Pristimantis lassoalcalai Barrio-Amorós, Rojas-Runjaic Barros, 2010 is a poorly known terrarana, endemic to the eastern slope of Sierra de Perijá in Venezuela. Although a close relationship of this species with Tachiramantis has been suspected based on its overall morphological similarity, this relationship had not been tested so far. On the basis of molecular data (two fragments of the 12S and 16S mtDNA genes) obtained from the type series, we reconstruct its evolutionary relationships and establish its phylogenetic position as a member of Tachiramantis. Based on this phylogenetic hypothesis, we transfer Pristimantis lassoalcalai to Tachiramantis as Tachiramantis lassoalcalai comb. nov. In addition, we describe its advertisement call. This is the fourth known species of the genus and the second to which its vocalization is described.
拉索阿尔卡莱短头蟾(Pristimantis lassoalcalai),巴里奥斯 - 阿莫罗斯、罗哈斯 - 伦贾伊克·巴罗斯于2010年发现,是一种鲜为人知的地栖蛙类,为委内瑞拉佩里哈山脉东坡的特有物种。尽管基于其整体形态相似性,曾怀疑该物种与塔奇拉短头蟾(Tachiramantis)关系密切,但这种关系迄今尚未得到验证。基于从模式标本系列中获得的分子数据(12S和16S线粒体DNA基因的两个片段),我们重建了它的进化关系,并确定其系统发育位置为塔奇拉短头蟾属的一员。基于这一系统发育假说,我们将拉索阿尔卡莱短头蟾转移至塔奇拉短头蟾属,新组合名为塔奇拉短头蟾(Tachiramantis lassoalcalai comb. nov.)。此外,我们描述了它的求偶鸣叫。这是该属已知的第四个物种,也是第二个描述了其发声的物种。
