Notes on a small collection of Prioninae from North-East Madagascar with the description of a new Schizodontus/ Quentin amp; Villiers, 1974 (Cerambycidae, Closterini).

We present observations from a small collection of longhorns belonging to the subfamily Prioninae and collected during an expedition in the rainy season to a newly designated protected area, Mahimborondro, in North-East Madagascar. The material includes a new species (S. mahimborondroensis sp. nov.) of Closterini (Prioninae) from a small genus with only two described species (Schizodontus angustus Quentin Villiers, 1974 and S. latus Quentin Villiers, 1974). An identification key to the three species is included.
