Angelabella (Lepidoptera: Gracillariidae: Oecophyllembiinae) is considered a monotypic Neotropical genus of leaf miner micromoths known only from a few valleys of the arid environments of the Peru-Chile desert, particularly the southernmost part of Peru and northernmost part of Chile (type locality), where natural populations of its primary host plant occur. The geographic distribution of potential host plants provides a scenario for a wider range for this micromoth genus. The aims of this study were to explore the geographic range of Angelabella, determine the spatial distribution of mitochondrial lineages, and test lineage conspecificity hypotheses. The spatial distribution of genetic diversity indicated the presence of four spatial clusters, three of which are north of the previously known geographic range. Genetic distances were 0.2–0.8% and 3.6–8.3% (K2P) between haplotypes of the same and different spatial clusters, respectively. Phylogenetic relationships indicated reciprocal monophyly among the four spatial clusters, suggesting that allopatric differentiation processes have governed the recent history of Angelabella in these arid environments. These groups were defined as different species by four species delimitation methods, suggesting that Angelabella is not a monotypic genus, but harbors at least four morphologically cryptic allopatric species with restricted geographic ranges, including the type species and three candidate species.

秘鲁智利沙漠中单性新热带微蛾属安格拉贝拉属（鳞翅目：Gra科）的隐性多样性

Angelabella（鳞翅目：Gracillariidae：Oecophyllembiinae）被认为是单叶类蛾的新近性属，仅从秘鲁-智利沙漠的干旱环境中的几个山谷知道，特别是秘鲁的最南部和智利的最北部（类型局部性） ，这里是其主要寄主植物的自然种群。潜在寄主植物的地理分布为该蛾类的广泛应用提供了一种可能性。这项研究的目的是探索Angelabella的地理范围，确定线粒体谱系的空间分布，并检验谱系同构性假设。遗传多样性的空间分布表明存在四个空间簇，其中三个在先前已知的地理范围以北。同一和不同空间簇的单倍型之间的遗传距离分别为0.2–0.8％和3.6–8.3％（K2P）。系统发生关系表明这四个空间簇之间具有相互的单亲关系，这表明在这些干旱环境中，异相分化过程主导了安格拉贝拉的近代史。通过四种物种划界方法将这些群体定义为不同物种，这表明安杰拉贝拉 它不是单型属，而是包含至少四个地理范围受限的形态隐密的异特异物种，包括类型物种和三个候选物种。
