Distribution: Southern part of Eastern Europe, south of Asiatic Russia; eastern Kazakhstan (Zemskaya 1973; Senotrusova 1987; Nikulina 2004). In Asiatic Russia, H. eversmanni inhabits some areas of southwest Siberia and southern parts of Primorye, Russian Far East (Davydova & Nikol’skiy 1986; Nikulina 2004).
