Bretfeld is a small genus of Neotropical Bourletiellidae, with only four described species so far. Yosii is a widespread taxon of Dicyrtomidae, with most species known from the tropics. Here, we describe two new species from northeastern Brazil: sp. nov. and sp. nov. We also provide a detailed chaetotaxic study for for the first time, with updated diagnoses and identification keys for the Neotropical species of both genera and notes on their morphology. sp. nov. resembles Arlé in body color pattern, male head and dental chaetotaxy. The discovery of one bothriotrichum-like sens on the large abdomen of the new species needs to be investigated as a possible generic diagnostic feature, but we suggest that this structure is homologous to the S-sens seen in at least four Bourletiellinae genera, and they are likely related to each other. sp. nov. belongs to the -group and resembles Reuter and Nayrolles and Betsch in some aspects of the head, dental and abdominal chaetotaxy. These descriptions represent the first record of from Caatinga and the first nominal species of from Brazil.
布雷特费尔德属是新热带区布尔莱蒂叶甲科的一个小属，迄今为止仅描述了4个物种。约西属是双角跳虫科一个分布广泛的分类单元，大多数物种分布于热带地区。在此，我们描述了来自巴西东北部的两个新物种：新种1和新种2。我们还首次对新种1进行了详细的刚毛序研究，并更新了这两个属的新热带物种的诊断和鉴定检索表，以及关于它们形态的注释。新种1在体色模式、雄性头部和齿部刚毛序方面与阿尔莱属相似。新物种大腹部上发现的一种类似双毛感器需要作为一种可能的属级诊断特征进行研究，但我们认为这种结构与至少四个布尔莱蒂叶甲亚科属中所见的S感器同源，它们可能彼此相关。新种2属于某一组，在头部、齿部和腹部刚毛序的某些方面与罗伊特属以及纳罗勒斯和贝奇属相似。这些描述代表了来自卡廷加地区的新种1的首次记录以及来自巴西的新种2的首个命名物种记录。
