Abstract: 【Aim】 The scientific name of black glue whitefly is Aleuroplatus pectiniferus Quaintance & Baker. In some previous reports, Aleurotrachelus camelliae (Kuwana) was misidentified as black glue whitefly. In this study, we distinguished A. pectiniferus and A. camelliae by comparing their morphological differentiation. 【Methods】 We redescribed these two species of whiteflies collected by mounting the slide specimens and observation under scanning electron microscope (SEM). 【Results】 The morphological characteristics of puparium were redescribed， and the data of host plants and distribution and the live images and slide and SEM photographs of puparia of these two whitefly species were provided. A. pectiniferus resembles A. camelliae in the presence of the white wax secretions at the end of thoracic and caudal tracheal folds, but differs from the latter in the smaller size of puparium, the presence of the comb structure composing of 3-4 teeth at the end of thoracic and caudal tracheal folds， and the presence of the submedian depressions on each abdominal segment. 【Conclusion】 We unified and proposed the Chinese common name for A. pectiniferus and A. camelliae, respectively.
