Bubalina

Bubalina is a subtribe of wild cattle that includes the various species of true buffalo. Species include the African buffalo, the anoas, and the wild water buffalo (including the domesticated variant water buffalo). Currently, buffalos can be found naturally in sub-Saharan Africa, South Asia and Southeast Asia, and domestic and feral populations have been introduced to Europe, the Americas, and Australia.[2] In addition to the living species, bubalinans have an extensive fossil record where remains have been found in much of Afro-Eurasia.[3]

Genera
Synonyms
  • Buffelinae (Knottnerus-Meyer, 1907)

Despite being sometimes referred to as buffaloes, bison are not members of the Bubalina, but are instead classified in the subtribe Bovina.

Phylogenetic relationships of extant genera of the tribe Bovini (Hassanin et al., 2013)[4]

The majority of phylogenetic work based on ribosomal DNA, chromosomal analysis, autosomal introns and mitochondrial DNA has recovered three distinctive subtribes of Bovini: Pseudorygina (represent solely by the saola), Bubalina, and Bovina (which today are represented by the genera Bison and Bos).[4][5][6][7] One cytogenetic analysis concerning the phylogenetic position on the saola suggests the species could be related to buffalo.[8] This relationship has not, however, been supported by most phylogenetic work concerning Bovini.[4][7][9]

Extant

There are currently two recognized extant genera of bubalinans – the African Syncerus and the Asiatic Bubalus.[1][5][9][2] Whilst the majority of molecular and morphological work strongly supports the recognition of these two genera as being sister taxa,[5][10] since 2011 new uncertainty over the number of species that should be recognized has been introduced.[9][2] In the 'traditional' classification given by Peter Grubb in the 2005 third edition of the widely used taxonomic reference work Mammal Species of the World the following six species are recognized,[11] with the African buffalo split into five subspecies[12] based on differences in the horns and skin colouration.[9]

In 2011 Groves and Grubb recognised four of the subspecies of the African buffalo as independent species. These they argued, should be considered as separate species based on the phylogenetic species concept, which states that any population can be recognised as a species if a member is diagnosable as belonging to that population.[9] The African buffalo is noted to exhibit extreme morphological variability, and in the past a number of discreet species or subspecies have been named for specific geographic populations.[13] The bovid biologist Castelló adopted the Groves and Grubb taxonomic interpretation,[2] but others have expressed their concern that this taxonomic proposal needs more additional evidence before being adopted.[14]

Below is the listing of 'new' species recognized by Groves and Grubb (2011)[9] with vernacular names following Castelló (2016) from Bovids of the World:[2] Note other vernacular names have been used by others, and in practice all taxa are simply known as "Cape buffalo".

  • Syncerus nanus (Boddaert, 1785) – Forest buffalo
  • Syncerus brachyceros (Gray, 1837) – Lake Chad buffalo
  • Syncerus mathewsi (Lydekker, 1904) – Virunga buffalo
  • Syncerus caffer (Sparrman, 1779) – Cape buffalo

In fossil record

The fossil record of buffalos is extensive, with fossils found throughout Africa and Eurasia.[3] According to the fossil record and the molecular work, Bubalina and Bovina diverged from one and another from a common ancestor around 13.7 million years ago in the Late Miocene.[1][3][4] The Syncerus lineage and the Bubalus lineage diverged from each other in the Late Miocene, perhaps give or take between 8.2 and 9.1 million years ago.[1][3][4] This divergence corresponds to the time when the ancestor of Syncerus had arrived into Africa from Asia.[3][15]
