Saigini je tribus parnoprstaških sisavaca potporodice Bovinae. Ovaj tribus čine dvije vrste gazela srednjih veličina koje nastanjuju Euroazijsku stepu.

Taksonomija

Opis

Tribus je 1945. godine stovrio američki paleontolog i teoretičarski biolog George Gaylord Simpson.^[1] Prema Simpsonu tribus se sastoji od dva monotipičnih rodova:

Tribus Saigini
- Rod Pantholops
  - Pantholops hodgsonii
- Rod Saiga
  - Saiga tatarica

Kontrovezna taksonomija

Saiga i Pantholops su problematični taksonomijskih rodovi.^[2] Saiga je bila tradicionalno klasificirano kao rod potporodice Caprinae,^[2]^[3] no neki autori sugeriraju da je rod Saiga bliži potporodici Antilopinae.^[4] Godine 2000. Groves je analizirao morfološke karakteristike rodova Procapra, Prodorcas i Saiga i predložio tri bazalne skupine Antilopiae, od kojih je jedna uključivala kladu Saiga + Procapra.^[5]

Rod Panthalops je monotipilan (P. hodgsonii) te je pponekad uključen u tribus Saigini na temelju sličnih morfoloških obilježja od kojih je većina plesiomorfna. Međutim, molekularni i morfološki nalazi sugeriraju da je ispravnije svrstati Pantholops hodgsonii u potporodicu Caprinae,^[4]^[6] no status tibetanske gazele u ovoj potporodici ostaje neizvjesan. Podatci o citokromu b i malim proporcijama v i 16S rDNA sugestiraju filogenetske afinitete Saiga i Procapra s Antilopinae.^[4]^[7]^[8] Međutim, ove studije ne pojašnjavaju bliske odnose unutar ove klade. S obzirom na ovu nesigurnost, neki autori su predložili odbacivanje taksona Saigini.^[8]
