|Range||Isla Carrizal in the Caroní River, in northern Venezuela.|
It is 12 cm long. The males are gray with blue flecks, and the females are yellow.
The species has been described based on three specimens found in 2001; its only known habitat – stands of spiny guadua and ripidocladus spp. bamboo forest on the type locality – has been cleared to allow construction of the Tocoma Dam, but researchers are hopeful of finding the birds living elsewhere.
