Introduction: first described from a locality in Hungary by the mineralogist J.J. Huot in 1841, 'wehrlite' has since been shown to be an intimately intergrown mixture of the bismuth telluride pilsenite and the silver telluride hessite, and is thus no longer a valid mineral species (Ozawa & Shimazaki, 1982).
Occurrence in Wales: the presence of the now discredited mineral 'wehrlite' was recorded in galena dominated gold-bearing veins at Clogau Mine by Naden (1988).
