CITES Appendix II. Classified as Near Threatened on The IUCN Red List (as P. melalophos melalophos). The Black-crested Sumatran Langur is protected by Indonesian law. There has been widespread recent loss of habitat in its distribution, mainly for oil palm plantations. Nevertheless, it is still relatively common, and it seems thatit can tolerate some degree of land conversion and forest degradation. Populations are now, however, very fragmented. It is commonly trapped for the illegal pet trade, but less so than the Mitered Langur (P. mitrata). This and some incidental hunting for food are threats acrossits range. It occurs in Kerinci-Seblat National Park and Bukit Sebelah Protection Forest in Sumatra. The still rather confused taxonomy, confounded by different color variants and little understood boundaries of the ranges of this and other species (formerly considered subspecies), requires further research to better understand the conservation status of the Black-crested Sumatran Langur.","source":"Cercopithecidae","sourceTaxonKey":197824759},{"key":447439230,"taxonKey":5219561,"type":"description","language":"eng","description":"Descriptive notes.

The Black-crested Sumatran Languris variable in its pelage and coloration. It is so-named for the distinctive, blackpointed crest on its crown. Coat color ranges from white through gray to reddishorange. Tail is normally bi-colored (dark above and white below). The Black-crested Sumatran Langur is generally reddish-orange above (tipped with black), with a white, yellow, or pale orange underside. Outersides of limbs tend to be paler (more orange), and inner sides of limbs white, with hands and feet usually orange but sometimes black. Tail is like the body above and whitish underneath for the proximal half. Facial skin is black, and cheeks are straw-colored and separated from the whitish forehead by a reddish or blackish band. Crown crest is black, and there is usually a single, indistinct whorl on forehead (none or two in some populations), as well as a U-shaped parting on nape.","source":"Cercopithecidae","sourceTaxonKey":197824759},{"key":447439231,"taxonKey":5219561,"type":"discussion","language":"eng","description":"Formerly, P. mitrata, P. bicolor, and P. sumatrana were considered subspecies of P. melalophos. There are widespread geographic gradients in color and individual variation (often in the form of wellmarked morphs), making assignment of subspecies difficult. In addition to the typical P. melalophos, there are three main morphs that coexist widely overits distribution. They have been described as “ nobilis ” (foxy-red), “ ferruginea’ (less reddish), and “ aurata’ (golden-buff with a black spot on chest, black hands and feet, and a white tail-tip). There is a fourth form described by N. F. Chasen in 1940 with the name fluviatilis. It is found in Palembang, Sumatra, and is similar to the Black-crested Sumatran Langur but much paler. The taxonomic status of these morphsis currently under study. According to genetic and acoustic data, the proposed distribution of P. melalophos may have to be extended into the distribution of P. mitrata. Monotypic.","source":"Cercopithecidae","sourceTaxonKey":197824759}]}
