In this note, we record for the first time the occurrence of a telson gland in the monotypic genus Superstitionia Stahnke 1940 (Scorpiones: Superstitioniidae). The putative gland is marked by an elongated patch of wrinkled cuticle restricted to the dorso-apical surface of the telson vesicle of adult males, and is absent from females and immatures. Similar presumed glandular structures have been observed in a number of other scorpions, including many South American Bothriuridae, and the recently defined vaejovid genera Chihuahuanus González-Santillán et Prendini, 2013 and Maaykuyak González-Santillán et Prendini, 2013.
