Stempellinella ivanovae Giłka et Zakrzewska, 2014

Stempellinella ivanovae Giłka et Zakrzewska, 2014 : Zakrzewska & Giłka 2014: 338 (adult male; Eocene Baltic amber, Rovno).

Material examined. Adult male (tarsi of left legs separated or not visible) preserved in 50 x 20 x 12 mm piece of amber (Eocene, ~45–40 Ma, Baltic amber, Gulf of Gdańsk; MAI-1140); animal syninclusions: Diptera (numerous ind.): Chironomidae , Ceratopogonidae , Psychodidae , Empididae + Thysanoptera (1 ind.).

Remarks. The structure of the hypopygial anal point, the presence of the short nipple-like process on the gonostylus, the wing venation pattern (except the presence of a thin and semitransparent vein R2+3) are the characters found in the presently examined individual, which indicate the recently described species— Stempellinella ivanovae . Unfortunately, the remaining diagnostic structures are too weakly observable to complement description of the species (see Zakrzewska & Giłka 2014).

The total number of all known Stempellinella increases now to 22 (see the list below), including the three fossil and 18 extant species listed by Ekrem (2007) + 1 species presently proposed to be transferred from the genus Stempellina Thienemann et Bause, 1913 . S. sofiae , known from adult male ( Fusari & Lamas 2014), fits the generic diagnosis of Stempellinella , including several crucial characters discussed above (e.g. gonostylus distinctly shorter than gonocoxite; superior volsella rounded, extensive), thus is listed in a new combination.
