保护生物多样性需要找到最多样化的地点。物种水平是最常考虑的分类分辨率。然而，这是几乎不可能进行快速物种水平的调查，许多高度多样性和难以识别的类群，主要是在节肢动物，这是物种丰富度的主要组成部分。我测试了是否较高的类群（属和科）是很好的代理物种丰富度在三个大的，通常不调查组在匈牙利中部的16个储备：鞘翅目（2415种），双翅目（1004种），和阿卡里（288种）。保护区的物种丰富度与所有类群的属和科多样性密切相关。物种数也相关的三个类群对之间，但不属和科数。因此，较高的分类单元多样性是物种多样性的良好替代，但一个分类单元的多样性只能在物种水平上指示另一个分类单元的多样性。
The conservation of biodiversity needs to locate the most diverse sites. Species level is the most often considered taxonomic resolution. However, it is almost impossible to conduct a rapid species level survey of many hyperdiverse and difficult to identify taxa, mainly within arthropods, which are the main components of species richness. I tested whether higher taxa (genus and family) are good surrogates of species richness in three large and usually not surveyed groups in 16 reserves in Central-Hungary: Coleoptera (2415 spp), Diptera (1004 spp), and Acari (288 spp). Species richness of the reserves correlated strongly with both genus and family diversity for all groups. Species numbers also correlated between pairs of the three taxa, but not for genus and family numbers. Therefore, higher taxon diversity is a good surrogate of species diversity, but the diversity of one taxon can indicate the diversity of the other only at the species level.
