Studies conducted in river Ererê located in the left margin of Negro River, municipality of Barcelos, state of Amazonas, have confirmed that has as its natural habitat the palm tree . By scanning electron microscopy, sensillum type was studied on the antennae of . The specimens used come from the field and laboratory colony. No differences were observed between and other Triatominae studied. In the antennas, differences were observed only between the antennal segments and in the dorsal and ventral portions. Trichobothria sensilla show a difference with a lamellar base, suggesting that this conformation of the base of the sensilla is a synapomorphic feature of the genus. Another important observation is that, considering that is a specialist, infesting only one type of palm tree, trichoidea sensilla may be involved with plant-derived odorants. The knowledge of such functions could benefit the understanding of the likely biological role of these structures in chemical communication and also provide basic information for future studies of niche recognition, since this species of triatomine is only found in the palm.
在位于亚马孙州巴塞洛斯市黑河左岸的埃雷雷河进行的研究证实，[物种名称]的自然栖息地是[棕榈树名称]。通过扫描电子显微镜，对[物种名称]触角上的感器类型进行了研究。所使用的标本来自野外和实验室种群。在[物种名称]与其他研究过的锥蝽亚科之间未观察到差异。在[物种名称]的触角中，仅在触角节以及背侧和腹侧部分观察到差异。毛形感器显示出具有片状基部的差异，这表明感器基部的这种构象是该属的一个共衍征特征。另一个重要观察结果是，考虑到[物种名称]是一种专性物种，仅侵染一种棕榈树，毛形感器可能与植物源气味剂有关。了解这些功能有助于理解这些结构在化学通讯中可能的生物学作用，也为未来生态位识别研究提供基础信息，因为这种锥蝽仅在[棕榈树名称]棕榈中发现。
