Among the Nearctic species of Phenacoccus (Hemiptera: Pseudococcidae), Phenacoccus solani Ferris and P. defectus Ferris are morphologically similar and it can be difficult to separate them on the basis of microscopic morphological characters of the adult female alone. In order to resolve their identity, a canonical variates morphological analysis of 199 specimens from different geographical origins and host plants and a molecular analysis of the COI and 28S genes were performed. The morphological analysis supported synonymy of the two species, as although the type specimens of the "species" are widely separated from each other in the canonical variates plot, they are all part of a continuous range of variation. The molecular analysis showed that P. solani and P. defectus are grouped in the same clade. On the basis of the morphological and molecular analyses, P. defectus is synonymized under the senior name P. solani, syn. n.
在新北区的粉蚧属（半翅目：粉蚧科）物种中，茄粉蚧费里斯氏菌和缺陷粉蚧费里斯氏菌在形态上相似，仅根据成年雌性的微观形态特征很难将它们区分开来。为了确定它们的身份，对来自不同地理来源和寄主植物的199个标本进行了典型变量形态分析，并对COI和28S基因进行了分子分析。形态分析支持这两个物种为同物异名，因为尽管“物种”的模式标本在典型变量图中彼此相距甚远，但它们都是连续变异范围的一部分。分子分析表明，茄粉蚧和缺陷粉蚧归为同一进化枝。基于形态和分子分析，缺陷粉蚧被归为高级名称茄粉蚧的同物异名，新异名。
