Criorhina ranunculi ( Panzer, 1804)

Fig. 2

Examined material. IRAN, North Khorasan province: 1 ♂, Dasht , 37°18′N 56°00′E, 990 m, 16.v.1993, leg. A. Pazuki / M. Badii.

Remarks. The species C. ranunculi can be separated from other Criorhina species by the following combination of characters: katepimeron pilose; scutum and basal half of abdomen covered with blackish pile; hind femur strongly enlarged and swollen; hind tibia distinctly swollen; abdominal tergites lacking transverse fasciae of pollinosity; male genitalia as in Vujić & Milankov (1999: figure 1). The genus Criorhina was first recorded from Iran by Van Steenis & Gharali (2015) as C. portschinskyi ( Stackelberg, 1955) . In the present study, both Iranian species of Criorhina were found: C. portschinskyi , in May, in the north of Elburz Mountains, at low altitudes, near the Caucasus (western Iran), and C. ranunculi , in Turkmenistan (eastern Iran). In the Palaearctic region, C. ranunculi is widely distributed in Europe eastwards to European parts of Russia ( Vujić & Milankov 1999; Speight 2016).
