Moustached Flowerpiercer (Diglossa mystacalis)


French: Percefleur moustachu German: Barthakenschnabel Spanish: Pinchaflor bigotudo

Diglossa mystacalis


, 1846,

yungas of La Paz, Bolivia


Closely related to and formerly considered conspecific with D. gloriosissima and D. lafresnayii; molecular data indicate that D. gloriosissima and present species are more closely related to each other than either is to D. lafresnayii. Races moderately distinctive and variation appears not to be clinal, hence here treated as groups; further study perhaps warranted. Four subspecies recognized.
