What is "spondylidinae"

Spondylidinae are a small subfamily of Cerambycidae including slightly over 100 species, primarily in the coniferous forests of the Boreal hemisphere. A few species occur in coniferous forests in tropical and subtropical areas ( Mexico, Cuba), while very few genera (e.g., Zamium) are present in Austral Africa and Madagascar (e.g., Masatopus).
