Scolytoplatypus raja Blandford

Scolytoplatypus raja Blandford, 1893: 440 .

Recorded from Bhutan by Schedl (1975 as Scolytoplatypus mikado Blandford). Schedl made frequent errors in identifying and synonymising species of Scolytoplatypus (Beaver & Gebhardt 2006) . The species, S. mikado, has a more northerly distribution than S. raja, and records of the former species from Bhutan, India and Southeast Asia almost certainly all refer to S. raja (Beaver & Gebhardt 2006) .

Distribution. Bhutan, China (Xizang, Yunnan), India (Assam, Himachal Pradesh, Uttar Pradesh, West Bengal), Laos, Kashmir, Nepal, Pakistan, Taiwan, Thailand, Vietnam, West Malaysia.

Biology. The biology and life history of Scolytoplatypus species are described by Beeson (1961), Browne (1961 a), Beaver & Gebhardt (2006) and Beaver & Liu (2018). Scolytoplatypus raja is a polyphagous species attacking both coniferous and angiosperm trees (Beeson 1961, Maiti & Saha 2009, Wood & Bright 1992).
