Extant pygmy grasshoppers (  Tetrigidae  ) that possess wings have the forewings reduced into scale-like tegmenula, while hind wings remain fully developed.    Rusmithia   gorochovi    gen. et sp. nov.  (  Tetrigidae  ,   Batrachideinae  ,   Rusmithini   trib. nov. ) is described based on a single adult female holotype from Lithuanian Baltic amber, from the Bartonian-Priabonian age, some 40 million years ago, and this is the only known tetrigid in which tegmenula or tegmina (the forewings) extend as far as half the length of the hind femur. Besides this very unique trait, other characters of    Rusmithia    gen. nov.  indicate similarity with extant and especially fossil   Batrachideinae   (genus    Danatettix    Thomas, Skejo &amp; Heads, 2019). Because of the strong differences this genus and    Danatettix    have with American   Batrachideinae  , they are assigned to a new tribe, European   Batrachideinae   or   Rusmithini   trib. nov.    Acrydium   bachofeni    (Zeuner, 1937) might belong to this or a sibling genus based on its very long tegmenula or    Succinotettix   chopardi    Piton, 1938, based on its 19-segmented antennae; neither species is tranferred as their types could not be examined.
