Abstract

Three new earthworm species of the genus Drawida Michaelsen, 1900, namely D. jatinderi Narayanan, sp. nov., D. paliwali Narayanan, sp. nov. and D. proboscidea Narayanan, sp. nov., are described from materials collected from the Kerala state of south-western India. D. jatinderi Narayanan, sp. nov., belongs to D. travancorensis Michaelsen, 1910 species group, characterized by spermathecal pores at C setal line, male pores at mid bc setal lines, glandular prostate, spermathecal atrium present, dorsal pores, and genital markings absent. Whereas D. paliwali Narayanan, sp. nov., and D. proboscidea Narayanan, sp. nov. belong to the D. robusta robusta (Bourne, 1886) group, characterized by glandular prostates and bilobed spermathecal atria. D. jatinderi Narayanan, sp. nov., and D. proboscidea Narayanan, sp. nov. were collected from the midlands of Ernakulam district, and D. paliwali Narayanan, sp. nov., was collected from the higher altitude evergreen forest of the Parambikulam Tiger Reserve of Palakkad district. Here we provide a detailed description of the external and internal characteristics of the new species, along with illustrations of the key characters. With the new findings, a total of 52 Drawida species are known from the Western Ghats biodiversity hotspot.

论印度西南部蚯蚓属 Drawida Michaelsen，1900 年的三个新种（Clitellata: Moniligastridae）。

从印度西南部喀拉拉邦采集的材料中描述了Drawida属Michaelsen, 1900年的三个新蚯蚓物种，即D. jatinderi Narayanan, sp.D. jatinderi Narayanan, sp. nov. 属于 D. travancorensis Michaelsen, 1910 物种组，其特征是精巢孔位于 C 节线，雄性孔位于 bc 节线中段，前列腺具腺，精巢房存在，背孔和生殖器斑纹缺失。而 D. paliwali Narayanan，sp. nov.和 D. proboscidea Narayanan，sp. nov.属于 D. robusta robusta（Bourne，1886 年）类，其特征是腺状前列腺和双叶精巢。D. jatinderi Narayanan（新种）和 D. proboscidea Narayanan（新种）采集自埃纳库拉姆地区的中部地区，D. paliwali Narayanan（新种）采集自帕拉卡德地区帕拉比库拉姆老虎保护区海拔较高的常绿林。我们在此详细描述了这一新种的外部和内部特征，并附有关键特征的插图。有了这些新发现，西高止山脉生物多样性热点地区已知的图拉达物种共有 52 种。

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
