Here, we present the descriptions of a new aphid species in the genus Pleotrichophorus Brner, 1930 (Hemiptera: Aphididae: Macrosiphini), found by Kenneth L. Hibbard, inspection supervisor for the Florida Department of Agriculture and Consumer Services, Division of Plant Industry. It is associated with Euthamia graminifolia (L.) Nutt. (Asteraceae) a native plant species in Florida, USA. Apterous and alate viviparous and oviparous females of Pleotrichophorus blackmani sp. n. are described and illustrated using light and scanning electron microscopy (SEM). SEM images of apterous viviparous female of Pleotrichophorus glandulosus (Kaltenbach, 1846), type species of the genus Pleotrichophorus, are given for the first time. Taxonomic notes are given, and an updated key to the apterae of the Euthamia-feeding aphids is provided. A multigene phylogenetic analyses of two New World Pleotrichophorus species places the genus in the tribe Macrosiphini sensu stricto. Pleotrichophorus glandulosus, the type species of the genus, was described from Germany. European specimens of P. glandulosus from France had similar molecular sequences to both Florida species, strongly suggesting that the new species belongs in Pleotrichophorus. COI and gnd sequence data indicate that P. blackmani sp. n. can be identified reliably by DNA barcodes.
在这里，我们描述了一种新的蚜属 Pleotrichophorus Brner，1930（半翅目：蚜科：Macrosiphini），由美国佛罗里达州农业和消费者服务部植物工业司的肯尼斯·L·希伯德（Kenneth L. Hibbard）发现。它与 Euthamia graminifolia（L.）Nutt.（菊科）有关，这是美国佛罗里达州的一种本地植物。本文描述并通过光学显微镜和扫描电子显微镜（SEM）对 Pleotrichophorus blackmani sp. n. 的无翅和有翅胎生和卵生雌性进行了描述和说明。首次给出了 Pleotrichophorus glandulosus（Kaltenbach，1846），即该属的模式种的无翅胎生雌性的 SEM 图像。给出了分类学注释，并提供了一个更新的以 Euthamia 为食的蚜虫无翅蚜的关键。对两个新世界 Pleotrichophorus 物种的多基因系统发育分析将该属置于 Macrosiphini 族中。该属的模式种 Pleotrichophorus glandulosus 来自德国。来自法国的 Pleotrichophorus glandulosus 的欧洲标本与佛罗里达的两个物种具有相似的分子序列，这强烈表明新物种属于 Pleotrichophorus。COI 和 gnd 序列数据表明，P. blackmani sp. n. 可以通过 DNA 条形码可靠地识别。
