Parasitoid wasps of the genus play an important role in biological pest control, however, the genus includes a large number of cryptic species, which makes reliable identification difficult. The latest identification key dates back to Graham (1969) and since then many new species have been described and nomenclatural changes proposed.
Here we present an interactive and fully illustrated identification key in Xper3 for 27 species of the species group as well as for 18 similar species. In addition to qualitative traits, a large set of body measurements is incorporated in the key. We also explored a new set of qualitative features on the propodeum and metasternum. During field work, a new species of the species group, Baur sp. n., could be reared from flower heads of Asteraceae, which is described here. It looks very similar to and , however, several qualitative characters and body ratios distinguish it clearly from the most similar species.
属的寄生蜂在生物害虫防治中发挥着重要作用，然而，该属包含大量隐存种，这使得可靠鉴定变得困难。最新的鉴定检索表可追溯到格雷厄姆（1969年），从那时起，许多新物种被描述，命名也有变化。
在此，我们展示了一个在Xper3中针对该物种组的27个物种以及18个相似物种的交互式且有充分图解的鉴定检索表。除了定性特征外，该检索表还纳入了大量身体测量数据。我们还探索了前胸背板和后胸腹板上的一组新的定性特征。在野外工作期间，从菊科植物的花头中培育出了该物种组的一个新物种，即鲍尔新种，在此进行描述。它看起来与 和 非常相似，然而，几个定性特征和身体比例使其与最相似的物种明显区分开来。
