2015a Tanytarsus glaesarius Giłka and Zakrzewska in Zakrzewska and Giłka, p. 353, figures 5, 6 (male).

Material examined. Two adult males (syninclusions) in 8.5 x 8 x 3.5 mm piece of amber ( Eocene , ~40-45 Ma, Gulf of Gdańsk; CCHH 213-4 , Figure 1 ) : 1 male (tarsi of fore legs and left hind leg missing), 1 male (complete specimen).

Remarks. As Tanytarsus glaesarius was described recently on the basis of a single specimen, the original description can now be supplemented with the following characters: wing length 1140 μm, AR 0.98 (when flagellum measured as 10-segmented), AR 0.79 (as 11-segmented) (cf. Zakrzewska and Giłka, 2015a).
