Sensu lato

[Riaan Stals]

Dear All

How wide can one cast the net of "sensu lato"? I mean:

Consider two valid genera, A and B, which happen to be closely related. A is an old
and rather large genus, and B was erected for a couple of species previously
belonging to A more recently. Is it in order to refer: [i] to B;  [ii] to both A and B, as
"genus A sensu lato"?

Thanks for helping me out on this one.

With greetings from a hot and dry day in Africa,

RIAAN
