Although there was no prior discussion in the Taxonomy forum, I see that the subclass Acari (Mites and Ticks) has had a major overhaul at BugGuide, with the addition of about 100 new Guide pages. The full taxonomic tree now looks like this
Most of the changes are in the superorder Acariformes, which now lists 3 orders, 16 suborders, and 84 superfamilies. Almost all of the new pages contain no photos. For example, a browse through the suborder Brachypylina
shows 4 pages of superfamily names but no photos.
The names were apparently copied from the "Acari Project" whose links on this page
lead to lists of worldwide taxa and numbers of genera/species. It appears to be a good reference for nomenclature and taxonomy, although I don't know which (or how many) of its listed taxa occur in North America.
Linking to the "Acari Project" seems reasonable, but I see no point in creating empty pages which add more complexity to BugGuide while serving no purpose. Therefore, I suggest that all Acari pages currently lacking photos be removed, and that future pages be added only as needed - which is how BugGuide has always operated.
