Three new species of the genus Misionella are described from Brazil: Misionella carajas sp. n. and Misionella aikewara sp. n. from caves in the states of Pará and Tocantins and Misionella pallida sp. n. from natural and synanthropic dry areas in the states of Piauí, Maranhão, Rio Grande do Norte and Bahia. These species seem to belong to a distinct group within the genus; the males have an elongate palpal tibia and bulb, a pair of characteristic and hirsute macrosetae in the second metatarsus and the females have internal genitalia with only one pair of spermathecae, with relatively short ducts, lacking the auxiliary receptacles. Their phylogenetic placement and geographic distribution are briefly discussed.
来自帕拉州和托坎廷斯州洞穴的卡拉雅斯米西奥内拉新种(Misionella carajas sp. n.)和艾克瓦拉米西奥内拉新种(Misionella aikewara sp. n.),以及来自皮奥伊州、马拉尼昂州、北里奥格兰德州和巴伊亚州自然及人类聚居干旱地区的苍白米西奥内拉新种(Misionella pallida sp. n.)。这些物种似乎属于该属内一个独特的类群;雄性具有细长的触肢胫节和触肢球,第二跗节有一对具特征性且多毛的大刚毛,雌性具有仅一对受精囊的内生殖器,受精囊导管相对较短,缺少辅助受精囊。简要讨论了它们的系统发育位置和地理分布。
