Trachys subglaber Rey, 1891
Probably indistinguishable from the mine of T. troglodytes.
Caprifoliaceae, ? oligophagous
Because of confusion with T. troglodytes the list of host plants is unreliable. According to Levey only Succisa comes into consideration.
Not known from the Benelux countries(Fauna Europaea, 2016).
distribution within Europe
From Germany till Spain (Fauna Europaea, 2016); also Great Britain (Levey).
Trachys compressus Abeille de Perrin, 1891; Trachys troglodytes subglaber.
The Fauna Europaea considers subglaber a subapecies of troglodytes, but because in the UK, according to the experience of Levey, both species might co-occur this is improbable.
