We report an unknown taxon of bot fly (Diptera: Oestridae: Oestrinae) in red river hogs ( Linnaeus, 1758) in Cross River State, Nigeria. From direct observation and interviews with local hunters, we document that, remarkably, the parasite typically occurs within the intracranial supra-meningeal space - i.e., between the inner wall of the skull and the brain - but without causing visible inflammation or clinical signs. The parasite is most similar (up to 87.9%) to based on cytochrome oxidase subunit 1 DNA sequencing but is sufficiently divergent phylogenetically to represent a new or previously un-sequenced taxon. Morphologically, the parasite shares some, but not all, features with . Local cultural belief systems attribute aspects of red river hog behavior (e.g. intelligence, elusiveness) to the parasite, suggesting a prolonged presence in the red river hog population. The parasite's unusual anatomic location may be aberrant, or it may be a protective adaptation to life in red river hogs, which forage vigorously with their snouts.
我们报告了在尼日利亚克罗斯河州的红河野猪（Linnaeus，1758）体内发现的一种未知种类的肤蝇（双翅目：狂蝇科：狂蝇亚科）。通过直接观察以及与当地猎人的访谈，我们记录到，值得注意的是，这种寄生虫通常存在于颅内脑膜上间隙——即颅骨内壁与大脑之间——但不会引起明显的炎症或临床症状。基于细胞色素氧化酶亚基1的DNA测序，该寄生虫与[某物种]最为相似（相似度高达87.9%），但在系统发育上差异足够大，代表一个新的或之前未测序的分类单元。在形态上，该寄生虫与[某物种]有一些但并非全部共同特征。当地的文化信仰体系将红河野猪的一些行为特征（如聪明、难以捉摸）归因于这种寄生虫，这表明它在红河野猪种群中存在已久。这种寄生虫不寻常的解剖位置可能是异常现象，也可能是对以鼻子大力觅食的红河野猪生活的一种保护性适应。
