Vespa matsumurai Sonan 1935 (= Vespa ducalis Smith 1852)
Type material. Sonan (1935b), having compared with Vespa ducalis var. pulchra, described this nominal taxon from Tokyo, Japan. He gave the same collection data “Ƥ, Tokyo, Oct. 13 1932 (Y. Nakamura)” for the holotype and the paratype. In TARI, there are the following three female specimens: 1 Ƥ labeled “Nishigahara / Tokyo / 13 X. 1932 / Y. Nakamura”, Type label, “ Vespa / matsumurai / Sonan / DET. J. SONAN ”, and “164”; 1 Ƥ labeled “Nishigahara / Tokyo / 13 X. 1932 / Y. Nakamura”, Paratype label, “ Vespa / matsumurai / Sonan / DET. J. SONAN ”, and “165”; and 1 Ƥ labeled “ISE / 1928 / J. YAMANOUCHI”, “ Vespa / matsumurai / Sonan / DET. J. SONAN ”, Paratype label, and “166”. As Sonan (1935b) did not mention the specimen from Ise, the specimen does not have any type status.
