Background Iridopsis Warren, 1894 (Lepidoptera: Geometridae: Ennominae: Boarmiini) is a New World moth genus mainly diversified in the Neotropical Region. It is represented in Chile by two described species, both from the Atacama Desert. New information Iridopsis socoromaensis sp. n. (Lepidoptera: Geometridae: Ennominae: Boarmiini) is described and illustrated from the western slopes of the Andes of northern Chile. Its larvae were found feeding on leaves of the Chilean endemic shrub Dalea pennellii (J.F. Macbr.) J.F. Macbr. var. chilensis Barneby (Fabaceae). Morphological differences of I. socoromaensis sp. n. with the two species of the genus previously known from Chile are discussed. A DNA barcode fragment of I. socoromaensis sp. n. showed 93.7-94.3% similarity with the Nearctic I. sanctissima (Barnes & McDunnough, 1917). However, the morphology of the genitalia suggests that these two species are distantly related. The discovery of I. socoromaensis sp. n. highlights the need for additional surveys in underexplored areas to understand better the taxonomic diversity and evolutionary relationships of the mainly Neotropical moth genus Iridopsis.

Iridopsis socoromaensis sp. n.，一种来自智利北部安第斯山脉的几何蛾（鳞翅目，几何蛾科）

背景 Iridopsis Warren，1894 年（鳞翅目：Geometridae：Ennominae：Boarmiini）是一种新世界蛾属，主要分布在新热带地区。它在智利以两种被描述的物种为代表，均来自阿塔卡马沙漠。新信息 Iridopsis socoromaensis sp. n. （鳞翅目：Geometridae：Ennominae：Boarmiini）是从智利北部安第斯山脉的西坡描述和说明的。发现其幼虫以智利特有灌木 Dalea pennellii (JF Macbr.) JF Macbr 的叶子为食。变种。chilensis Barneby（豆科）。I. socoromaensis sp的形态差异。n. 讨论了以前从智利已知的两个属的物种。I. socoromaensis sp. 的 DNA 条形码片段。n. 与 Nearctic I. sanctissima 的相似性为 93.7-94.3%（Barnes & McDunnough，1917）。然而，生殖器的形态表明这两个物种是远亲。I. socoromaensis sp. 的发现 n. 强调需要在未充分开发的地区进行额外调查，以更好地了解主要是新热带蛾属虹膜属的分类多样性和进化关系。
