Notes on the synonymy of Myrmecophilus bifasciatus Fischer von Waldheim, 1846 (Orthoptera: Myrmecophilidae)

Myrmecophilus bifasciatus Fischer von Waldheim, 1846 was originally described based on a single specimen originating from Ukraine. The original description of M. bifasciatuswas evaluated, and compared with specimens of M. acervorum(Panzer, [1799]). The description and the illustration given in the original descriptiondo not indicate any difference between nymphs of those two species. Thus, M.bifasciatus has been recognised as a junior synonym of M. acervorum
