Remark. Colletes kaszabi and C. uralensis Noskiewicz are closely related and both have been rarely collected so their individual variation has been little understood. As a part of the present project it was possible for the first time to study a larger number of specimens of both species making us aware that misidentifications have occurred in the past and that a female of C. kaszabi (instead of C. uralensis ) was used earlier for illustrating keys for species identification ( Kuhlmann & Proshchalykin 2011: Figs 7 b, 8c, 20c, d; Kuhlmann & Proshchalykin 2014: Figs 5 b, 7b, 27c, d). To facilitate their identification we provide images of females ( Fig. 2 ) and males ( Fig. 3 ) of both species and and present updated distribution maps ( Fig. 4 ). Colletes uralensis generally has a more southwestern distribution than C. kaszabi that is centred in Mongolia and neighbouring parts of Russia and China ( Fig. 4 ). Previous records of C. uralensis from Russia ( Kuhlmann & Proshchalykin 2011, 2014) turned out to be C. kaszabi , so C. uralensis had to be removed from the list of species known to occur in Russia.

Osytshnjuk et al. (1978) reported C. uralensis for the European part of Russia but neither was locality data provided nor could specimens be found in any collection so we assume that this record was merely based on assumption rather than a specimens.

A male C. uralensis mentioned by Noskiewicz (1936: 255), "von Kozlow am 21/VII. 1900 am Alasz-Fluß erbeutet" (collected by P. Kozlov at Alasz river 21.vii.1900) was checked and turned out to be collected in 1909, not 1900, when P. Kozlov was in the Alashan desert, eastern part of Etszin-gol river, at Chzhargalante near Kharo- Khoto (41°45´N 101°05´E), which is in present day China ( Kozlov 1923).
