Identification. This morphospecies can be distinguished from the other morphospecies of collected Canthidium by the presence of a cephalic carina with two projections in the form of protuberances towards the vertex; a clypeus weakly excavated towards the apex; pronotum clearly dotted and shiny; elytra striae strongly marked (pers. obs.).

Distribution. This abundant morphospecies (106 individuals), was found between 850–1200 m a.s.l. in the riparian forest, high secondary forest and wooded grassland. However, there was a clear preference for forest habitats, especially in the riparian forest relics (92 individuals). Although they were observed in the wooded grassland, it is likely a route of passage or they were acting like “tourists”, given their low abundance in this habitat (three individuals).
