Hydroglyphus plagiatus (H. J. Kolbe, 1883)

Type locality.

Eastern part of Madagascar.

Material examined.

1 ♂: MAK-17.

Distribution.

Madagascar, common in the Central Highlands ( Guignot 1959-1961; Bertrand and Legros 1971; Bameul 1984, Biström 1986; Rocchi 1991).

Habitat in study area.

This species seems very rare in the Makay since only one specimen was found, in an inner massif site located in a semi-forested environment. The habitat was a small, isolated, sun-exposed puddle on rock mass, on the bank of a river. The bottom consisted of sandstone, sand and clay without organic debris, the water was clear and there was no vegetation.
