这项研究基于2013年7月之前发表的研究，回顾了关于巴西叶蝉目的数据，估计了仍需描述的物种数量，并确定了该国哪些地区是研究最少的地区。超过一半的物种是从对一个发育阶段的描述中得知的，成虫的描述比若虫更频繁。巴西东北部是数据库最薄弱的地区。体型影响描述率，较大的物种倾向于首先被描述。到目前为止，描述的物种如此之少，这加剧了未知巴西物种的估计数量。渐近线的陡峭斜率和估计的相当大的可信区间强化了这样的结论，即仍有大量物种有待描述。这强调需要投资培训巴西所有区域的系统学和生态学专家，以纠正这些不足之处，因为已发表的论文是信息的主要来源，而且分类学知识对于制定有效措施养护短翅目动物及其赖以生存的水生生态系统至关重要。(C)2015年巴西昆虫学会。书名/作者Elsevier Editora Ltd.
This study reviewed the data on the Brazilian Ephemeroptera, based on the studies published before July, 2013, estimated the number of species still to be described, and identified which regions of the country have been the subject of least research. More than half the species are known from the description of only one developmental stage, with imagoes being described more frequently than nymphs. The Brazilian Northeast is the region with the weakest database. Body size affected description rates, with a strong tendency for the larger species to be described first. The estimated number of unknown Brazilian species was accentuated by the fact that so few species have been described so far. The steep slope of the asymptote and the considerable confidence interval of the estimate reinforce the conclusion that a large number of species are still to be described. This emphasizes the need for investments in the training of specialists in systematics and ecology for all regions of Brazil to correct these deficiencies, given the role of published papers as a primary source of information, and the fundamental importance of taxonomic knowledge for the development of effective measures for the conservation of ephemeropteran and the aquatic ecosystems they depend on.
