Members of the genus Gnaphosa belong to the largest gnaphosid spiders. They are particularly interesting in nature conservation as their distribution is mainly restricted to disappearing natural non-forest habitats. In Europe, several Gnaphosa species groups occur. The exclusively Palaearctic group G. bicolor is characterised by a retrolaterally-shifted embolus, which occupies at least part of the middle one-third of the palpal bulb; females have laterally expanded epigyne and often have very elongated median epigynal ducts (Ovtsharenko et al. 1992). So far four species of this group have been identified in Europe, with a fifth species found in Central Asia (G. tarabaevi Ovtsharenko, Platnick Song, 1992). Two of the European species, G. bicolor (Hahn, 1831) and G. badia (L. Koch, 1866), are well known and their taxonomy and nomenclature is stable, but the same does not hold true for the other two.
隙蛛属的成员属于最大的暗蛛科蜘蛛。它们在自然保护方面特别有趣，因为它们的分布主要局限于正在消失的天然非森林栖息地。在欧洲，有几个隙蛛物种组。仅分布于古北区的双色隙蛛组的特征是栓塞向后侧移位，占据触肢器球部中间三分之一的至少一部分；雌性的外雌器侧向扩展，且通常有非常细长的中隔外雌器管（奥夫沙连科等人，1992年）。到目前为止，该组在欧洲已鉴定出4个物种，在中亚发现了第5个物种（塔拉别夫隙蛛，奥夫沙连科、普拉特尼克、宋，1992年）。欧洲的两个物种，双色隙蛛（哈恩，1831年）和暗色隙蛛（L. 科赫，1866年），是广为人知的，它们的分类和命名是稳定的，但其他两个物种并非如此。
