The short ears measure in length, are pale gray at the inner surface, and black at the top. A whitish band runs from the base of the ear to the

, including an arch over the eye. It has short nasal cavities, broad at the back side. At normal unworn state, the upper incisors are Y-shaped, and become V-shaped when worn out. The hindfeet are long. ''L. c. comus'' is the largest subspecies. The total length of the skull is more than , and the height of the cheek bone is less than . The nose protrudes forward, and reaches up to the front of the upper incisor. ''L. c. pygmaeus'' is the smallest subspecies, with the narrowest frontal aspects and the longest latus. The Yunnan hare is smaller than the woolly hare; the supraorbitals are flat and small, and the toothrow and

(space between two teeth) are of different proportions. It also has a characteristic brighter pelage than the woolly hare, although, according to Gao Yaoting, the Yunnan hare's gray rump is also a characteristic of the woolly hare.

Behavior and ecology

s. According to reports by hunters, the adult Yunnan hare has three burrows; those of the male are shallower, smaller, and straighter than those of the female that are oval and larger in shape. Breeding usually commences in April. There are one to four, usually two, young in a litter, and in May, the female gives two or three litters.


Status and conservation

Since 1996, the Yunnan hare is rated as a species of 
least concern A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. T ...

. This is because it is a widespread species, and it has been reported by residents to be commonly found. Although the current state of its population trend is unclear, the Yunnan hare population is likely to be secure as it occurs in remote areas in southwestern China. However, agricultural activities on mountainous regions may pose a threat to the species by isolating its mountain populations. The Red List of China's Vertebrates has listed the Yunnan hare as near threatened, nearly meeting the criteria to be listed as vulnerable. It occurs in protected areas and also in the Changshanerhai, Daweishan, Gaoligongshan, Jinpingfenshuiling, Nujiang, Shilin, and Tongbiguan Nature Reserves.
