Abstract

Abstract: We described a new species of Dendrophryniscus from the Mantiqueira Mountains, a mountain range in the Atlantic Forest in the state of Minas Gerais, Brazil. Dendrophryniscus cuca sp. nov. is known only from its type locality, the private Protected Area Chapada͂o da Serra Negra, municipality of Santa Bárbara do Monte Verde. The new species is morphologically distinguished from its congeners mainly by the combination of the following characters: medium size for the genus, longitudinal set of granules posterior to the corner of mouth, fingers neither fringed nor webbed, and presence of nuptial pads in males. Molecular analysis of the 16S mitochondrial DNA indicates a genetic distance range from 2.39% (D. brevipollicatus) to 17.92% (D. carvalhoi). Individuals were found in bromeliads, and we described a male–male amplexus with the presence of release vibrations, but calling activity was not observed. This is the fourth endemic anuran species of the Serra Negra da Mantiqueira, part of the Mantiqueira mountain range (Serra Negra da Mantiqueira), highlighting the importance of the region for the Neotropical herpetofauna.

巴西米纳斯吉拉斯州Mantiqueira山Dendrophryniscus jim nez de la Espada 1871一新种(两栖纲:无尾目:蟾蜍科)

摘要：我们报道了一种产于巴西米纳斯吉拉斯州大西洋森林山脉曼蒂奎拉山脉的石斛属新种。Dendrophrynisus cuca sp.nov.仅从其类型地区，即圣巴巴拉-蒙特维德市的私人保护区Chapada͂o da Serra Negra已知。该新种在形态上与同类物种的区别主要在于以下特征的组合：该属中等大小，嘴角后有一组纵向颗粒，手指既没有流苏也没有网状，雄性有婚垫。16S线粒体DNA的分子分析表明，遗传距离在2.39%（D.brevipollicatus）到17.92%（D.carvalhoi）之间。在凤梨科植物中发现了个体，我们描述了一种存在释放振动的雄性-雄性金龟子，但没有观察到呼叫活动。这是曼蒂奎拉山脉（Serra Negra da Mantiqueira）的第四个特有的无尾类物种，突出了该地区对新热带爬行动物的重要性。
