Diagnoses: Euroleon species are distinguished by their characteristic patterns on wings, head, pronotum and anal cross veins. They have spots in their anterior half of the forewing membrane, while Euroleon nostras has a distinct spot near the end of Cup+1A in the posterior half of the forewing. Anal cross veins are divided after A2+A3 vein, creating two rows of cells in E. parvus, but they are almost non-existent in E. nostras. The costal area of E. nostras has some forked cross veins before the pterostigma, while they are entirely simple in E. parvus.
The pronotum of E. nostras is entirely black, but divided by a yellow central line (Fig. 7). The pronotum of E. parvus is characterized by two black trapezoidal patterns each having a yellow circular marking in the anterior half and yellow lateral margins patterns (Fig. 8). Features of the face and vertex for E. nostras and E. parvus are shown in Figures 16 and 17.

Distribution: widespread in Palaearctic Region, Iran (Hölzel, 1972: Assalem)
Comment: The species was reported from Iran by Hölzel (1972) based on a single female specimen, but later it was characterized as a boreal species leading to its exclusion from the Iranian antlion fauna (Mirmoayedi et al. 2015). Our study suggests that the distribution of this species in Iran is restricted to the Caspian Coast province of Mazandaran.
