Abstract

Abstract: The bromeligenous genus Crossodactylodes, endemic to the Atlantic Forest domain and the “campo rupestre” ecosystem in Brazil, currently comprises five named species. Three additional putatively new species have already been proposed in a recent study based on mitochondrial and nuclear markers. Here we employ phenotypic data to corroborate the distinctiveness of one of these lineages, and describe it as a new species, from the Espinhaço Mountain Range in the municipality of Itamarandiba, state of Minas Gerais, southeastern Brazil. We also provide information on its natural history and conservation status. The new species is diagnosable from its congeners by a combination of characters, including the presence of vocal slits in adult males, the orange coloration of discs on fingers and toes, and the presence of vomerine odontophores. The new species is the second Crossodactylodes to be reported for the campo rupestre and it was only recorded in a small forest patch composed of low trees, shrubs, mosses, lichens, and a high density of bromeliads.

巴西东南部Espinhaço山脉交叉偶蹄目一新种（无尾目：细偶蹄目：Paratelmatobiinae）

摘要/ Abstract摘要:凤梨属Crossodactylodes是大西洋森林域和巴西“campo rupestre”生态系统的特有种，目前有5个已命名种。最近一项基于线粒体和核标记的研究已经提出了另外三个假定的新物种。在这里，我们利用表型数据来证实其中一个谱系的独特性，并将其描述为一个新物种，来自巴西东南部米纳斯吉拉斯州伊塔马兰迪巴市的埃斯帕纳帕拉多山脉。我们还提供了有关其自然历史和保护状况的信息。这个新物种可以通过一系列特征从它的同系物中诊断出来，这些特征包括成年雄性的声缝，手指和脚趾上的圆盘呈橙色，以及下颌赘肉的存在。该新种是报道的第二种交叉趾属植物，仅在由低矮乔木、灌木、苔藓、地衣和高密度凤梨科植物组成的小片森林中发现。
