Telson gland observed in the genus Superstitionia

Rolando Teruel and co-workers have recently observed a telson gland in the genus Superstitionia Stahnke, 1940 (Superstitioniidae) for the first time. The gland is only found in males. The gland is presumed to have an exocrine function.

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.
