There's a results from GeoNames, "Marais de Torotorofotsy" for this coordinare, but it's not clearly visible, it's also not shown here. Torotorofotsy Marsh is a Ramsar site: https://rsis.ramsar.org/ris/1453 so worth marking here, both as 'Marais de...' and English 'Marshes'.

Possible connection with other locations or landscape features already mapped: "The Site lies within the Ankeniheny-Mantadia-Zahamena forest corridor, a high-priority area for conservation in east-central Madagascar. The marshes play an important role in flood control in the area of Andasibe Commune and feed the valleys with their abundant rice fields. They also provide domestic water for the villagers of Maromahatsinjo." (I quoted Ramsar website here)
