Remarks. Macrosiagon lyauteyi is similar to M. trinotata by the shape of body and elytra and by having the transversal linear impression in the posterior half of the pronotal disc (rarely indistinct in some specimens). However, it differs from it by the shape of the vertex ( Fig. 38 ) and by the lighter coloration.

Distribution. Described and known so far only from Madagascar.
