Background Astrotischeria Puplesis & Diškus, 2003 (Lepidoptera, Tischeriidae) is a New World genus of micromoths whose larvae are leaf miners associated mainly with plants of the family Asteraceae. The original description of the type species Astrotischeria karsholti Puplesis & Diškus, 2003 was based on adults from central Peru. No additional distribution records, host plants or DNA barcodes have been documented for this species. New information Astrotischeria karsholti is reported for the first time from Chile, based on adults obtained from leaf mines of Ambrosia cumanensis Kunth (Asteraceae) collected in the transverse valleys of the Atacama Desert. This discovery expands the distribution range of this micromoth nearly 900 km to the southeast and represents its first host plant record. Divergence between DNA barcodes of A. karsholti and the nearest congeneric was 6% (K2P). A Maximum Likelihood analysis, based on DNA barcodes, raises questions about the monophyly of Astrotischeria.

新热带小蛾 Astrotischeria karsholti Puplesis 的新分布记录、第一个寄主植物记录和 DNA 条形码Diškus（鳞翅目，Tischeriidae）

背景 紫星天蛾Diškus, 2003（鳞翅目，Tischeriidae）是新世界小蛾属，其幼虫是主要与菊科植物相关的潜叶蛾。模式种 Astrotischeria karsholti Puplesis & 的原始描述Diškus，2003 年以秘鲁中部的成年人为基础。尚未记录该物种的其他分布记录、寄主植物或 DNA 条形码。新的信息 智利首次报道了 Astrotischeria karsholti，其成虫是从阿塔卡马沙漠横谷采集的 Ambrosia cumanensis Kunth（菊科）叶矿中获得的。这一发现将这种小蛾的分布范围扩大到东南近900公里，代表了其第一个寄主植物记录。 A. karsholti 和最接近的同类 DNA 条形码之间的差异为 6% (K2P)。基于 DNA 条形码的最大似然分析提出了关于 Astrotischeria 单一系的问题。
