Alcock divides the family Xanthidae into two sections, 
the first comprising the sub-families Xanthinae, Actaeinae 
Chlorodinae, the second the sub-families Menippinae, Oziinae, 
Pilumninae and Eriphiinae. For the Actaeinae he gives the 
following character, “‘Carapace usually much broader than 
long, and usually very profusely and profoundly lobulated ; 
the anterolateral border is either divided into four blunt lobes 
or crenated. The front is about a third the greatest breadth 
of the carapace, sometimes a little more, sometimes a little 
less, and is divided into two rather prominent usually round- 
pointed lobes.”
