The new plant bug Engytatus passionarius sp. nov. from Formosa province in northern Argentina is described. This new dicyphine was always found in association with the sticky herbaceous vine Passiflora (Dysosmia) foetida L. (Passifloraceae), a species native to the Americas and an important invasive weed in some countries including Australia. The apparent host specificity, the ability to traverse the adhesive exudates of the glandular trichomes and the damage caused by nymphal and adult feeding make E. passionarius sp. nov. an interesting option for further research as a biological control agent. In this paper, a diagnosis, description and illustrations of adult, including the male genitalia, of this new species, as well as a key to the Argentinian species of Engytatus are provided.

西番莲属。十一月 (半翅目: Miridae), 侵入性臭西番莲 Passiflora foetida L 的新天敌。

新植物臭虫Engytatus Passionarius sp。十一月 来自阿根廷北部福尔摩沙省的描述。这种新的双环孢素总是与粘性草本藤本西番莲 (Dysosmia) foetida L. (Passifloraceae)一起被发现，后者是一种原产于美洲的物种，在包括澳大利亚在内的一些国家是一种重要的入侵杂草。表观宿主特异性，遍历腺毛的粘合剂渗出物的能力，并且所造成的若虫和成虫馈送化妆损坏E. passionarius 藻。十一月作为生物防治剂的进一步研究的一个有趣的选择。在本文中，提供了这个新物种的成体（包括雄性生殖器）的诊断、描述和插图，以及阿根廷物种Engytatus的关键。
