New species of the genus Rhopalotettix Hancock, 1910 (Orthoptera: Tetrigidae, Metrodorinae) from Vietnam

S.YU. Storozhenko

Abstract. Rhopalotettix vietnamensis sp. nov. is described from Vietnam. The new species is similar to R. chinensis Tinkham, 1939 in a distinct median carina of the fastigium (in all the other congeners, median carina is absent) and differs from the latter species by the rostrum with almost parallel lateral sides and by a narrow tegmen, visible part of which is 2.3 times narrower than mid femur (in R. chinensis, rostrum with the lateral sides gradually converging to the acute apex, and visible part of tegmen is almost as broad as mid femur).
Key words: pygmy grasshoppers, taxonomy, Vietnam, Orthoptera, Tetrigidae, Metrodorinae, Rhopalotettix, new species
