Steneotarsonemus graminis (Krämer, 1886)
The inside of the leaf sheath and the corresponding part of the culm covered with rows or crusts of initially white, later brown, papillae.
Buhr cites the species name between quotes, and the Fauna Europaea (2013) does not mention the name, although it certainly exists. The interpretation of the name therefore is somehwat unsure.
