Abstract

During a recent survey of leaf-mining microlepidoptera in the Cerrado biome, mines of an undescribed Porphyrosela Braun (Lepidoptera: Gracillariidae: Lithocolletinae) were found associated with the forage peanut, Arachis pintoi Krapov. W.C. Greg. (Fabaceae). Consequently, adults, immature stages and the leaf mine of Porphyrosela arachisella sp. nov. are herein described based on light and scanning electron microscopy. A preliminary analysis of DNA barcode sequences including putative members of other lithocolletine species and all BINs (Barcode Index Numbers) available for Porphyrosela supports P. arachisella as an independent cluster, with 8 to 11% divergence. Its nearest neighbour was the cluster formed by three BINs (BOLD: ADT2137, BOLD: AAG1161 and BOLD: ADU9985) that includes specimens from Australia, Vietnam and Bangladesh. This is the first report of a lithocolletine gracillariid for Brazil, and the third species recognized for the genus in the Neotropical region.

摘要

在最近对塞拉多生物群中的潜叶蝇科微蛾进行的调查中，发现了一种未被描述的 Porphyrosela Braun（鳞翅目：Gracillariidae：Lithocolletinae）与饲料花生 Arachis pintoi Krapov. W.C. Greg.（豆科）有关。因此，本文基于光学显微镜和扫描电子显微镜描述了 Porphyrosela arachisella sp. nov. 的成虫、幼虫和叶片虫瘿。对包括其他 lithocolletine 物种的假定成员和所有 Porphyrosela 可用的 BIN（条形码索引编号）的 DNA 条形码序列的初步分析支持 P. arachisella 作为一个独立的聚类，具有 8 到 11%的差异。它最近的邻居是由三个 BIN（BOLD：ADT2137、BOLD：AAG1161 和 BOLD：ADU9985）组成的聚类，其中包括来自澳大利亚、越南和孟加拉国的标本。这是巴西首次报道的 lithocolletine gracillariid，也是新热带地区第三个性识别的属。
