Bolborrhynchus [sic] Luchsi
Usually regarded as conspecific with M. monachus, but treated as separate species in HBW (and this is supported by recent genetic analysis#R) on basis of characters now scored as follows: uniform (unbarred) and much paler grey breast and crown (also no bars on mantle) (3); pure buffy-mustard vs yellow-tinged grey mid-belly (2); stronger green in all areas (1); bluer tail and darker flight-feathers and wing-coverts (ns); darkish mark on base of upper mandible (ns); cliff-nesting vs tree-nesting habit (1) (which, incidentally, may be related to apparently longer claws). Monotypic.
Andean valleys of WC Bolivia (SE La Paz and W Santa Cruz to SE Potosí and Chuquisaca).
