“…Maita‐Maita et al . () addressed the connectivity among populations of the leaf miner Angelabella tecomae (Gracillariidae) in the same region in the Atacama Desert using COI haplotypes and suggested that some gene flow had occurred among valleys in the desert. Similarly, our results indicated a weak population structure among populations of C. guacanivora , except for the Camiña population that presents a moderate level of differentiation (F ST ) compared to all other populations.…”

Although considered the driest desert in the world, the Atacama provides unique habitats and a reservoir of biodiversity for plants and insects. Caloptilia Hübner, 1825 (Gracillariinae), is a highly diverse genus of leaf miner micromoths that has not yet been recorded in Chile. In this study, we describe a new species of Caloptilia from a relict, vulnerable ecotone in the transverse valleys of the Atacama Desert in northern Chile. Adults, immature stages and natural history, including the mine of Caloptilia guacanivora Vargas-Ortiz & Vargas sp. nov., are described and illustrated. The larva is a leaf miner of the vulnerable, native, guacano tree Morella pavonis (Myricaceae). DNA barcode sequences were used to infer the specific status of C. guacanivora sp. nov. Results indicate that the new species is monophyletic with a genetic distance of around 5% to the nearest congener. We also used genetic variation to make preliminary inferences on the population structure and demography of this new taxon. This data revealed the presence of haplotypes shared among distant valleys, suggesting an ancient polymorphism that is widespread throughout populations in the region.

“…However, no clear differences were found in either case. The divergence between haplotypes of Angelabella from different spatial genetic clusters (3.6–8.3% K2P) is either remarkably higher than [ 5 ] or near [ 6 , 12 ] those recorded between morphologically cryptic species of two other genera of Gracillariidae. Similar levels of divergence have been interpreted to represent putative heterospecific lineages in the absence of morphological evidence [ 12 , 17 , 58 ].…”

“…A greater sampling effort is necessary to define lineage diversity at the metapopulation level for the type species and the three candidate species suggested here, which implies more detailed knowledge of their geographic ranges. Additional character sources must be assessed, including morphology of different life stages [ 64 , 65 ] and bi-parental markers [ 5 , 6 ], to understand better the processes and patterns that have governed the evolutionary history of this leaf miner genus.…”

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.
