High Quality Content by WIKIPEDIA articles! Slow lorises are a group of five species of strepsirrhine primates which make up the genus Nycticebus. Found in South and Southeast Asia, they range from Northeast India in the west to the Philippines in the east, and from the Yunnan province in China in the north to the island of Java in the south. Although many previous classifications recognized fewer species, five are now considered valid: the Sunda slow loris (N. coucang), Bengal slow loris (N. bengalensis), pygmy slow loris (N. pygmaeus), Javan slow loris (N. javanicus), and Bornean slow loris (N. menagensis). The group`s closest relatives are other lorisids, such as slender lorises, pottos, false pottos, and angwantibos. They are also closely related to the remaining lorisiforms (the various types of galago), as well as the lemurs of Madagascar. Their evolutionary history is uncertain since their fossil record is patchy and molecular clock studies have given inconsistent results.
