Parathalassiinae

Parathalassiinae is a subfamily of flies in the family Dolichopodidae. It is part of an extended concept of the family, Dolichopodidae sensu lato, and forms a monophyletic group with Dolichopodidae sensu stricto. It was once placed provisionally in the subfamily Microphorinae as the tribe Parathalassiini.

According to a molecular phylogenetic analysis of the family Dolichopodidae by Germann et al. (2011), there is strong evidence for placing Parathalassiinae within Dolichopodidae sensu stricto.
