A detailed study of bisexual populations of stick insects collected near Samandaḡ (southern Turkey) showed that the brown females were Ramulus turcus (Karabaḡ), while males and greenish females morphologically corresponded to R. libanicus (Uvarov) from Mount Carmel. The identity of these two taxa was further supported by egg morphology and structure, which agree with earlier descriptions of R. libanicus. Karyological analysis furthermore showed a chromosome set of 2n = 30 with an XX‐XY sex‐chromosome mechanism which is unusual for stick insects and has never been described before among Ramulini. This supports the identity of R. turcus and R. libanicus and we conclude that these Turkish and Mount Carmel stick insects belong to the same bisexual species and that its name should be R. libanicus (Uvarov).
