Prosimian
Prosimians are the suborder Strepsirhini, the most primitive extant primates; they represent forms that were ancestral to monkeys, apes and man.
Prosimians are the only primates native to Madagascar, and are also found in Southeast Asia. The tarsiers were once classified in the Strepsirhini, but are now grouped in suborder Haplorhini with the monkeys and apes and still called prosimians as they are the most primitive of the extant haplorhines.
Strepsirhini clade is compose of seven families split into two groups. The four families of lemurs include all of the creatures typically called lemur. The other three families include all of the lorises, plus the galagos, the Aye-aye, and the pottos.
The adapids are an extinct polyphyletic grouping that were most certainly prosimians and closely related to the strepsirhines.
