Telmatogetoninae
Intertidal Midges
Telmatogetoninae is a subfamily of non-biting midges (Chironomidae) primarily adapted to intertidal marine and brackish water environments. The subfamily contains two genera: Telmatogeton and Thalassomya. Larvae exhibit specialized physiological adaptations for osmoregulation and desiccation resistance, enabling survival in harsh, variable saline conditions of coastal habitats. Most species inhabit rocky shores, sandy beaches, and estuarine zones, though some members occupy freshwater torrent habitats.
