    Americas: Costa Rica, Panama

    Neotropical

Distribution Notes:

Costa Rica (uplands of Cordillera Central).

Notes:

Wilson (2003) provisionally synonymized innupta Menozzi under alfaroi. So far, a pattern has held that leads us to treat them as two distinct species. alfaroi is dirty yellow and nests in dead wood on the ground. innupta is always black and nests under epiphytes, usually in the canopy. innupta and alfaroi are sympatric in the Vara Blanca area of Braulio Carrillo National Park.

diana Forel, with which alfaroi may be confused, is yellow, but lacks transverse striae on the vertex.
