Distribution.

So far endemic to the Makay massif, Madagascar ( Manuel and Ramahandrison 2020).

Habitat in study area

(Fig. 2D-G, I-N ). This species was collected only at inner massif sites, in both south-central and northern Makay, where it is by far the most common and abundant species of aquatic Adephaga . It was found in a wide diversity of lentic water bodies (puddles, pools, ponds, a blind river channel, etc.), isolated or with slow water renewal, as well as in very slowly flowing streams. The surrounding environment was forested or semi-forested and free from anthropisation. These habitats were further characterised by sandy bottom (sometimes with stones), various amounts of plant debris, clear water (but often with orange masses of iron bacteria), and marginal vegetation absent or poorly developed.
