Tang, F.T., Wu, S.A., & Li, H.P. 1997 [A discussion on the type species of the genus Matsucoccus with Sonsaucoccus as its new synonym (Homoptera: Margarodidae).]. Entomotaxonomia 19: 17-23.

Notes: Revision of the genus Matsucoccus. Due to the imperfect original description, types preserved and redescribed by Herbert (1921) and Morrison (1928) in USA were excessively trusted. Moreover, the Japanese fauna of the genus is considered to be simple and represented only by this species, but a recent study expresses that there are 2 species even in original description of Kuwana in Japan: one with larger size and damaging to black pine; the other with smaller size and damaging to red pine. They may be named the black pine bast scale and the red pine bast scale separately. After a study and revision on related literatures, we found that black pine bast scale is the real M. matsumurae (= M. thunbergianae Miller et Park, 1987) fitting the description of the holotype; the red pine bast scale is the so-called 'M. matsumurae' in the past, which may be the species liaoningensis Tang (1978) or resinosae Bean et Godwin (1955). The genus Sonsaucoccus Young (1980) is treated as a junior synonym of the genus Matsucoccus. Key to the Palaearctic species of the genus is made.
