Undescribed or new species

The taxonomy within the Suidae is still changing with new insights from morphological and genetic analyses indication significant variation suggesting that certain taxa warrant allocation to species level. None of these new taxa are presently listed by the IUCN, but some could be highly threatened and may require urgent conservation attention. Below some of these new taxa are discussed.

A. Sus grovesi sp. nov. from the Sulu archipelago in the Philippines.

This species was described in 2003 in an unpublished manuscript by Karen Rose and Peter Grubb but their analysis remains to be confirmed through additional craniometric and genetic analysis.

B. Several proposed taxonomic changes in the Sus scrofa group. Colin Groves and Peter Grubb
recently published a significant revision of ungulate taxonomy, which includes several taxonomic proposals for the Suidae. Within Sus scrofa, they proposed the following changes:

(1) Sus moupinensis Milne-Edwards, 1871.  Burma/China. Synonyms as in Ellerman & Morrison-Scott (1951), plus canescens Heude, 1897, coreanus Heude, 1897, canescens Heude, 1897, meles Sowerby, 1917, collinus Heude, 1892 - and Sus bucculentus!

(2) Sus chirodontus Heude, 1888.  South-Central China. Synonymy as in Ellerman & Morrison-Scott (1953)

(3) Sus ussuricus Heude, 1888.  Heilongjiang/Far East. Synonymy as in Ellerman & Morrison-Scott (1953)

C. Note that the above proposal (B) combines the previously described Sus bucculentus with Sus moupinensis. Sus bucculentus is still listed on the IUCN Red List, but we will propose that it is included in S. moupinensis, and its conservation status reassesed.

D. Groves and Grubb in their 2011 book on Ungulate Taxonomy made several additional taxonomic proposals for the Suidae, including the following:

(1) Recognition of three species of Forest Hog: Hylochoerus meinertzhageni of the Western Rift Mts, Rwanda, E.African region; H.rimator: C.African region; and H.ivoriensis: W.Africa (Liberia to Ghana). Groves noted that the latter two are not strongly distinct, and need more study, but H.meinertzhageni is very different from the others.

(2) Elevation of Sus blouchi (former subspecies of S. verrucosus from Bawean Island) to full species level.
