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.
