Amynthas endophilus sp. nov., Amynthas fluviatilis sp. nov., Amynthas fucatus sp. nov. and Amynthas apapillatus sp. nov. Amynthas apapillatus sp. nov. has three spermathecal pores in 6/7–8/9 while the other three new species have two pairs of spermathecal pores in 5/6–6/7. Their anatomical and morphological characteristics are compared to similar species from Hainan Island, China mainland and South-East Asia. Furthermore, COI and 16S gene sequences of these new species are submitted to NCBI. http://www.zoobank.org/urn:lsid:zoobank.org:pub:33B61DE5-BE64-47E9-B77C-D6234D25803B  相似文献

Two new species of the genus Amynthas are described from Mt Jiri (Korea): Amynthas baikmudongensis sp. nov., and Amynthas cheonghakdongensis sp. nov. The species A. baikmudongensis sp. nov. has two pairs of spermathecal pores in intersegments 5/6/7; large circular-shaped raised pads extending from 17/18, 18/19 with transverse grooves extending from approximately the centres of the pads towards the presetal half of the pad. The others species, A. cheonghakdongensis sp. nov., has two pairs of spermathecal pores in intersegments 6/7/8; and circular male porophores extending from 17/18 to 18/19.

This paper describes four new species of earthworms, Amynthas shinanmontis sp. nov., Amynthas chilanensis sp. nov., Amynthas bilineatus sp. nov., and Amynthas cruxus sp. nov. from Taiwan. Amynthas shinanmontis is sexthecate and parthenogenetic with individuals with various levels of degeneration of spermathecae and male reproductive organs. It occurs at elevations of 1700–2700 m in the Central Mountain Range in southern Taiwan. Amynthas bilineatus and A. chilanensis are athecate and also parthenogenetic. They occur, respectively, at elevations of 1000 m in the central region and 1325 m in the northeastern region of Taiwan. Amynthas cruxus is octothecate, amphimictic, and occurs at elevations of 900–1700 m in southern Taiwan. This paper also discusses confusion and dilemma caused by uncertain, speculative synonyms and parthenogenetic morphs in species delimitation in oligochaete taxonomy, and recommends the use of absolute synonyms and phylogenetic species concept.  相似文献
