The soft tick Ornithodoros guaporensis n. sp. (Acari: Ixodida: Argasidae) is described from larvae and adults. Morphological analysis and 16S rDNA sequences are provided. Adults were collected from a rocky fissure inhabited by bats located in the Amazonian forest in north-eastern Bolivia (Beni Department) close to the Guapord River. Larvae were obtained from eggs laid by females collected in the field, and which were fed on rabbits in the laboratory. Larvae of O. guaporensis are morphologically closely related to Ornithodoros rioplatensis, Ornithodoros puertoricensis and Ornithodoros talaje. Larvae of O. guaporensis and O. rioplatensis can be separated from O. puertoricensis and O. talaje by the number of pairs of dorsal setae (20 in O. guaporensis and O. rioplatensis, 18 in O. puertoricensis and 17 in O. talaje). Larvae of O. guaporensis and O. rioplatensis can be differentiated by the medial dental formula (2/2 in O. guaporensis and 3/3 in O. rioplatensis) and the apex of the hypostome, which is more pointed in O. rioplatensis than in O. guaporensis. The Principal Component Analysis performed with morphometric characters of larvae showed a clear separation among O. guaporensis, O. rioplatensis, O. puertoricensis and O. talaje. Significant morphological differences among adults of these four species were not found. The analysis of the 16S rDNA sequences allowed for the differentiation between O. guaporensis and the remaining Neotropical species of the family Argasidae.
软蜱瓜波雷多罗蜱新种（蜱螨亚纲：硬蜱目：argasidae）的幼虫和成虫被描述。提供了形态学分析和16S rDNA序列。成虫采自玻利维亚东北部（贝尼省）靠近瓜波德河的亚马逊森林中蝙蝠栖息的岩石裂缝。幼虫是从野外采集的雌性所产的卵中获得的，并在实验室中用兔子喂养。瓜波雷多罗蜱的幼虫在形态上与里奥普拉特罗蜱、波多黎各罗蜱和塔拉杰罗蜱密切相关。瓜波雷多罗蜱和里奥普拉特罗蜱的幼虫可以通过背毛对数与波多黎各罗蜱和塔拉杰罗蜱区分开来（瓜波雷多罗蜱和里奥普拉特罗蜱有20对，波多黎各罗蜱有18对，塔拉杰罗蜱有17对）。瓜波雷多罗蜱和里奥普拉特罗蜱的幼虫可以通过中齿公式（瓜波雷多罗蜱为2/2，里奥普拉特罗蜱为3/3）和下咽顶端来区分，里奥普拉特罗蜱的下咽顶端比瓜波雷多罗蜱更尖。对幼虫形态特征进行的主成分分析表明，瓜波雷多罗蜱、里奥普拉特罗蜱、波多黎各罗蜱和塔拉杰罗蜱之间有明显的区分。在这四个物种的成虫之间未发现显著的形态差异。对16S rDNA序列的分析使得瓜波雷多罗蜱与argasidae科其余新热带物种得以区分。
