Abstract

Abstract: We review the taxonomic status of Oligodon arnensis (Shaw 1802) after examining all the name-bearing types of its synonyms, and evaluating morphological and biogeographic evidence. Oligodon arnensis sensu lato is widely distributed throughout Peninsular India, Sri Lanka, Pakistan, Nepal, Bhutan, and Bangladesh. We demonstrate that southern, eastern, and western populations in India represent three distinct species. Oligodon arnensis sensu stricto described from Arnee (now Arani), Tamil Nadu, southern India, is distributed in southern India up to 1500 m above sea level. Oligodon albiventer Günther 1864 and Simotes russellii var. ceylonensis Müller 1887 described from Sri Lanka closely match O. arnensis sensu stricto, and hence we treat them as junior synonyms. We resurrect Coluber russelius Daudin 1803 from the synonymy of O. arnensis, designate a lectotype, and restrict its type locality to Vizagapatam (now Visakhapatnam), Andhra Pradesh, eastern Peninsular India. Based on morphological differences we describe a new species from Kurduvadi, in the Deccan plateau of western India representing the western Indian population of O. arnensis sensu lato. We provide redescriptions for O. arnensis sensu stricto and O. russelius comb. nov. based on museum specimens, as both were named based on illustrations (iconotypes). Based on our update of the currently confirmed localities for O. arnensis, O. russelius comb. nov. and the new species, we discuss their biogeography and conservation status.

阿氏寡齿藻（Shaw1802）物种复合体的分类组成（角鲨目：珊瑚科）及印度一新种记述

摘要：我们在对其同义词的所有命名类型进行检查，并对形态学和生物地理学证据进行评估后，综述了Oligodon arnensis（Shaw 1802）的分类地位。阿氏寡齿龙广泛分布于印度半岛、斯里兰卡、巴基斯坦、尼泊尔、不丹和孟加拉国。我们证明，印度南部、东部和西部的种群代表了三个不同的物种。来自印度南部泰米尔纳德邦Arnee（现在的Arani）的阿氏寡齿龙（Oligodon arnensis sense stricto）分布在印度南部海拔1500米的地区。来自斯里兰卡的Oligodon albiventer Günther 1864和Simotes russelii var.ceylonensis Müller 1887与严格意义上的O.arnensis非常吻合，因此我们将它们视为初级同义词。我们从O.arnensis的同义词中复活了Coluber russelius Daudin 1803，指定了一个选型，并将其类型位置限制在印度半岛东部安得拉邦的Vizagapatam（现在的Visakhapatnam）。基于形态差异，我们描述了一个来自印度西部德干高原库尔杜瓦迪的新种，代表了印度西部的O.arnensis sensu lato种群。我们提供了严格意义上的O.arnensis和O.russelius梳的重新描述。nov.基于博物馆标本，因为两者都是根据插图（图像类型）命名的。根据我们目前确认的O.arnensis、O.russelius comb的最新位置。nov.和新物种，我们讨论了它们的生物地理学和保护状况。
