Abstract

Three new species of harvestmen are described based on morphology. Taito mayoruna spec. nov. from Jenaro Herrera province, Loreto, Peru is differentiated from other species of Taito Kury Barros, 2014 by features such as anal operculum armed, and femur IV with two retro-distal spines. Taito curupira spec. nov. from Porto Velho, Rondonia, Brazil is recognized by an H-shaped color pattern, femur IV curved dorsally and armed with medial prolateral and retrolateral tubercles. A third species herein described, Eulibitia chacuamarei spec. nov., from Trinidad, Casanare, Colombia is distinguished by the absence of a ladder mask and by the presence of blunt tubercles on areas I, III and the posterior margin. Penial morphology is described, and SEM micrographs are included.

摘要

三种新的盲蛛物种基于形态学被描述。来自秘鲁洛雷托省詹纳罗·埃雷拉省的泰托·马鲁纳新种与 2014 年由库里巴罗·克吕（Kury Barros）描述的其他泰托物种不同，其特征包括肛瓣具武装，以及第四股骨具两个向后的远侧刺。来自巴西朗多尼亚州波多韦柳的泰托·库鲁皮拉新种通过 H 形的颜色模式、第四股骨背侧弯曲并具内侧前侧和后侧的结节来识别。本文描述的第三个物种，哥伦比亚卡萨纳雷省特立尼达的 Eulibitia chacuamarei 新种，其特征是没有梯形面具，以及在 I、III 区和后缘存在钝结节。描述了阴茎形态，并包括 SEM 显微照片。
