Etymology: Biotodoma: Greek, biotos, ou = life, existence + Greek, domos = house (Ref. 45335).
Eponymy: The etymology is not explained, but perhaps named for Cupid, the Roman god of love and desire; or generically meaning ‘desire’ or ‘longing’, perhaps alluding to the desirable nature of its attractive appearance in life. (Ref. 128868), visit book page.
