Material examined. 1 ♂ , 2 ♀ : MAK-3; 2 ♂♂ , 8 ♀♀ : MAK-10; 1 ♂ , 1 ♀ : MAK-11B; 2 ♂♂ , 2 ♀♀ : MAK-12A; 1 ♂ : MAK-15; 1 ♂ , 1 ♀ : MAK-16; 9 ♂♂ , 1 ♀ : MAK-25A; 3 ♂♂ , 1 ♀ : MAK-29; 1 ♂ : MAK-35A; 1 ♀ : MAK-37A; 4 ♂♂ , 2 ♀♀ : MAK-39A; 1 ♂ : MAK-40B. Distribution. Madagascar (distribution within the island poorly known) ( Guignot 1959-1961 ). Habitat in study area (Fig. 2D, L, M, P ). We met this species only in the central part of inner Makay, mainly in puddles and pools with or without water circulation and in small streams, with clear or turbid water, sandy bottom (at some sites with gravel and stones) and moderate to abundant plant debris or tree roots, in forested or semi-forested environments untouched by anthropogenic disturbance.
