Yahyapour, Eliye, Shayanmehr, Masoumeh, Vafaei-Shoushtari, Reza & Arbea, Javier I., 2022, New species and records of Neanurinae (Collembola: Neanuridae) from Mazandaran Province (Northeastern Iran), with a key to Iranian species of the subfamily, Zootaxa 5087 (2), pp. 253-274 : 272-273

Key to the recorded Iranian taxa of Neanurinae
