ABSTRACT
Four new Laccophilus species are described from Madagascar, three belonging to the L. alluaudi-group (Laccophilus leguyaderi sp. nov., endemic of the Andringitra massif, L. bergsteni sp. nov., endemic of central highland mountains, and L. makay sp. nov., endemic of the Makay massif) and one belonging to the L. laeticulus group (L. rakouthae sp. nov., endemic of the Ankaratra massif). Habitus in dorsal and ventral views and male genitalia are illustrated for the new species (and for comparison, L. alluaudi and L. transversovittatus); furthermore, their habitat preferences and geographical distributions are described and illustrated. An identification key for all species of the L. alluaudi group is provided. The discussion is focused on the interest of the newly described taxa in the context of species radiations in Madagascar.

Canthyporus reebae sp. nov. is described from the south-eastern part of the Itremo mountain range and from the Andringitra massif in central eastern Madagascar. The new species is the second one of the genus Canthyporus Zimmermann, 1919 to be recorded from Madagascar, the other being C. pauliani Guignot, 1951, so far endemic to the northern massif of Tsaratanana. The habitus and male and female reproductive structures of the new species are illustrated. Canthyporus reebae sp. nov. differs from C. pauliani notably by larger size, less parallel-sided and more evenly convex habitus, paler pronotum, more weakly impressed body surface reticulation, and a different shape of the median lobe of aedeagus. Differences with similar C. hottentottus-group species from mainland Africa are also discussed. Data on habitat preferences of C. reebae sp. nov. and a distribution map of Malagasy Canthyporus are presented and discussed.
