a. Occurring in tropical areas on all the major continents, i.e. in Africa, Asia and America, in 'all' the tropical regions. Used in biology, pertaining to area of geographical occurrence.

adj. distributed throughout the tropics [syn: pantropic]

In biogeography, a pantropical ("across the tropics") distribution is one which covers tropical regions of all continents. Examples include the plant genera Acacia and Bacopa.

Neotropical is a zoogeographic term that covers a large part of the Americas, roughly from Mexico and the Caribbean, and southwards (including cold regions in southernmost South America).

Palaeotropical refers to geographical occurrence. For a distribution to be palaeotropical a taxon must occur in tropical regions on continents in the Old World.
