A new tungstophosphate mineral was found on dumps of the Le Mazet wolframite-bearing quartz vein of the Les Montmins mining district (Échassières, Allier, France). It was not yet found at the nearby, very mineral-rich Ste Barbe vein. The new mineral forms very small, bright yellow to orange-yellow, pseudo-octahedral crystals, indistinct corroded tabular crystals and anhedral grains. The mineral, which shows a vitreous lustre, sits in small voids of a dark pink-grey, fine-grained quartz matrix. The colour of the mineral is somewhat reminiscent of that cyrilovite which also occurs at the locality.
