Actually, the splittings is not completed yet, I think. PSC is trying to minimise subspecies taxon, even "erase" it, and to state species as monotypic. It is obviously done with most of the species (taxons are reduced from 430 to 348 in Bovidae), but in this matter, there is a feeling, that accounts is dependable of author. All account's authors in Bovidae, mention in the beggining of the book.
Nevertheless, book is exceptional. We all desired more subsp. info before:
Here it is.Even some subsp. are questionably combined in one taxon , but this looks DNA proofed(citation needed).
No matter, that science will recognize Groves approach, or not (this happend in Primatology) we have most comprehensive Ungulate guide, ever written.
Personally, I regret, that authors of Cervidae are not so brave. We can expect new splits in Ungulate Taxonomy, but they would not be so beatifully illustrated. Regret also, that Northern White is only mentioned in Family text, as a species(we knew that from lynx page). It can be wonderfull symbol of PSC conservation role.(Groves recognize it as species in "Sixth Rhino")
I hoped citation in text also, like Walker's 6th, but you can find some names only in accounts. There is opinion that Gaur is not the largest cattle.Badly need record history of this statement. The "feral story" whit Kouprey is interestingly resolved.
Highly agree with briefly description of Giraffe vs. Elephants for example.
Newest genetic analysis show differences from 0.5 to 6.9% , below those required for the establishment of distinct species Giraffe, they say. Here, I also wait "Ungulate Taxonomy".
Pictures are very informative. In some, like newest HBW vols, are mentioned subsp. I was stunned from Western Iberian Ibex, sitting on the almost vertical rock, and from Salt's Dik-dik loused by Velvet Monkеy.
I saw 1 new species described B
