Diagnosis. Panurginus herzi is typical for the group of species with shagreened metasomal terga, wide gonostylus, penis valve shortly bulbous and S6 ventrally with postero-lateral hair tuft. From other species of the group it can be differentiated by combination of the following characters: labral plate trapezoid, slightly narrowed apically; scutum on periphery delicately shagreened, medially tessellated or smooth, with pits 1−2 diameters apart; metasomal terga with shallow punctures; middle basitarsus of male 4−4.5 times as long as wide. Male S6 with apical elevation rectangular, straight, narrowly pubescent (Fig. 52).

Geographical distribution. Russia, Siberia [*Altai, *Tuva, Kemerovo Oblast ( Sidorov, 2010), Yakutia ( Morawitz, 1891)], * Mongolia (Uvs). Europe [ Austria, Germany, Switzerland, Montenegro, Macedonia, Bulgaria ( Warncke, 1972, as P. tyrolensis ; Schwarz, Gusenleitner, 1997)]. Mountainous except in Yakutia.
