P. L. Sclater and Salvin, 1873,
high Ecuador between Riobamba and Mocha.
Sometimes placed in genus Nettion. Usually treated as conspecific with A. flavirostris, but separation as full species accepted here on basis of coloration and published morphometric distinctions#R, namely all-dark vs half-yellow bill (3); longer bill, which is not simply correlated with slightly larger size of bird (andium 39–42, altipetens 40–42 vs flavirostris 29–38, oxyptera 33–37; allow 2); lack of tawny-buff tinge in head and upperbody plumage (1); longer wing (mean male altipetens 225, andium 233 vs flavirostris 197, median oxyptera 215; allow 1). A. andium differs also from adjacent High Andean race oxyptera of A. flavirostris on account of same first three characters above (6), plus heavily vs lightly dark-mottled breast, mantle and back and dingy grey-brown vs greyish-cream underparts (2). Two subspecies recognized.
