The charaxines do not have a distinct modal number. Their chromosome numbers are in the range n = 6-50, with n = 7-9, n = 12, n = 16, n = 19-21, n = 26, and n = 28-31 being the most common numbers. Within the Morphinae, the Morphini have a modal n = 28 and the Brassolini a modal n = 29, with few exceptions. The Neotropical satyrines, in particular the basal species, have a weak modal n = 29, which is a strong modal number in Palearctic satyrines. The African satyrines have an equally strong modal n = 28. Most Neotropical satyrines have, like charaxines, chromosome numbers lower than the weak modal n = 29, and often half this modal, but there are genera with stable numbers among the satyrines and charaxines. Evidently, the Neotropical satyroids descend from basal Nymphalidae with the typical lepidopteran modal number of n = 31, which have also given rise to the Heliconiini with modal n = 31 and 21 and Ithomiinae with modal numbers of n = 14-15. 收起
