Background Neotropiella is a genus of springtails which can be of medium size (2 mm) or relatively long (5 mm). These springtails live in leaf litter, under the bark of dead trees or in decomposing wood, mainly in the Neotropical Region and are often collected by litter samples on Berlese funnels or by pitfall traps. Most species have been described, based on relatively few specimens and chaetotaxy of several species is incomplete. New information A new species within Neotropiella was discovered in recent pitfall trap collections from Peru. Neotropiella peruana sp. n. was taxonomically treated and studied under both phase contrast and scanning electron microscopy. It is similar to N. insularis from Brazil, but smaller with only 4 mandibular teeth (vs. 5) and with well-developed unguis lateral teeth. Intraspecific variation of the new species is provided. We also present the first DNA barcodes for the genus.

Neotropiella Handschin 属一新种，1942 年 (Colembola: Neanuridae) 来自秘鲁

背景 Neotropiella 是一种可以中等大小（2 毫米）或相对长（5 毫米）的弹尾虫。这些跳虫生活在落叶、枯树树皮下或腐烂的木材中，主要分布在新热带地区，通常通过伯尔塞漏斗上的垃圾样本或陷阱陷阱收集。大多数物种已经被描述，基于相对较少的标本和几个物种的毛虫学是不完整的。新信息 Neotropiella 中的一个新物种在秘鲁最近的陷阱收集中被发现。Neotropiella peruana sp. n. 在相差和扫描电子显微镜下进行分类处理和研究。它与来自巴西的岛状猪笼草相似，但更小，只有 4 颗下颌齿（对比 5 颗）和发育良好的侧齿。提供了新物种的种内变异。我们还展示了该属的第一个 DNA 条形码。
