Bark and Ambrosia Beetles of the World

Bright (1969) treated maculosus Blackman as a synonym of variegatus Blandford. The two ‘species’ as treated by Wood (1982) are narrowly parapatric. Further collecting in northern Mexico may close the distribution gap.

Records of this species prior to 1969 may refer to P. pini Wood which was described that year. Bright (1970) designation a specimen in the Museum of Comparative Zoology as a lectotype. Wood & Bright (1992) make no mention of this and refer to a holotype in Helsinki.

Wood (1969) described this species after the publication of Bright’s (1969) treatment of the genus Pseudohylesinus. Some of the collections attributed to P. sericeus probably refer to this species.

Bright (1969) treated this as a synonym of variegatus Blandford.
