Species: Presbytis hosei canicrus
Common Name: Miller’s grizzled langur
Presbytis hosei canicrus is a subspecies of grey leaf monkey. It was feared to be extinct but has recently been observed in Borneo. Picture Source
Species: Parapapio broomi
The genus Parapaio is composed of four species: Parapapio jonesi, Parapapio whitei, Parapapio broomi, and Parapapio antiquus. The picture of Parapapio broomi below is that of a specimen from Bolt’s Farm and dates to about 2 MYA (the picture is somewhat distorted the snout is not as long as in a but is longer than in b. I have been unable to correct the distortion but the original picture can be found here). Parapapio broomi has also been found at Sterkfontein.
Species: Pongo abelii
Common Name: Sumatran Orangutan
The sumatran orang lives, obviously, in Sumatra – they are an endemic species. According several genetic analysis the Sumatran and Bornean populations diverged from each other about 1.5-1.7 MYA. They are largely frugivorous and spend most of their time in trees. On the ground they are quadrupedal. Unlike the chimpanzee, bonobo, and gorilla, they are not knuckle walkers they use their fist. Males tend to be solitary.
Species Lophocebus aterrimus
Common Name: Black Mangabey, Black-crested Mangabey
Species: Rhinopithecus roxellana
Common: Golden snub-nosed monkey
The taxonomy of the snub-nosed langurs is somewhat muddled. For purposes of this post I am following the simplest arrangement. The genus Rhinopithecus contains four species, three of which live at high elevations (up to about 4,500 meters) in China and the Tibetan plateau.
Species: Papio hamadryas
Normally, in these posts I try to provide some basic information about the species I’ve picked and provide a few pictures. In this post I would like to do something a little different.
Know Your Primate grew out of posts I wrote specifically for the Friday Ark back on my old blog. The point was to write short, informative posts about whatever species struck my fancy (and at that point was not limited to primates). Once I moved to ScienceBlogs those kind of posts went by the wayside. Then in July, 2006 I decided to resurrect the idea with a specific focus on primates. In the time since I have focused on a wide variety of primates but, with one or two exceptions, have avoided the extant apes. This is largely due to the explosion of knowledge about them in the past 10-15 years, which makes it hard to write a short post in the format I have chosen for this series. Bearing that limitation in mind, here is this weeks primate.
