Fennica 23: 127—139. Morphology and acoustic signals of four species of the subfamily Gompho- cerinae (Orthoptera: Acrididae) from Turkey are studied. Eremippus zeybekoglui M01 sp. n. is described from Northern Anatolia. Gomphocerus transcaucasicus Mistshenko, 1951, stat. n. is considered as a distinct species, not a subspecies of Gomphocerus sibiricus (Linnaeus, 1767). Previously unknown male of Dasy— pippus uvarovi Karabag, 1953 is described. A. M01, Guzelyurt Vocational School, Aksaray University, Aksaray, Turkey.
