Spondylidinae (often misspelled "Spondylinae") 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).
Spondylidinae are insects characterised by cerambycine aspect, generally with a more or less flattened, dark body, oblique head and scarcely elongated antennae.
A later study of the wing morphology[4] confirmed Xambeu's grouping, but by the end of the 20th Century (and in some contemporaneous faunas) Spondylidini were treated as a separate subfamily.
Spondylidini - whose larvae are indistinguishable from that of all other traditional Aseminae - appear to be simply highly derived Asemini, with adult morphology convergent with lucaniform Prioninae and the Vesperidae of the Amazon rainforest genus Migdolus.
