Western Lowland Olingo

The western lowland olingo (Bassaricyon medius) is a species of olingo from Central and South America, known from Panama and from Colombia and Ecuador west of the Andes. It is smaller than the northern olingo but larger than the olinguito of the cloud forest. It has a head and body length of 31 to 41 centimetres and a tail of 35 to 52 centimetres, weighs about 0.9 to 1.2 kilograms and has slightly lighter fur than its eastern relative. Two subspecies are recognised, the nominate Bassaricyon medius medius in Colombia and Ecuador, and B. m. orinomus in Panama and possibly Colombia, which is about the size of the eastern lowland olingo. Its closest relative is the eastern lowland olingo, from which it diverged about 1.3 million years ago.
