Trochilus (——?) castaneoventris
Cordillera de Chiriquí, 6000 feet [c. 1830 m], Panama.
Classification unstable; commonly treated as conspecific with L. calolaemus and L. cinereicauda, but, while females of all taxa are very similar, combination of highly distinctive male plumages and parapatric distributions, along with observations that where white-throated and purple-throated forms occur on the same slopes they tend to segregate altitudinally (white-throated higher), suggests species status more appropriate; hybridization is very limited, and many previous reports of hybrids may refer to young birds. Thus, castaneoventris achieves species status, distinct from calolaemus by its white vs purple throat (3), green vs blue forecrown (3) and parapatry (3), and from cinereicauda by its green vs blue forecrown (3), dark blue vs grey tail (3) and parapatry (3). Monotypic.
Extreme W Panama (mountains in W Chiriquí).
