Taxonomy
The Javan and the Bawean warty pig (Sus verrucosus and
S.  blouchi, hereafter ‘warty pigs’ if both species are meant,
Figures 20.1, 20.2, and 20.3) are both endemic to the Indonesian
islands of Java and Bawean, respectively. The ancestry of warty
pigs in Indonesia has been traced back to several fossil pig spe-
cies of Java (Hardjasamita 1987). Combined with phylogenetic
data (Randi et al. 1996) this suggests that the Javan warty pig

has evolved on Java for about 2 million years. Using genomic
data, Frantz et al. (2013) conclude that the Javan warty pig is an
evolutionary significant unit and is most distant from all other
Sus species in South East Asia. The Javan warty pig has coexisted
with the new proposed species of European wild boar (S. vitta-
tus) on the island of Java since its arrival in the Late Middle–Late
Pleistocene around 70,000 years ago (van den Bergh et al. 2001).
In 2011, Groves and Grubb described the species Bawean warty
