Type-material. Amydetes detrusa was described from specimens deposted at Bruch’s collection (Olivier 1907b). The type was cited from Uruguay: Maldonado. We chased this material in the collection of the argentine entomologist Carlos Bruch, actually split between Museo De Ciencias Naturales Bernardino Rivadavia and the Museo La Plata (Argentina). The material is present neither in these collection anymore, nor in the the Olivier's excollection, or any of the visited Instituions.

Comments. The original description did not allow us to properly identify any of the studied specimens as Amydetes detrusa . As we didn’t find the type-material of this species, we keep the originial description.
