Parathalassius
Parathalassius is a genus of long-legged flies in the family Dolichopodidae, subfamily Parathalassiinae. The genus name derives from Greek, meaning 'near the sea', reflecting its strict association with coastal habitats. The genus comprises 15 recognized species distributed across the Palaearctic and Nearctic realms, with nine species described from the Nearctic Region in a 2017 revision. Species are restricted to sandy marine coastlines, where they occupy beach and dune ecosystems.
