尽管历史上的努力，列出和组织的分类知识，巴西蚂蚁动物群，在世界上最多样化的物种分布数据和采样覆盖率方面的几个差距仍然存在。为了填补这些空白，我们在这里采用科学计量的方法，提供一个更新的概述，巴西蚂蚁的基础上，在巴西领土上的蚂蚁多样性的正式出版物。在过去的50年里，巴西的蚂蚁多样性研究揭示了1130种，相当于该国已知物种的70%左右。记录到的物种数量最多的巴西生物群落分别是亚马逊森林（716种）、大西洋森林（657种）、塞拉多（389种）、卡廷加（185种）、潘塔纳尔（143种）和潘帕（86种）。考虑到未识别物种的数量和频率，属阿兹特克，Hypoponera，Pheidole，和Solenopsis代表了关于分类分辨率的主要知识前沿，其80%以上的记录与形态种代码在巴西的多样性研究。此外，大约7.5%的论文在其物种列表中提出了关于分类名称有效性的不一致性，我们发现一些分类群记录在地理上是不可信的。除了证明生态出版物在巴西的蚂蚁多样性知识的重要性，我们的研究结果强调了在该国的蚂蚁发生数据的强有力的抽样偏差，与物种记录不均匀分布在巴西生物群系。总之，我们的研究结果构成了宝贵的信息，为未来的项目蚂蚁分类和调查在巴西的自然区域。
Despite the historical efforts to list and organize the taxonomic knowledge about the Brazilian ant fauna, the most diverse in the world, several gaps regarding species distribution data and sampling coverage persist. In an attempt to fill some of these gaps, we here apply a scientometric approach to provide an updated overview of the ants of Brazil based on formal publications on ant diversity in the Brazilian territory. In the last 50 years, ant diversity studies in Brazil revealed 1130 species, corresponding to around 70% of the species known to occur in the country. The Brazilian biomes with the highest number of described species recorded were, respectively, the Amazon Forest (716 species), Atlantic Forest (657 species), Cerrado (389 species), Caatinga (185 species), Pantanal (143 species), and Pampa (86 species). Considering the number and frequency of unidentified species, the genera Azteca, Hypoponera, Pheidole, and Solenopsis represent the main knowledge frontiers regarding taxonomic resolution, with more than 80% of their records associated with morphospecies codes in diversity studies in Brazil. Moreover, around 7.5% of the papers presented inconsistences in their species lists regarding the validity of taxonomic names, and we found studies for which some taxa records are geographically implausible. Besides demonstrating the importance of ecological publications to the ant diversity knowledge in Brazil, our findings highlight a strong sampling bias in ant occurrence data in the country, with species records unevenly distributed across Brazilian biomes. In short, our results constitute valuable information for future projects on ant taxonomy and surveying in Brazilian natural areas.
