French: Métallure verte German: Grünes Glanzschwänzchen Spanish: Metalura Verde
Other common names: Colombian Metaltail (recisa); Ecuadorian Metaltail (primolinus); Black-throated Metaltail (atrigularis)

Taxonomy: Trochilus Williami DeLattre and Bourcier, 1846, vicinity of Popayán, Colombia.
Forms superspecies with M. aeneocauda, M. eupogon, M. theresiae, M. odomae and M. baroni; recently recorded as occurring sympatrically with M. odomae in Podocarpus National Park (S Ecuador), indicating that this part of superspecies may not hold good; also recently found to be sympatric with M. baroni at R Mazan in Azuay (S Ecuador), though altitudinally segregated, occurring at lower elevations. Some authors have considered the races to constitute four distinct species. Races primolinus and atrigularis form a zone of intergradati.. View all taxonomy...

Taxonomy: Trochilus Williami DeLattre and Bourcier, 1846, vicinity of Popayán, Colombia.
Forms superspecies with M. aeneocauda, M. eupogon, M. theresiae, M. odomae and M. baroni; recently recorded as occurring sympatrically with M. odomae in Podocarpus National Park (S Ecuador), indicating that this part of superspecies may not hold good; also recently found to be sympatric with M. baroni at R Mazan in Azuay (S Ecuador), though altitudinally segregated, occurring at lower elevations. Some authors have considered the races to constitute four distinct species. Races primolinus and atrigularis form a zone of intergradation in C Ecuador (Chimborazo). Race primolinus sometimes misspelt as primolina, but is masculine noun based on name of Prince Primoli, grandson of C. L. Bonaparte. Four subspecies currently recognized.
