Today’s news featured a story which I wasn’t expecting at all in 2022–a new species of primate has been identified in the Mekong region! Actually the new langur was discovered in 2020 (when it was duly reported by the BBC) but the news did not make it to the World Wildlife Fund’s list of newly discovered species until now thanks to circumstances of the wider world. Indeed, the endearing Popa langur was not alone: there were 224 newly discovered species on the list released by the conservation group. The list highlights the need to protect biodiversity in the Mekong region (Cambodia, Laos, Myanmar, Thailand, Vietnam) where new species are still being discovered. Ferrebeekeeper has previously posted about the saola and iridescent snake for similar reasons (you should look at those posts since they rhapsodize about the mysterious hinterlands of Indochina, which are home to all sorts of mysterious and compelling creatures). Speaking of new snakes, this year’s WWF report also included a bright orange snake that lives on slugs!
The new langur species was identified by whiskers which point forward and by broad white circles around its clever eyes…oh and by DNA (in fact the species was originally discovered and collected in the 19th century, but nobody properly identified the bones at Britain’s Natural History Museum as belonging to a new monkey species until now). Unfortunately this “new” primate is already in pretty deep trouble and scientists estimate the total population to be at 200-300 individuals, most of whom seem to live near Myanmar’s dormant Popa Volcano (an otherworldly location pictured immediately below).

It is easy to wring our hands about the fate of these amazing new rainforest organisms, since they may well disappear forever…right after we have learned they exist. Myanmar, in particular, is going through a destructive era in the aftermath of the 2021 coup d’etat. Yet the pristine forests of Southeast Asia (along with their ghost monkeys, iridescent snakes, and giant catfish) have lasted this long thanks to their remoteness and to the customs and lifestyles of the people who live there. And the national governments are not universally dedicated to economic extraction over all else (Vietnam in particular is serious about protecting its ecological treasures–like their astonishing giant softshell turtles). The rest of us need to find a way to help out. There are wonders in the Mekong jungle (and I never even told you about the new succulent bamboo species).

Labor Day is over. Another summer is dying away. I wanted to celebrate the summer (it is my favorite season!) without giving into the elegiac feelings of fall, so I drew this sunset drawing of merriment in Central Park. As always my muse is the incomparable Lillian Newberg, doyenne of the resurrected New York roller disco scene (would that I could participate–but I can no more dance…or walk…or stand still…on roller skates than I can fly like Superman). Around her are strange & mysterious circus folk with hotdogs and ice cream, while a rather splendid toucan preens at the treeline. The sloth is not a roller skater either, but at least he can drag himself to the party on a skateboard. A langur turns the magical disco jack-in-the-box, while various angelic folk fly around the heavens as per their wont. The scene is delightful except for the tragic sentient lemon and the rubber chicken (which has been accidentally discharged from a novelty cannon). The snake represents moral choice whereas the flounder suggests that our appetites will always be lurking in the immediate foreground of anything we do. I don’t know what is up with that fancy garter belt. Somebody probably dropped it there by accident and it has nothing to do with the larger parable…

So far, Primate Week has been a huge success! The Year of the Fire Monkey has featured the loudest land animal, the immortal magician monkey god, and the disconcerting calculus of Dunbar’s number. There is still another topic which I wanted to address—an important primate post which I have planned to write for a long time–but it is almost midnight on Friday night, so I am going to bunt with a quick gallery post about color. Last week I wrote a piece about humankind’s love for the color red. I blithely assured everyone that primates are the most colorful mammals…however I didn’t back that up with any images.
Therefore, here are some beautifully colorful primates. I am only listing the species and the source (where available) so that you can revel in the beautiful color of these monkeys. If you want to learn what these colors betoken and how each species evolved such lovely patterns, you will have to look elsewhere. I have done my best to label each picture, but the WordPress function which allows a a blog’s creator to label images has been broken a long time (at least for the template I use). If you have any questions, just ask in the comments!

It is a pretty intense rainbow! Look at how expressive their faces are. It is possible to read the personality of each monkey. Some of them remind of acquaintances from secondary school or world leaders, but of course we humans are not quite so colorful. Still we can pull off a mean combination of orange pink and brown in our own right. We also change colors somewhat when we are aroused, angry, or afraid! Colorful mammals indeed!

I have been wanting to expand Ferrebeekeeper’s “mammals” categories by writing more about primates…but primates are really close cousins. They are so near to us on the tree of life that it is tricky to write about them. Monkeys and apes venture into the uncanny valley…that uneasy psychological chasm that contains things that are very much like humans, but clearly are not humans.
Therefore, in order to ease us into the subject of primatology, I am going to start with the spectacled langur aka dusky leaf monkey (or, more properly Trachypithecus obscurus). This is a beautiful langur which lives in the dense rainforests of Malaysia, Burma, and Thailand, but realtively little seems to be known about the creatures. Adult male dusky leaf monkeys weighs approximately 8.3 kilograms (18 pounds). Females are somewhat smaller. The monkeys live in troops of about ten or a dozen and they subsist on a variety of tropical fruits and nuts (supplemented perhaps occasionally with other vegetables or small animals). Infants are born orange, but quickly turn dark gray with the distinctive “spectacles” for which the species in known. I don’t really have a great deal of information about these monkeys, but I am blogging about them anyway because they are adorable! Just look at these young langurs. This is exactly the sort of cute introduction which we need to get us started on the topic of primates. We will work on the serious grim monkeys later!
