Question: What was the other name for the extinct tiger subspecies, which inhabited the sparse forests and riverine corridors west and south of the Caspian Sea, from Turkey, Mesopotamia, Iran and the Caucasus, that has a project reestablishing populations of the Siberian tiger by introducing them as replacements to the extinct tiger? 

full_context: Document 1: Wanhsien tiger: The Wanhsien tiger ("Panthera tigris acutidens"), is an extinct subspecies of tiger that lived in Asia from the late Pliocene until the middle Pleistocene. They were driven to extinction in the islands of Indonesia by another tiger subspecies, the Trinil tiger ("P. t. trinilensis") and in Asia by yet another subspecies, the South China tiger ("P. t. amoyensis")
Document 2: Bengal tiger: The Bengal tiger ("Panthera tigris tigris") is the most numerous of the tiger subspecies. By 2011, the total population was estimated at fewer than 2,500 individuals with a decreasing trend. None of the Tiger Conservation Landscapes within the Bengal tiger's range is considered large enough to support an effective population size of 250 adult individuals. Since 2010, it is listed as Endangered on the IUCN Red List. An example of charismatic megafauna, the Bengal tiger is the most familiar tiger subspecies, as well as the second largest
Document 3: Caspian red deer: The Caspian red deer ("Cervus elaphus maral"), is one of the easternmost subspecies of red deer that is native to areas between the Black Sea and Caspian Sea such as Crimea, Asia Minor, the Caucasus Mountains region bordering Europe and Asia, and along the Caspian Sea region in Iran. The Caspian red deer is sometimes referred to as maral, noble deer, or eastern red deer.
Document 4: Zov Tigra National Park: Zov Tigra National Park (Russian: Зов Тигра национальный парк)), (in English, "Call of the Tiger National Park", or "Roar of the Tiger") is a mountainous refuge for the endangered Amur Tiger. The park encompasses an area of 83384 ha on the southeast coast of Russia's Far East in the federal district Primorsky Krai (in English, "Maritime Region"). The park is about 100 km northeast of Vladivostok, on both the eastern and western slopes of the southern Sikhote-Alin mountain range, a range that runs north-south through the Primorsky Krai. The relatively warm waters of the Sea of Japan are to the east, the Korean peninsula to the south, and China to the West. The terrain in rugged and difficult to access, with heavily forested taiga coexisting with tropical species of animals and birds. The park is relatively isolated from human development, and functions as a conservation reserve. Tourists may visit the portions of the park marked for recreation, but entry to the protected zones is only possible in the company of park rangers.
Document 5: Siberian Tiger Introduction Project: The Siberian Tiger Introduction Project involves reestablishing populations of the Siberian tiger ("Panthera tigris altaica)", also known as the Amur tiger, in their former range and also expanding their range by introducing them as replacements of their genetically similar relative, the extinct Caspian tiger ("Panthera tigris virgata") which inhabited Central and Western Asia. Currently, the Siberian tiger inhabits the cold mountains of the Russian Far East and northern China.
Document 6: Bali tiger: The Bali tiger ("Panthera tigris balica") is an extinct tiger subspecies that lived in the Indonesian island of Bali.
Document 7: Sable: The sable ("Martes zibellina") is a marten species, a small carnivorous mammal inhabiting forest environments, primarily in Russia from the Ural Mountains throughout Siberia, northern Mongolia. Its habitat also leans the borders of eastern Kazakhstan, China, North and South Korea and Hokkaidō in Japan. Its range in the wild originally extended through European Russia to Poland and Scandinavia. It has historically been hunted for its highly valued dark brown or black fur, which remains a luxury good to this day. While hunting of wild animals is still common in Russia, most fur in the market is now commercially farmed.
Document 8: South China tiger: The South China tiger ("Panthera tigris amoyensis") is a tiger subspecies in the provinces of Fujian, Guangdong, Hunan, Jiangxi in southern China. It has been listed as Critically Endangered on the IUCN Red List since 1996, and is possibly extinct in the wild since no wild individual has been recorded since the early 1970s. Already in the late 1990s, continued survival was considered unlikely due to low prey density, widespread habitat degradation and fragmentation, and other human pressures. The name "Amoy tiger" was used in the fur trade. It is also known as the "South Chinese", the "Chinese", and the "Xiamen" tiger.
Document 9: Wildlife of Iraq: The wildlife of Iraq includes its flora and fauna and their natural habitats. By the early twentieth century, Iraq had lost all of its megafauna, except for the Syrian brown bear. Prior to the introduction of gunpowder, Iraq was inhabited by many iconic animals such as the Mesopotamian lion, Caspian tiger, and Asiatic cheetah. Iraq has multiple biomes which include the mountainous Kurdistan region in northern Iraq to the wet marshlands along the Euphrates river and the west part of the country comprises desert and some semi-arid regions. As of 2001, seven of Iraq's mammal species and 12 of its bird species are endangered. The endangered species include the northern bald ibis and Persian fallow deer. The Syrian wild ass is extinct, and the Saudi Arabian dorcas gazelle was declared extinct in 2008.
Document 10: Temperate rainforests of the Russian Far East: The temperate rainforests of the Russian Far East are found within the Russian states of Primorsky Krai and Khabarovski Krai and contains the Sikhote-Alin mountain range. Found within the Russian Federation, this area is one of the most productive and diverse forests in the world and also contains one of the highest endangered species densities on Earth. While most temperate rainforests around the world have retained only a fraction of their historical range, these forests maintain the majority of their former range and almost all of their historical biodiversity. The region is also notable for having what has become the last remaining large tract of viable habitat for the critically endangered Amur tiger and Amur leopard.
Document 11: Indochinese tiger: The Indochinese tiger ("Panthera tigris corbetti") (Thai: เสือ โคร่ง อิน โด จีน , "S̄eụ̄x khor̀ng xin do cīn") (Vietnamese: "Hổ Đông Dương" ) is a tiger subspecies that lives in Myanmar, Thailand, Lao PDR, Viet Nam, Cambodia, and southwestern China. It has been listed as Endangered on the IUCN Red List since 2008, as the population seriously declined and approaches the threshold for Critically Endangered. As per 2011, the population was thought to comprise 342 individuals. The largest population unit survives in Thailand estimated at 189 to 252 individuals. There are 85 individuals in Myanmar, and only 20 Indochinese tigers remain in Viet Nam. It is considered extinct in Cambodia.
Document 12: Siberian tiger: The Siberian tiger ("Panthera tigris altaica"), also called Amur tiger, is a tiger subspecies inhabiting mainly the Sikhote Alin mountain region with a small population in southwest Primorye Province in the Russian Far East. The Siberian tiger once ranged throughout all of Korea, north-eastern China, Russian Far East, and eastern Mongolia. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs. This was followed up by a more detailed census which revealed there was a total population of 562 wild Siberian tigers in Russia.
Document 13: Caspian tiger: The Caspian tiger ("Panthera tigris virgata") is an extinct tiger subspecies, which inhabited the sparse forests and riverine corridors west and south of the Caspian Sea, from Turkey, Mesopotamia, Iran and the Caucasus, through Central Asia to the Takla Makan desert of Xinjiang in China, until the end of the 20th century. Depending on the region, it was also called Hyrcanian tiger, Turanian tiger, Persian tiger, and "Babre Mazandaran" (Persian: ‎ ‎ , Tiger of Mazandaran). It was one of the largest big cats to have ever lived and was described as being intermediate in size between Siberian and Bengal tigers.
Document 14: Asiatic cheetah: The Asiatic cheetah ("Acinonyx jubatus venaticus"), also known as Iranian cheetah is a Critically Endangered cheetah subspecies surviving today only in Iran.
Document 15: Panthera tigris sudanensis: The Panthera tigris sudanensis is a claimed subspecies of tiger, not scientifically recognised, allegedly living in Africa. It was described in 1951 by Paul E. P. Deraniyagala, based on a fur he saw in a Cairo bazaar. When he asked the seller for information, Deraniyagala was told the animal was shot in the Sudan. As Mazák wrote in 1980, it was either a joke or the seller felt obliged to be polite and answer any question, whether with truth or an invention. Deraniyagala took a picture of the specimen's fur, which, when published, made the scientists say, according to the pattern of stripes, it was most likely a fur of the Caspian tiger ("Panthera tigris virgata") and the fur must have been smuggled from Iran or Turkey. At that time, the Caspian tiger was nearly extinct. If a photo were enough for a scientific description, "Panthera tigris sudanensis" would now be one of the Caspian tiger's synonyms; as Mazák wrote, "the situation is half-humorous, half-ironic." Tigers are not known to have ever inhabited Africa.
