The island nation of Madagascar was surveyed extensively through a series of expeditions to determine the fauna of Naucoridae.Previously, 17 species in four genera had been reported from the country.All taxa previously recorded from Madagascar were re-collected, with the exception of three species, Macrocoris flavicollis Signoret, Temnocoris starmuhlneri Poisson, and Tsingala nossibeanus (Bergroth).

is described; Temnocoris and Tsingala are revised; three new species are described in Temnocoris (T.leachin.sp.

, T.montandonin.sp.

, T.poissonin.sp.

) and four in Tsingala (T.angulatan.sp.

, T.latiforman.sp.

, T.spatulatan.sp.

, T.trilobatan.sp.

).Lectotypes are designated Switch Mat for Afronaucoris madagascariensis (Montandon), Tsingala humeralis (Signoret), and T.naucoroides (Montandon).

In Macrocorinae, a new species of Macrocoris, M.namoronan.sp.
