Type specimens examined. None.
Other material examined. Ukraine: many specimens from its southern part, except the southern coast of the Crimea; Russia: many specimens from the south of the European part (to Kursk, Voronezh, Ulyanovsk and Orenburg in the north) and W. Siberia (foothills of Altai); Georgia, Armenia, Azerbaijan: many specimens; Turkey: 3 ♂, Anatolia, Dikman-Dagh; 3 ♀, Anatolia, Baraj; 1 ♂, 1 ♀, Anatolia, Mogan Gölü; 1 ♂, Anatolia, Yukaricanli; 1 ♀, Kars; 1 ♀, Kazikoporan; 1 ♂, Medjingert; Kazakhstan: many specimens from western, central and southern part; Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan: many specimens from foothills and mountains; Iran: many specimens (Tadjrish near Teheran; Gorgan; Shahkuh; Golshan); Afghanistan: 1 ♀, Badakschan, Barak. Diagnosis. Body length: ♂ 7.9-9.7 mm, ♀ 8.2- 10.2 mm (exceptionally, slightly more). General colour of dorsum usually paler than in the nominotypical subspecies, dirty yellow with obscure pattern; in such specimens, yellowish callose speckles are mainly concentrated on sides and less distinct than in the nominotypical subspecies. However, some specimens, for instance all specimens from the NW Caucasus, do not differ in the coloration of dorsum from the nominotypical subspecies. Antennal segments 1 and 2 usually red or yellowish red, but specimens with these segments brown or black occur as well, especially in the Caucasus.
Distribution. The steppe zone from Hungary to Altai and also the foothills and mountains of Transcaucasia, Turkey, Iran, former Soviet Central Asia, and Afghanistan.
Comments. The identity and status of P. conspersa (considered by us a subspecies of P. exanthematica) was among the main sources of confusion in the genus. Puton (1881a) misidentified this species, erroneously ascribed to it the main distinguishing character of P. granulata (antennal segment 3 half as long as 2), and this resulted in the description of P. affinis from the type locality of P. conspersa and the statement (Kiritshenko, 1951) that records of P. conspersa from Russia are erroneous. Eleven specimens from Sarepta, the type locality of P. conspersa, and many specimens from the adjacent areas are represented in the ZIN collection. All of them are conspecific and fit well the original description, which indicates the body length 9 mm and red coloration of the 3 basal antennal segments. S. albopunctata, P. affinis and P. argillacea were synonymized with P. exanthematica by Reuter (1885), Putshkov (1961), and Kerzhner (1964), respectively. Judging by the examined specimens from their type localities, they refer to ssp. conspersa rather than to the nominotypical subspecies. We did not examine specimens from Hungary, but the body size given for var. antennata (8-9 mm) is within the limits of variability of P. e. conspersa.
Comparison of this form with the typical P. exanthematica did not reveal any distinctions in the male genitalia, except that in smaller specimens also the genitalia are smaller. External characters are more or less overlapping (see the Table for measurements) and the two forms do not co-occur, though the range of P. e. exanthematica in the Near East is probably disjunct and of complicate configuration. This is the reason why we consider them to be subspecies.
