Information:  - Antlers are extensions of the skull grown by members of the deer family. They are not true bone structures but they usually grow in symmetrical pairs. In most species, only the male grows antlers and the antlers primarily function in sexual selection as attractions to females and as weapons in fights for control of harems. In many temperate zone species, antlers are shed and regrow each year, while horns are permanent.  - Deer (singular and plural) are the ruminant mammals forming the family Cervidae. The two main groups are the Cervinae, including the muntjac, the fallow deer and the chital, and the Capreolinae, including the elk, reindeer (caribou), the Western roe deer, and the Eurasian elk (moose). Female reindeer, and male deer of all species (except the Chinese water deer), grow and shed new antlers each year. In this they differ from permanently horned antelope, which are in the same order, Artiodactyla.  - The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer. Alternatively, they are known as the telemetacarpal deer, due to their bone structure being different from the plesiometacarpal deer subfamily Cervinae. The telemetacarpal deer maintain their distal lateral metacarpals, while the plesiometacarpal deer maintain only their proximal lateral metacarpals.  The Capreolinae are believed to have originated in the Late Miocene, between 7.7 and 11.5 million years ago, in central Asia.  - The chital or cheetal ("Axis axis"), also known as spotted deer or axis deer, is a deer found in the Indian subcontinent. The species was first described by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach nearly and females at the shoulder. While males weigh , the lighter females weigh . The species is sexually dimorphic: males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears and tail are all white. The antlers, three-pronged, are nearly long.  - The European roe deer ("Capreolus capreolus"), also known as the western roe deer, "chevreuil", or simply roe deer, is an Eurasian species of deer. The male of the species is sometimes referred to as a roebuck. The roe deer is relatively small, reddish and grey-brown, and well-adapted to cold environments. The species is widespread in Europe, from the Mediterranean to Scandinavia and from Britain to the Caucasus. It is distinct from the somewhat larger Siberian roe deer.  - Cephenemyiini is a tribe within the family Oestridae which includes large flies , parasitic on deer and related ungulates . Tribe Cephenemyiini Genus Cephenemyia Latreille , 1818 C. apicata Bennett and Sabrosky , 1962 C. auribarbis ( Meigen , 1824 ) C. grandis C. jellisoni Townsend , 1941 C. kaplanovi C. macrostis Brauer , 1863 C. phobifer ( Clark , 1815 ) C. pratti ( Clark , 1815 ) C. stimulator Hunter , 1916 C. trompe ( Modeer , 1786 ) C. ulrichii Brauer , 1863 Genus Pharyngomyia Schiner , 1861 P. picta ( Meigen , 1824 )  - Muntjacs, also known as barking deer and Mastreani deer, are small deer of the genus "Muntiacus". Muntjacs are the oldest known deer, thought to have begun appearing 1535 million years ago, with remains found in Miocene deposits in France, Germany and Poland.  - The elk, or wapiti ("Cervus canadensis"), is one of the largest species within the deer family, Cervidae, in the world, and one of the largest land mammals in North America and Eastern Asia. This animal should not be confused with the still larger moose ("Alces alces") to which the name "elk" applies in British English and in reference to populations in Eurasia. Apart from the moose, the only other member of the deer family to rival the elk in size is the south Asian sambar ("Rusa unicolor").  - The water deer ("Hydropotes inermis") is a small deer superficially more similar to a musk deer than a true deer. Native to China and Korea, there are two subspecies: the Chinese water deer ("Hydropotes inermis inermis") and the Korean water deer ("Hydropotes inermis argyropus"). Despite its lack of antlers and certain other anatomical anomaliesincluding a pair of prominent tusks (downward-pointing canine teeth), it is classified as a cervid. Its unique anatomical characteristics have caused it to be classified in its own genus (Hydropotes) as well as its own subfamily (Hydropotinae). However, a study of mitochondrial cytochrome b sequences placed it near "Capreolus" within an Old World section of the subfamily Capreolinae. Its prominent tusks (elongated canines), similar to those of musk deer, have led to both being colloquially named vampire deer in English-speaking areas to which they have been imported. The species is listed as Vulnerable by the IUCN.  - Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria.  - Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data.  - The reindeer ("Rangifer tarandus"), also known as caribou in North America, is a species of deer with circumpolar distribution, native to Arctic, Subarctic, tundra, boreal and mountainous regions of northern Europe, Siberia, and North America. This includes both sedentary and migratory populations.  - The fallow deer ("Dama dama") is a ruminant mammal belonging to the family Cervidae. This common species is native to western Eurasia, but has been introduced to Antigua & Barbuda, Argentina, South Africa, Fernando Pó, São Tomé, Madagascar, Mauritius, Mayotte, Réunion, Seychelles, Comoro Islands, Morocco, Algeria, Tunisia, Cyprus, Israel, Cape Verde, Lebanon, Australia, New Zealand, Canada, the United States, the Falkland Islands and Peru. Some taxonomers include the rarer Persian fallow deer as a subspecies ("D. d. mesopotamica"), while others treat it as an entirely different species ("D. mesopotamica").  - The Cervinae or the Old World deer (denoting their place of origin, not their current distribution), are a subfamily of deer. Alternatively, they are known as the plesiometacarpal deer, due to their ankle structure being different from the telemetecarpal deer of the Capreolinae.  - An antelope is a member of a number of even-toed ungulate species indigenous to various regions in Africa and Eurasia. Antelopes comprise a wastebasket taxon (miscellaneous group) within the family Bovidae, encompassing those Old World species that are not cattle, sheep, buffalo, bison, or goats. A group of antelope is called a herd.    After reading the paragraphs above, we are interested in knowing the entity with which 'cephenemyiini' exhibits the relationship of 'taxon rank'.
