Buprestis subornata
(LeConte, 1860)
Buprestis subornata is a metallic wood-boring beetle in the Buprestidae, native to North America. The was described by LeConte in 1860 and belongs to the subgenus Buprestis s. str. It has been recorded from western North America including British Columbia, with specimens documented from locations such as Kelowna. The species has been involved in taxonomic confusion, with specimens historically misidentified as the Palearctic species Buprestis haemorrhoidalis. Two are recognized: B. subornata subornata and B. subornata punctiventris Casey.

Identification
Distinguished from the superficially similar Palearctic Buprestis haemorrhoidalis by having poorly-defined, impunctate elytral intervals (versus well-defined, serially punctate intervals in B. haemorrhoidalis) and a less smooth, less shiny elytral surface. The two species belong to different subgenera: B. subornata in Buprestis s. str. and B. haemorrhoidalis in Ancylocheira. B. subornata punctiventris differs from the nominate subspecies in punctation of the surface.
Distribution
Native to North America. Documented from western localities including British Columbia, Canada (specifically Kelowna). Distribution extends through western regions of the continent.
Human Relevance
Has been subject to taxonomic misidentification with significant implications for documentation. A specimen misidentified as the B. haemorrhoidalis was erroneously reported as established in Canada, highlighting the importance of authoritative identification and voucher specimen verification when documenting occurrences. Correct identification by buprestid has rectified this record.

Misconceptions
Specimens of this native North American were long misidentified as the Palearctic species Buprestis haemorrhoidalis, leading to erroneous reports of an established in Canada. This misidentification persisted in literature and databases for years before correction by buprestid taxonomic .
