"C. m. schoutedeni Schwarz, 1928 - E DR Congo, typically on Idjwi and Shushu islands in Lake Kivu; on the mainland, specimens are from the W Virunga Volcanoes and as far SW as Bobandana, although these strongly tend toward the subspecies stuhlmanni."
"In "Schouteden's Blue Monkey" (C. m. schoutedeni), pelage is long and thick, distinguished from "Stuhlmann's Blue Monkey" (C. m. stuhlmanni) by its pale gray-olive color; crown, nape, and terminal half of tail are black; and it has a white speckled frontal band."
"Recent surveys of Schouteden's Blue Monkey on the two islands where it is native have indicated that very little natural forest remains and deforestation was ongoing. No primate sightings were reported during those surveys. If Schouteden's Blue Monkey does survive on these islands, it is likely that its numbers are very low; the status of the mainland subpopulation is questionable because it is unclear that one ever existed there."

"Listed as Critically Endangered as recent (2003-2004) surveys on the two islands from whence the subspecies is known indicate that very little is left of the natural forest and there were no recorded sightings of any primates. Deforestation of the remnant forests on the islands continues, and if this primate taxon survives it is unlikely that numbers exceed a few tens of individuals. The status of the mainland subpopulation is questionable as it is not clear that it exists (or ever existed) on the mainland." Source:Hart, J. (2008). Cercopithecus mitis ssp. schoutedeni.

Was there not already a thread for this subspecies?

Was there not already a thread for this subspecies? No, could not find it. But is has been mentioned in some general threads. I've now created for the mammals (recent extinctions only) a list in excel, where I also have checked if we have a thread of that (sub)species here. This way I can check if a thread was here before or not for future reference (too many to remember all). I'm now updating the mammal sections and pages on my website and when online, I will post that excel file here as well. The other animal groups will follow as well (but much later).  |

That's excellent, Peter. I have also started to add a field in my database where I link to the TSE forum thread for each species in every taxonomic category so that that will also be helpful when determining what threads have disappeared over the entire forum (when it's completed....much later). |

Here is a very interesting video documenting the attempts to restore a viable population of this subspecies on Idjwi. It seems that in March 2015 some remnant populations was discovered around Bulolero village and the local community have now agreed to help save these populations  |

Dr. Augustin K. Basabose Laboratoire de Primatologie, Centre de Recherche en Sciences Naturelles, RD Congo Potential suitable field station for long-term primate research and conservation activities on Idjwi Island, Eastern Democratic Republic of Congo The Democratic Republic of Congo (DRC) is the first inland African country with the most non-human primate species, counting more than sixty-five different known taxa. It is the forth richest country worldwide in non-human primate species diversity behind Brazil, Madagascar and Indonesia. Despite its well acknowledged richness in primate species, the country has a very limited number of professional Congolese primatologists. Likewise, there is no country-based professional institution solely dedicated to primate research and conservation. In an attempt to fill this gap, we established the Primate Expertise (PEx), a country based organization dedicated to primate research and conservation. Primate Expertise aims to inspire young generation of Congolese primatologists to take the leadership in research and conservation to ensure long-term survival of the rich primate biodiversity of the Democratic Republic of Congo. To achieve this ultimate goal, PEx has recently carried out a scope survey on Idjwi Island to identify a suitable field station including an emblematic key primate species and establish long-term research and conservation activities. Located in Lake Kivu, Eastern of the Democratic Republic of Congo, Idjwi is the second largest island (310 sq. km) of the inland African continent. It is home to several endemic species, including the endangered blue monkey subspecies ( Cercopithesus mitis schoutedeni). Population of blue monkey inhabiting Idjwi Island (known to belong to Schoutedeni subspecies) may have separated from other Cercopithecus mitis groups of the mainland around 20,000 years ago during the formation of Lake Kivu and has therefore evolved separately on this island. Due to the large scale deforestation happening on Idjwi Island, it was once believed that this endemic subspecies was possibly extinct (John Hart, 2008). During my last trip at Idjwi, I observed a small population of blue monkey (c.a. 50 individuals) living in a tiny forest fragment. There is still a number of such small remnant fragmented forests on the Island where presence of blue monkey has been confirmed. Effort should be made to restore a viable population of Cercopithecus mitis schoutedeni on the island. To achieve this, there is a need to analyse ongoing threats to the long-term survival of Cercopithecus mitis schoutedeni and develop recommendations to halt all activities that negatively impact the primate population. This has to be done in collaboration with the local community. Through a participatory stakeholders’ consultation, PEx facilitated to establish a local-based conservation initiative willing to support primate research and conservation programs at Idjwi Island.

Seems not to be recognised as a valid subspecies by the IUCN RedList any more. It is still listed as valid under the Cercopithecus mitis assessment but it no longer has it's own subspecific assessment: www.iucnredlist.org/details/4221/0 |
