What is "phrygilus"

Phrygilus is a genus of mainly Andean seed-eating tanagers commonly known as sierra finches. Phrygilos means finch in Ancient Greek. Sometimes classified in the bunting and American sparrow family Emberizidae, more recent studies have shown them to belong in the Thraupidae. The genus appears to be polyphyletic consisting of at least three distinct lineages which in future may need to be split into separate genera.
