Abstract：
In this work, the results of a survey for species of Fluda Peckham & Peckham, 1892 in primary forest in five Bolivian forest ecoregions are reported. Fluda dauca sp. nov. is described from Southwest Amazon forest and F. thuruampara sp. nov. from Bolivian Yungas forest. Fluda perdita (Peckham & Peckham, 1892) is reported from Bolivia for the first time. Both new species exhibited polymorphic mimicry; dark females of both species resembled the turtle ant Cephalotes pusillus (Klug, 1824) and dark males of F. thuruampara sp. nov. the carpenter ant Camponotus sanctaefidei Dalla Torre, 1892. Orange males and females of F. dauca sp. nov. are likely mimics of Camponotus latangulus Roger, 1863. Males of Fluda may compensate lower mimetic accuracy by the broadened femora I, resembling an ant head in lateral view and ant mandibles when moving the face towards a potential threat. As in other Simonellini, the turnover of Fluda species between the South American superregions suggests that significant shifts in seasonality and related conditions are major factors triggering speciation in the tribe Simonellini.
摘要：
在这项工作中,对FludaPeckham和Peckham物种的调查结果，据报道，1892年玻利维亚五个森林生态区的原始森林。Fludadaucasp.11月。来自西南亚马逊森林和F.thuruamparasp。11月。来自玻利维亚云加斯森林。Fludaperdita(Peckham&Peckham,1892）是玻利维亚首次报道的。这两个新物种都表现出多态拟态；这两个物种的深色雌性都类似于乌龟蚂蚁Cephalotespusillus（Klug，1824年）和F.thuruamparasp。11月。木匠蚂蚁CamponotussanctafideiDallaTorre,1892.橙色雄性和雌性F.daucasp.11月。很可能模仿了CamponotuslatangulusRoger,1863.Fluda雄性可能通过变宽的股骨I补偿较低的模拟准确性，在侧视中类似于蚂蚁头，在将面部移向潜在威胁时类似于蚂蚁下颌骨。和其他西蒙内里尼一样，南美超区之间Fluda物种的更替表明，季节性和相关条件的显着变化是引发西蒙内里尼部落物种形成的主要因素。
