Abstract

The Neotropical family Hylodidae comprises 46 currently recognized rheophilic Torrent frog species, today classified in the genera Crossodactylus, Hylodes, Megaelosia, and Phantasmarana, all endemic to the Atlantic Forest. Megaelosia and Phantasmarana are distributed along the Serra do Mar and Serra da Mantiqueira mountain ranges, southeastern Brazil, and are the least speciose genera of the family, including all the mute giant hylodids. Megaelosia is a monotypic genus, whereas Phantasmarana comprises six currently recognized species: P. apuana, P. bocainensis, P. boticariana, P. jordanensis, P. lutzae, and P. massarti. Herein, we provide a taxonomic revision of these Giant Neotropical Torrent frogs, offering a comprehensively sampled species-level molecular phylogeny. By combining molecular and morphological data, we confirm that Megaelosia and Phantasmarana are valid genera. We provide diagnostic traits for both genera, redescribe the poorly known species P. jordanensis, and describe two new species from distinct localities at Parque Estadual da Serra do Mar, P. curucutuensis sp. nov. and P. tamuia sp. nov., presenting details of adult and larval morphology, and notes on their natural history and behaviour. We further discuss systematic and taxonomic concerns, and evolutionary processes related to distribution, body sizes, and communication in the family Hylodidae. http://zoobank.org/urn:lsid:zoobank.org:pub:61EA0116-6FB9-44B8-A2CE-E99D7B887E8B http://zoobank.org/urn:lsid:zoobank.org:act:079339E6-C802-4B47-A3A3-9FA0D0FCA3D1 http://zoobank.org/urn:lsid:zoobank.org:act:0EA22628-89E9-483B-AB90-F3F0D18E28F1

揭示新热带巨型洪流蛙的多样性：系统发育关系、形态和两个新种的描述

新热带蛙科包括46种目前公认的亲流性Torrent蛙，目前分为Crossodactylus属、Hylodes属、Megaelosia属和Phantasmarana属，均为大西洋森林的特有种。Megaelosia和Phantasmarana分布在巴西东南部的Serra do Mar和Serra da Mantiqueira山脉，是该科物种最少的属，包括所有的静音巨型hylodids。Megaelosia是一个单型属，而Phantasmarana包括六个目前公认的物种：P.apuana、P.bocainensis、P.boticariana、P.jordanensis、P.lutzae和P.massarti。在此，我们对这些巨型新热带洪流蛙进行了分类修订，提供了一个全面的物种级分子系统发育样本。通过结合分子和形态学数据，我们确认Megaelosia和Phantasmarana是有效的属。我们提供了这两个属的诊断特征，重新描述了鲜为人知的约丹P.jordanensis，并描述了来自Parque Estadial da Serra do Mar不同地区的两个新物种，P.curucutuensis sp.nov.和P.tamuia sp.nov..，介绍了成虫和幼虫形态的细节，并对它们的自然历史和行为进行了说明。我们进一步讨论了海狗科的系统和分类学问题，以及与分布、体型和交流有关的进化过程。http://zoobank.org/urn:lsid:zoobank.org:pub:61EA0116-6FB9-44B8-A2CE-E99D7B887E8Bhttp://zoobank.org/urn:lsid:zoobank.org:act:079339E6-C802-4B47-A3A3-9FA0D0FCA3D1http://zoobank.org/urn:lsid:zoobank.org:act:0EA22628-89E9-483B-AB90-F3F0D18E28F1

期刊介绍： Systematics and Biodiversity is devoted to whole-organism biology. It is a quarterly, international, peer-reviewed, life science journal, without page charges, which is published by Taylor & Francis for The Natural History Museum, London. The criterion for publication is scientific merit. Systematics and Biodiversity documents the diversity of organisms in all natural phyla, through taxonomic papers that have a broad context (not single species descriptions), while also addressing topical issues relating to biological collections, and the principles of systematics. It particularly emphasises the importance and multi-disciplinary significance of systematics, with contributions which address the implications of other fields for systematics, or which advance our understanding of other fields through taxonomic knowledge, especially in relation to the nature, origins, and conservation of biodiversity, at all taxonomic levels. The journal does not publish single species descriptions, monographs or applied research nor alpha species descriptions. Taxonomic manuscripts must include modern methods such as cladistics or phylogenetic analysis.
