Germany (Fauna Europaea, 2008).
Frontal appendage present. Front spiraculum with 9-11, rear spiraculum with 14-15 papillae. Mandibles with only one tooth. (The mandibles differ in size, causing one tooth to be slightly shifted with respect to the other; seen from the side this may give the appearance of two teeth!)
