Cebrennus kochi (O. Pickard-Cambridge, 1872) : Zamani et al. 2014: 365 (misidentification).

Material examined. IRAN: Bushehr Province: 1 female, Bushehr, Chah-Kutah, 29°03'N 51°08'E, November 2013, M. Jahan leg ( JAZM).

Remarks. The shape of the female copulatory organ ( Figs 3 A, B) is indeed similar to that of C. kochi (cf. Jäger 2014, figs 1–6), however both species differ in some traits, including the eye arrangement. For instance, the posterior row of eyes is straight in the Iranian species ( Fig. 3 C), whereas it is strongly recurved in C. kochi . Moreover, the epigynal septum of the Iranian specimen lacks the characteristic transversal ridge in the posterior half (cf. Jäger 2014: figs 1, 4). Since characters of the female copulatory organs are not sufficiently diagnostic, the species cannot be fully assigned to any described species or be described as new to science until the conspecific male would be sampled and studied.

Distribution and habitat preferences. The single specimen was collected during daytime from a sandy dune habitat in southern Iran ( Fig. 4 ), with the majority of plants belonging to Acacia .
