DISTRIBUTION. * Russia (Altai Rep., Khakassia Rep., Krasnoyarsk Terr.) ;

Central Europe, Pseudochrysis fahringeri is an Euro-Siberian species; in Europe is very rarely collected and occasionally found only on mountainous steppe areas ( Wallis,

Switzerland) and on mountains in Central Europe (Leitha Mts., an offshoot of the

Alps and a connection to the Carpathians, and at Marchfeld), which serve as refugees.

The distribution is still poorly known due to the confusion of P. fahringeri with P.

incrassata; e.g. Linsenmaier (1959) initially considered P. fahringeri as the true P.

incrassata.

REMARKS. Pseudochrysis fahringeri has been considered as valid species

(Linsenmaier, 1997), subspecies (Trautmann, 1926) or synonym of P. incrassata

(Kimsey & Bohart, 1991) by different authors. P. fahringeri is a well distinct species, easily recognizable by the large dimensions (up to 11–12 mm); TFC raised and complete, medially straight (vs. almost vanishing in P. incrassata ), subantennal space elongate (2 MOD) (vs. short, 1.4 MOD); T2 with distinct double punctuation and larger punctures separated (1–2 PD apart), with tiny punctures on interspaces:

tiny punctures become denser and contiguous on lateral and posterior margin (vs.

punctuation all over uniform, with dense and contiguous punctures); apical margin of T3 extended after pit row ( Fig. 6E ) (vs. not extended ( Fig. 7C )); shape of male genital capsule ( Figs 7E vs. 7G) and female internal urites (Figs 8C, F, I); coloration of mesosoma consistently dark blue ( Fig. 2E ) in female (vs. blue with reddish areas). It can be separated from P. gengiskhan for the dark mesosoma coloration

(greenish to golden in P. gengiskhan ); apical margin of T3 extended after the pit row (vs. not extended); black spots on S2 large (vs. smaller); genital capsule and female internal urites.
