This species was originally described as Iulus profugus from the area between Tomsk and Kansk ( Stuxberg 1876a , b), later transferred to Sibiriulus Gulička, 1963 ( Lokšina, Golovatch, 1979 ), redescribed based on material from both the Novosibirsk Area and the Republic of Khakassia ( Mikhaljova, 1993 ), and finally it was sunken as a senior subjective synonym of Cylindroiulus ( Sibiriulus ) dentiger Gulička, 1963 ( Mikhaljova, 2002 ), a form described from the Kemerovo Area ( Gulička, 1963 ). Being the most widespread species of Sibiriulus , this species is presently known from the Tomsk , Novosibirsk and Kemerovo areas, the Altai and Krasnoyarsk provinces, the republics of Altai and Khakassia ( Stuxberg, 1876a , b; Gulička, 1963 ; Byzova, Chadaeva, 1965 ; Mikhaljova, 1993 , 2002 , 2004, 2017; Mikhaljova, Golovatch, 2001 ; Babenko et al ., 2009 ; Nefediev, 2002a , b, 2018b; Mikhaljova, Nefediev, 2003 ; Mikhaljova et al ., 2007 , 2014 ; Nefediev, Nefedieva, 2007a , b, c, 2011, 2017).
