Arguably the most exciting concept in the entire field of
zoology is the thought that new large terrestrial tetrapod
species await discovery. And despite statements from journalists
and scientists, history demonstrates that the continued
discovery of such animals is not an extraordinary or unexpected
event. You will know this if you are familiar with such animals
as the Saola Pseudoryx nghetinhensis (named in 1993), Giant
muntjac Megamuntiacus vuquangensis (named in 1994), Truong Son

putaoensis (named in 1999), Dingiso Dendrolagus mbaiso (named in

(named in 1996), Arunachal macaque Macaca munzala (named in
2004) and Kipunji Rungwecebus kipunji (named in 2005). Several
studies have emphasized the fact that new terrestrial mammal
species are not uncommon (Heuvelmans 1983, Pine 1994, Patterson
2000, 2001, 2002, Collen & Gittleman 2004), and it is not true
that all such taxa are small-bod
