10. Panurginus muraviovi sp. n.

Diagnosis. Bees of the new species are very close to Panurginus niger Nylander , from which differ by the labral plate at male triangular ( P. niger : round) ( Fig. 74 ); scutum and scutellum glossy, with pits of different sizes a few diameters apart, 1−5 pit diameters at male and 2−7 at female ( P. niger : slightly shagreened, 0.5−2 and 1−4 pit diameters respectively); male S6 narrower, 1.2 times wider than long ( P. niger : 1.5); with apical arch deeper, 1.6 times wider than deep ( P. niger : 2) ( Fig. 73 ). Body length: male 5 mm, female 5.5−6.5 mm.

Etymology. Nikolai Nikolaevich Muraviov-Amurskiy (Russian∶ Николай Николаевич Муравьёв­Амурский﹔ 1809–1881) was a Russian statesman and diplomat, who played a major role in the expansion of the Russian Empire into the Amur River basin and to the shores of the Sea of Japan. Muraviov was the first governor to propose Tsar Nicholas I to abolish serfdom; a motion signed by nine local land-owners. For the period of 13 years, a general governor of the eastern Siberia Muraviev worked hard for the sake of the local community and entire nation.
