New members of the genera Neanura MacGillivray, 1893 and Deutonura Cassagnau, 1979 (Collembola: Neanuridae) from the Middle East

New species of Neanura MacGillivray, 1893 and Deutonura Cassagnau, 1979 are described from northern Iran. Both taxa are characterized by unusual features that place them in isolated positions within the genera. Neanura deharvengi sp. nov. differs from congeners by the extreme reduction of head chaetotaxy and fused lateral tubercles on the head. These characteristics of the new species broaden the existing diagnosis of the genus Neanura. An updated diagnosis is provided herein. Deutonura persica sp. nov. is most similar to D. plena (Stach, 1951), known from the Carpathians. The new species can be distinguished by the strong reduction of its head, labial, and labral chaetotaxy as well as the relative length of chaetae De2 and De3 on abdominal segments I–III. The Iranian records of D. decolorata (Gama & Gisin, 1964) are questioned. Brief remarks on the importance of the newly described species for the knowledge of both genera are also provided
