The two only known specimens for Sillem's Mountain-Finch were
collected in September 1929, during the Netherlands Karakorum Expedition, by J.A. Sillem.
They were then identified as L. brandti.
The skins reside in ZMA, Amsterdam.
Birds to Watch 2 considers this a "data deficient" species.

The authors do not provide an analysis of relationships between species in the Amaurospiza group, so I have tentatively placed A. carrizalensis between concolor and moesta.
