Abstract:
[Objectives] To provide a guide to the morphological identification of Pseudococcus nakaharai Gimpel & Miller, a species not previously reported in China. [Methods] Slide-mounted specimens, morphological analysis, micrometer measurements and dichasial taxonomy retrieval were used to find morphological criteria that can reliably identify P. nakaharai. [Results] A detailed description and structural measurements of adult female P. nakaharai, congeners, hosts, and the species’ distribution, are provided, as well as a key to adult females of P. nakaharai and similar species. [Conclusion] The information presented in this paper following the first detection of P. nakaharai in China should improve the future quarantine and identification of this pest.
