Also called Aka Dwarf Bradicebus Tardigradus, Wind Monkey and Small Loris, it belongs to the Lorisidae family of Primates order. Its Latin scientific name is Nycticebus pygmaeus, and English name is Lesser Slow Loris or pygmy loris.      

It is very similar to Bradicebus Tardigradus, but smaller than -- only half as large as Bradicebus tardigradus. It is 21 to 22.5 centimeters in body length, 1.2 centimeters in tail length, and 325 to 425 grams in weight. Its round head has round and large eyes, with white mouth, nose, and lip but no cheek pouch. The body hair is in thin eider shape, mostly orange russet. There is one deep color line leading from mid-dorsal to vertex, and the belly and four limbs are silver gray luster.

Its living environment and food habit are similar to that of Bradicebus tardigradus. Scientific records on distribution of Lesser Slow Loris in China (in 1986) showed that several Lesser Slow Loris captured from Yunnan Province were at that time considered as juveniles of Bradicebus Tardigradus, and one female among them produced a baby. Its breeding habit is probably similar to that of Bradicebus Tardigradus. It litters in February to March, and the breast-feeding period is about 210 to 252 days.

Lesser Slow Loris belongs to rare low-grade monkeyjolly, with a very narrow distribution. In China it is only found in southern Yunnan Province. Severely disturbed by human activities, it is in urgent need of protection.
