Booth, J.M., & Gullan, P.J. 2006 Synonymy of three pestiferous Matsucoccus scale insects (Hemiptera: Coccoidea: Matsucoccidae) based on morphological and molecular evidence.. Proceedings of the Entomological Society of Washington 108(4): 749-760.
Notes: The scale insect genus Matsucoccus Cockerell (Coccoidea: Matsucoccidae) contains several economically important species that cause damage to pine trees, Pinus species, in the United States and elsewhere in the Holarctic Region. Efforts to reconstruct the phylogeny of the group have provided information on synonymy based on newly acquired molecular data and reassessment of morphological data. Matsucoccus resinosae Bean and Godwin, described from the eastern United States, and Matsucoccus thumbergianae Miller and Park, from South Korea, are considered to be new synonyms of Xylococcus (now Matsucoccus) matsumurae Kuwana. The taxonomic confusion surrounding these names is discussed. In addition, we suggest that several other species of Matsucoccus, including M. pini Green, should be investigated as possible synonyms of M. matsumurae.
