Pigs, Peccaries and Hippos Status Survey and Action Plan (1993) www.iucn.org/themes/ssc/sgs/pphsg/APIntro.htmThese sentiments can be illustrated by the recent 'elevation' of two 'new' species of Sus, both endemic to the Philippines. These are the Visayan warty pig (S. cebifrons) from the West-Central Visayas Islands and the East Philippines' warty pig (S. philippensis) from Luzon, Mindanao and associated islands. Following Sanborn (1970), both of these taxa were assigned to S. celebensis until Groves (1981) reassigned them as endemic subspecies of S. barbatus. However, following the acquisition of additional skulls and mandibles in 1990, Groves (1991) suggested these were actually sufficiently distinct to merit full species status; a view which has recently (too recently for the full results to have been incorporated in this volume) been strongly endorsed by de Haan et al. (in press) on account of their lower chromosome number (i.e. 36, as opposed to the 38 typical of other members of the genus) and other cytological characters. |

The recently recognized Visayan warty pig is already extinct on two islands (Cebu and Guimaras) and endangered on the only other islands (Negros and Panay) on which it is known to occur. As a result, this species is now rated as one of the most endangered of all wild suids.

Sus cebifrons cebifrons Subspecies of the Visayan Warty pig. Became extinct in the mid 1990s. "S. cebifrons has been eliminated from three of the six islands where it was known or presumed to have occurred formerly; i.e. Cebu ( where the species was last reported in 1960s), Guimaras and Ticao Islands. It is also close to extinction, if not already ?functionally extinct?, on Masbate, where the species was last confirmed in 1993, at which time only a few individuals were reported to survive in one location. Consequently, potentially viable populations now survive only in the last remaining forest fragments on Negros and Panay Islands (collectively comprising c. 6% and >4% of land area, respectively). though genetic contamination via hybridization with free-ranging domestic or feral pigs has also been confirmed as occurring in most (perhaps all) of these populations (Oliver, 1993a, 1995, 2001)." --- "Oliver, W.
