The nectarivorous lories and lorikeets ( Loriini ) are a diverse group that radiated across Indonesia, the Philippines, Australia, and the South Pacific, having their highest diversity on New Guinea. The clade exhibits a wide range of within Loriini occurred at 14.2 Mya (6.0–19.5) body sizes and plumage colors (Merwin et al., and 12.5 Mya (4.8–17.5; fig. 14). Within clade 2, 2020).
