List of species & taxonomy

This genus includes the following eight species:

  • Entimus arrogans Pascoe, F.P., 1872
  • Entimus granulatus Linnaeus, 1758
  • Entimus imperialis (Forster, 1771)
  • Entimus excelsus (Viana. 1958)
  • Entimus serpafilhoi Morrone, Abadie and Godinho Jr., 2019
  • Entimus nobilis Olivier, 1790
  • Entimus splendidus Fabricius 1792 - synonym Entimus fastuosus Olivier, 1790
  • Entimus sastrei Viana 1958

The following cladogram represents the diversification of Entimus genus according phylogenetic analysis based on external morphology. It shows two vicariant events, where E. arrogans (Mesoamerican) diverged from South American species. Later, E. granulatus (Amazonian).[1][2]
