Diagnosis

(only male known). Similar to Merodon vandergooti from which differs by all femora completely reddish yellow (Figs 4 E View Figure 4 , 20 B View Figure 20 ), while in males of M. vandergooti pro- and mesofemora are partly orange-yellowish and metafemur is almost completely black (Figs 4 C View Figure 4 , 20 D View Figure 20 ), a less curved metafemur (Fig. 4 E View Figure 4 ), and an elongated anterior surstylar lobe in M. rufofemoris sp. nov. (Fig. 11 A View Figure 11 : al) (shorter in M. vandergooti ; Fig. 10 A View Figure 10 : al). It differs from M. aenigmaticus sp. nov. by the reddish yellow femora (Fig. 4 E View Figure 4 ) (partly black in M. aenigmaticus sp. nov.; Fig. 4 G View Figure 4 ), and the posterior surstylar lobe angulate ventrally (Fig. 11 A View Figure 11 : pl) (rounded in M. aenigmaticus sp. nov.; Fig. 9 A View Figure 9 : pl).

Anterior surstylar lobe large, elongated (~ 3.5 × longer than wide) and sickle-like (Fig. 11 A View Figure 11 : al); posterior surstylar lobe rectangular (Fig. 11 A View Figure 11 : pl, marked with red arrow); cercus rectangular (Fig. 11 A View Figure 11 : c); hypandrium sickle-shaped, without lateral projections; lingula short, with tapering but rounded tip (Fig. 11 C View Figure 11 : l).

Female. Unknown.

Distribution and biology.

This species is only found in the Fars Province of Iran (Fig. 13 View Figure 13 ). This Iranian locality lies within the Zagros Mountains forest steppe ecoregion ( Olson et al. 2001), representing an arid and semi-arid forest ecosystem with Quercus brantii as the dominant vegetation type ( Azizi Jalilian et al. 2020). Flight period: May. Developmental stages: undescribed.
