Trochilus Chimborazo

DeLattre and Bourcier

Mount Chimborazo, Ecuador

.

Thought to be closely related to O. estella, O. stolzmanni and O. leucopleurus; all four have been considered conspecific; separated largely on morphological grounds. Race soderstromi sometimes thought to be an intergrade of jamesonii and nominate, but is apparently isolated geographically from both of them; nonetheless, it indicates clinality in the species, and reduces distinctiveness of jamesonii, with its lack of green throat patch (score reduced by soderstromi to 2) and less white in outer tail (1). Three subspecies recognized.
