Data from: A new tuberculated Pristimantis (Anura, Terrarana, Strabomantidae) from the Venezuelan Andes, redescription of Pristimantis pleurostriatus, and variation within Pristimantis vanadisae

A new tuberculated Pristimantis is described from the eastern versant of the Venezuelan Andes. The new species is found in cloud forest at around 1600 masl on the eastern side of the Cordillera de Mérida. It is distinguished from other similar tuberculated species by its round, ill-defined canthus rostralis, ill-defined canthal stripe, and absence of pale spots on the groin and posterior surface of thighs. Pristimantis pleurostriatus is a poorly known species found in cloud forest on the western slopes of the Venezuelan Andes. We redescribe the species based on topotypic specimens. Pristimantis vanadisae is a polychomatic species varying dramatically in pattern; four chromotypes are described. Molecular data are presented which distinguish among tuberculated and other species of Pristimantis in the Cordillera de Merida. Molecular data also support placement of Mucubatrachus and Paramophrynella in Pristimantis.本研究记述了一种采自委内瑞拉安第斯山脉东坡的具疣突棱蟾属（Pristimantis）新种。该新种分布于梅里达山脉东侧海拔约1600米（meters above sea level，masl）的云雾林生境中。该种可通过以下特征与其他具疣突的近缘棱蟾属物种相区分：其吻棱圆润且界限模糊、吻棱纹边界不清，且腹股沟区与大腿后表面无浅色斑点。侧纹棱蟾（Pristimantis pleurostriatus）是一种研究程度较低的物种，栖息于委内瑞拉安第斯山脉西坡的云雾林生境中，本研究基于其模式产地标本对该物种进行了重新记述。瓦纳达棱蟾（Pristimantis vanadisae）为多色型物种，体色花纹差异显著，本研究共记述了四种色型。本研究提供的分子数据可区分梅里达山脉内具疣突的棱蟾属物种与其他近缘类群，同时支持将穆库巴蟾属（Mucubatrachus）与副滑蟾属（Paramophrynella）归入棱蟾属（Pristimantis）。
