A new species – Dactylolabis (Idiolabis) ryszardi n. sp. from Eocene Baltic amber is described. It is the third species of this extinct subgenus to be described and is known exclusively from Eocene Baltic amber. The distinctive features of the newly described species are the character of wing venation, especially the shape of discal cell, characteristically indented in upper distal corner by the position of dM1+2 shifted to 1/3 of d-cell, and the morphology of the hypopygium. A parsimony analysis of type species of extant taxa and extinct species of the genus Dactylolabis from Baltic amber is provided based on 25 morphological characters. The analysis confirms the status of extinct subgenera from the Eocene Baltic amber currently recognized within the genus Dactylolabis and shows the modern and fossil taxa grouped separately.
