Type locality. India. Material examined. 1 ♂ , 1 ♀ : MAK-11B. Distribution. Southern half of the Palearctic region, Africa, Oriental region ( Guignot 1959-1961 ; Miller 2002 ). In Madagascar, widespread. Habitat in study area (Fig. 2P ). This species was collected at a single site in central inner Makay, in an isolated shallow temporary puddle located in the middle of a large flat accumulation of sand in the outer part of river meander. The environment was totally open with no trees, the water was turbid and there was no vegetation. These habitat characteristics are very representative of the ecology of members of the genus Eretes everywhere in the world ( Miller 2002 ). Tribe Hydaticini
