| The Afrotropical genus Dicronorhina Hope (= Dicranorrhina auctorum, unjustified emendation) is diagnosed and discussed. The characters of the species, subspecies and varieties are examined, and presented in a synoptic table and in an analytical key. An annotated checklist of the species, subspecies and varieties is given. Three species are recognized; in one species, five subspecies are recognized. Several varieties are discussed. Two new varietal names are proposed. A key to the genera of larger Afrotropical Goliathini with horned males is given. The phylogeny of the Dicronorhina species and their position among the other Afrotropical Coryphocerina is briefly discussed. |

| Seeds of all specimens of Montiafontana L. from several herbaria in the Netherlands were studied scanning electron microscopically. Four main seed types could be recognised (fig. 1,2), corresponding with the types often used for dividing the M. fontana complex in species, subspecies or varieties. These main types are connected by intermediates and together they form a series of gradual variation. No other characters could be found that show a correlation with the seed types. Hence the authors refrain from a formal infraspecific subdivision of M. fontana. |
