Pantala flavescens, [3] the globe skimmer, globe wanderer or wandering glider, [1] is a wide-ranging dragonfly of the family Libellulidae. [1] This species and Pantala hymenaea, the "spot-winged glider", are the only members of the genus Pantala. It was first described by Johan Christian Fabricius in 1798. [4]

Pantala hymenaea (spot-winged glider) [1] is a dragonfly of the family Libellulidae. It is a migratory species and is native to North, Central and South America, travelling widely and breeding in temporary water bodies. It looks very similar to the wandering glider, with the addition of a dark basal spot on the hindwing.
The Dragon's Tail is a modern name for the phantom peninsula in southeast Asia which appeared in medieval Arabian and Renaissance European world maps. It formed the eastern shore of the Great Gulf (Gulf of Thailand) east of the Golden Chersonese (Malay Peninsula), replacing the "unknown lands" which Ptolemy and others had thought surrounded the "Indian Sea".
In medieval T and O maps, Asia makes for half the world's landmass, with Africa and Europe accounting for a quarter each. With the High Middle Ages, Southwest and Central Asia receive better resolution in Muslim geography, and the 11th century map by Mahmud al-Kashgari is the first world map drawn from a Central Asian point of view.
These varying definitions are not generally reflected in the map of Asia as a whole; for example, Egypt is typically included in the Middle East, but not in Asia, even though the bulk of the Middle East is in Asia. The demarcation between Asia and Africa is the Suez Canal, the Gulf of Suez, the Red Sea, and the Bab-el-Mandeb.
The four continents, plus Australia, added later.. Europeans in the 16th century divided the world into four continents: Africa, America, Asia, and Europe. [1] Each of the four continents was seen to represent its quadrant of the world—Africa in the south, America in the west, Asia in the east, and Europe in the north.
The name Africa was originally used by the ancient Romans to refer to the northern part of the continent that corresponds to modern-day Tunisia. There are many theories regarding its origin. Africa terra means "land of the Afri" (plural, or "Afer" singular), referring to the Afri tribe, who dwelt in Northern Africa around the area of Carthage.
