We describe a new Pristimantis species from the eastern Andes, Región Junín, Peru following an integrative taxonomic approach. The description is based on three adult males (snout-vent length 25.7–28.8 mm) collected in two montane forests between 1615 and 1800 m a.s.l. in the Pui Pui Protected Forest and its close surroundings. The new species is mainly characterised by absence of tympanum, presence of inner tarsal fold, broad horizontal red band across iris, ventre mottled black and cream and ventral surfaces of thighs salmon and grey mottled. Amongst the Amazonian and montane forest Pristimantis that have the ventre and groin contrastingly black and cream mottled, P. sinschisp. nov. is morphologically most similar to P. lindae and P. ventrimarmoratus. However, DNA barcoding revealed a clear distinction between these three species and placed P. sinschisp. nov. as sister taxon of P. lindae. We designate a lectotype for P. ventrimarmoratus and restrict the type locality of this species to “El Topo, R. Pastaza, [Provincia Tungurahua,] E. Ecuador, 4200 feet”. Pristimantis albertus and P. sagittulus are recorded for the first time in the Región Junín. Additional data on morphology and systematics are provided for P. albertus.

贝贝保护森林（秘鲁中部）的一种新的Pristimantis（两栖类，阿努拉，Strabomantidae），并附有关于Pristimantis albertus Duellman＆Hedges的评论，2007年

我们采用整合的分类学方法，描述了来自秘鲁安第斯山脉地区的一个新的Pristimantis物种。描述是基于三只成年雄性动物（鼻孔长25.7–28.8毫米），它们收集于1615年至1800 m升的贝鲁保护林及其附近的两个山地森林中。新物种的主要特征是没有鼓膜，内部有睑板褶，虹膜上有宽的水平红色条带，腹斑呈黑色和乳白色斑纹，以及大腿鲑和灰斑驳的腹面。在亚马孙和山地森林Pristimantis中，腹泻和腹股沟呈黑色和奶油状斑驳，P。sinschisp。十一月 在形态上与P. lindae和P. ventrimarmoratus最相似。但是，DNA条形码揭示了这三个物种与放置的P之间的明显区别。sinschisp。十一月 作为P. lindae的姐妹分类单元。我们指定了P. ventrimarmoratus的选型，并将该物种的类型限定为“ El Topo，R。Pastaza，[Provincia Tungurahua，] E. Ecuador，4200英尺”。Pristimantis albertus和P. sagittulus在RegiónJunín中首次被记录。提供了有关形态学和系统学的其他数据。
