Genus: Stempellina Thienemann et Bause in Bause, 1913

So far, over 20 specific names have been ascribed to Stempellina as the genus, subgenus of Tanytarsus or to other Tanytarsini generic names. 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.
