For a wikispecies, I would expect to be able to click on the Kingdom (Animala), Phylum (Chordata), Subphylum (Vertebrata), and so on so I can narrow down progressively to homo sapiens, homo neanderthalensis, homo erectus, etc., and on the each further down level (i.e. Chordata, then Vertebrata), the most notable species would have higher links on that page. Is that what you mean by category?

Start at http://en.wikipedia.org/wiki/Category:Animalia and keep working down the subcategories for examples.
A typical category chain goes:
(Fundamental -> Knowledge -> Science -> Natural sciences -> Biology -> Life) -> Animalia -> Chordates -> Mammals -> Carnivora -> Canines -> Dogs -> Dog breeds -> (185 articles about dog breeds)
My wikitime this week has been categorizing all mammals in a sensible fashion. The chosen categories (typically at the KPCO and F levels) have been extensively thought out at [[Wikipedia_talk:WikiProject Tree of Life]] so comments are welcome there.
