According to current knowledge, the number of known species is lower due to systematic combinations other than original or doubtful status of some names ( nomina dubia ). Stempellina includes 15 described species: 2 extinct and 13 extant ( Giłka 2005 , Zakrzewska et al. 2020 ), thus its share in the tribe’s world extant fauna is less than 2%. Stempellina are recorded in all continents except Antarctica , mostly in the Holarctic. In North Korea , one unknown species has been found.
