The 34 species currently recognized within the Pseudobunaea genus all occur in sub-Saharan Africa. In the last decade, many 'new' species have been described. Sometimes it seems that every mountain in Tanzania has its own species. How many of these will be valid remains to be seen. This is a complicated genus with variable species many of which look very similar. Correctly identifying some of them isn't always easy and all these new species are not helping at all.
However, even though the adults are often similar looking, there are obvious differences within the caterpillars. Unfortunately, except for a handful of species, most have never been reared. It would be useful to see more of the larvae.
