So far, six species of Oxeoschistus Butler, including its junior synonym Dioriste Thieme, were listed from Central America, with five of them from Costa Rica alone, which appears to represent the highest regional diversity of this Neotropical montane butterfly genus. Our research based on field work, morphological studies and barcode analysis proved that one record is a misunderstanding perpetuated in scientific literature for over a century: Oxeoschistus cothonides Grose-Smith is identified here as an individual form of the female of O. cothon Salvin. The presence of Oxeoschistus tauropolis (Westwood) in Costa Rica, subject to some controversy, is confirmed, and a new local subspecies is described from Costa Rica, O. tauropolis mitsuko Pyrcz & Nakamura n. ssp. Specific status of O. euriphyle Butler is reinstated based on morphological and molecular data. A new subspecies O. hilara lempira Pyrcz n. ssp. is described from Honduras. O. puerta submaculatus Butler is reported for the first time from the Darién region on the Panama–Colombia border. Species relationships are preliminarily evaluated based on COI data concluding, among others, that O. hilara and O. euriphyle are less closely related than previously assumed. Altitudinal and distributional data are revised, and ecological and behavioural information of all the species of Central American Oxeoschistus is provided.

关于中美洲云雾森林蝴蝶属Oxeoschistus Butler的修订说明（鳞翅目：Nymphalidae：Satyrinae）。

到目前为止，从中美洲列出了6种Oxeoschistus Butler，包括其低级同义词Dioriste Thieme，其中仅从哥斯达黎加就有5种，这似乎代表了这一新热带山地蝴蝶属的最高区域多样性。我们基于野外工作，形态学研究和条形码分析的研究证明，一个记录在一个多世纪以来一直是科学文献中的一种误解：Oxeoschistus cothonides Grose-Smith在这里被认为是O. cothon Salvin雌性的一种个体形式。Oxeoschistus tauropolis的存在哥斯达黎加（韦斯特伍德）（韦斯特伍德（Westwood））的确受到争议，并从哥斯达黎加（O. tauropolis mitsuko Pyrcz和Nakamura n。）描述了一个新的当地亚种。ssp。根据形态学和分子数据，恢复了稻曲霉巴特勒的特殊状态。一个新的亚种O. hilara lempira Pyrcz n。ssp。由洪都拉斯描述。巴拿马-哥伦比亚边界的达里恩地区首次报道了O. puerta submaculatus Butler。根据COI数据初步评估了物种之间的关系，这些数据包括O. hilara和O. euriphyle等与以前假设的关系不那么紧密。修改了海拔和分布数据，并提供了中美洲Oxeoschistus所有物种的生态和行为信息。
