The number of species of the subgenus Syrrhophus, genus Eleutherodactylus has increased rapidly in the last eight years, due to recent taxonomic studies. This subgenus of direct-developing frogs is well represented in Mexico, which harbors more than 90% of the species richness reported for the subgenus. In this study, we describe one new species, Eleutherodactylus (Syrrhophus) coelum sp. nov. from the El Cielo Biosphere Reserve in Tamaulipas, Mexico, based on morphological and molecular data. The new species, which was previously assigned to E. cystignathoides, differs from its congeners mainly by its small size and by having the tips of Finger III and IV expanded to twice the width of the narrowest part of these fingers. Phylogenetic analyses recovered a well-supported relationship of the new species as the sister group to an undescribed taxon from San Luis Potosí. This analysis also indicates there are more lineages wating for description.
由于近期的分类学研究，细趾蟾属（Eleutherodactylus）下的锡尔罗蟾亚属（Syrrhophus）的物种数量在过去八年中迅速增加。这种直接发育的蛙类亚属在墨西哥有很好的代表性，该国拥有该亚属所报道的物种丰富度的90%以上。在本研究中，我们基于形态学和分子数据，描述了一种来自墨西哥塔毛利帕斯州埃尔谢洛生物圈保护区的新物种——埃氏锡尔罗蟾（Eleutherodactylus (Syrrhophus) coelum sp. nov.）。该新物种之前被归为囊咽细趾蟾（E. cystignathoides），它与同属其他物种的主要区别在于体型小，以及第三和第四指的指尖扩展到这些手指最窄部分宽度的两倍。系统发育分析有力地支持了该新物种与来自圣路易斯波托西的一个未描述分类单元构成姐妹群的关系。该分析还表明，还有更多的谱系有待描述。
