Although labeled as "bismutomicrolite", the Microlite Group mineral at the Quixaba pegmatite was determined to be fluornatromicrolite as described in 1998, but not published until 2011 due to the revised nomenclature of the Microlite Group and Pyrochlore Supergroup. This specimen is from the type locality. Ex. Paulo Matioli collection.
