摘要对新热带低地森林蝴蝶区系中最常见的成员之一Colobura Billberg属（1820）的分类学进行了综述，根据现有的未成熟期和成虫的形态学资料对其分类进行了评述。尽管迄今为止几乎所有的作者都认为Colobura是单型的，但Colobura包含两个物种，其中一个在这里被描述为Colobura annulata sp. n.。新物种和Colobura dirce （Linnaeus, 1758）的未成熟阶段都被描述、比较和计算。两种昆虫的幼虫和成虫表型可以很容易地分离，并提供了鉴定的关键。对两种植物的未成熟阶段、寄主植物和成虫行为的已发表和未发表的信息进行了回顾，揭示了生态位划分的可能情况；小蠹蛾幼虫在幼树或幼树上单生或成群，而环蠹蛾幼虫在成熟树冠上高度群居。有证据表明，成虫的飞行高度可能在一定程度上与首选寄主植物的高度有关。
Abstract The taxonomy of the genus Colobura Billberg, 1820, one of the most common members of the Neotropical lowland forest butterfly fauna, is critically reviewed in light of available information on the morphology of both the immature stages and adults. Although regarded by almost all authors to date as monotypic, Colobura contains two species, one of which is described here as Colobura annulata sp. n. The immature stages of both the new species and Colobura dirce (Linnaeus, 1758) are described, compared, and figured. Both larval and adult phenotypes of the two species may be readily separated, and a key to identification is provided. A review of published and unpublished information on the immature stages, hostplants, and adult behavior of both species reveals a possible case of ecological niche partitioning; larvae of C. dirce are solitary or occur in small groups on predominantly young trees or saplings, whereas those of C. annulata are highly gregarious on mature canopy trees. There is some evidence to suggest that adult flight height may, in part, be correlated with the height of preferred hostplants.
