Two Species Delimitation of (Hemiptera: Diaspididae) Based on Morphology, Molecular Clustering, and Niche Differentiation.

and are notorious pests and commonly feed on various ornamental plants and fruit trees worldwide. The two species share many host-plant species, and are similar in morphological characteristics and life cycle, making it difficult to distinguish to distinguish between them. In this study, morphological characteristics, molecular evidence, and ecological niches were used to define these species.
