Heliozela pitangavora Moreira & Fochezato sp. nov. (Lepidoptera: Adeloidea: Heliozelidae), a leaf miner of Eugenia uniflora L. (Myrtaceae) is described in southern Brazil. Larvae, pupae and adults are characterized using optical and scanning electron microscopy, in association with data on their life history. Mitochondrial DNA (COI) sequences are provided and compared with closely related species. Individual mines initially appear as small blotches on the adaxial surface of leaves during the summer, progressively enlarging as larvae feed on leaf parenchyma. Mature larvae build typical dehiscent shields by cutting the leaf lamina, and moulting into the final, highly modified, non-feeding instar. Pupation occurs later within these shields, in the soil litter, during autumn-winter. This is the first report for Heliozela Herrich-Säffer in Brazil, and the first record of such a host-plant species for the family worldwide.
巴西南部描述了一种新物种——番石榴潜叶蛾（Heliozela pitangavora Moreira & Fochezato sp. nov.，鳞翅目：巢蛾总科：潜蛾科），它是番石榴（Eugenia uniflora L.，桃金娘科）的潜叶虫。利用光学显微镜和扫描电子显微镜，结合其生活史数据，对幼虫、蛹和成虫进行了特征描述。提供了线粒体DNA（COI）序列，并与近缘物种进行了比较。夏季时，单个虫道最初在叶片正面呈现为小斑点，随着幼虫取食叶肉组织，斑点逐渐扩大。成熟幼虫通过切割叶片形成典型的开裂盾牌，并蜕皮进入最后一个高度特化的不取食龄期。秋冬季节，蛹在这些盾牌内、土壤落叶层中化蛹。这是潜蛾属（Heliozela Herrich-Säffer）在巴西的首次报道，也是该科在全球范围内首次记录到以这种寄主植物为食的物种。
