Although diverse and widespread, there is much to improve on the knowledge of Zethus Fabricius, 1804 wasps. This includes aspects of many areas, such as data on taxonomy, behavior and biology. In the present study, we investigated Zethus plaumanni Bohart Stange, 1965, a species hitherto known only from the female type in the literature, and worked to fill gaps on the knowledge of this species by describing the male and its genitalia, the nest structure and giving notes on the biology of individuals collected in trap-nests in southern Brazil. The male is diagnosable by characters also used for female identification. The nest follows the pattern of typical pre-existing cavity users, with a remarkable multi-layered nest plug. Sex ratio follows the 1:1 rule and sampling indicates diapause in the adult phase.
尽管泽图斯·法布里丘斯（Zethus Fabricius） 1804 年黄蜂种类繁多且分布广泛，但仍有许多方面需要改进。这包括分类学、行为和生物学等多个领域的数据。在本研究中，我们调查了泽图斯·普拉曼尼·博哈特·斯坦格（Zethus plaumanni Bohart Stange, 1965），这是一种迄今为止仅在文献中雌性模式种中被描述的物种，我们努力通过描述雄性及其生殖器、巢穴结构，并记录在巴西南部陷阱巢中收集的个体的生物学信息来填补对该物种的认识空白。雄性可以通过也用于雌性鉴定的特征来识别。巢穴遵循典型的预先存在的洞穴使用者模式，具有显著的多层巢穴塞。性别比例遵循 1:1 的规则，且样本表明成虫期存在滞育。
