Dwarf Tree Mouse
French: Loirpygmée du Jiaozi / German: Zwergbilch / Spanish: Raton arboricola enano
Taxonomy. Typhlomys nanus Cheng Feng et al., 2017 ,
“ Mt. Jiaozi (26° 08’ N, 102° 85’ E), Wumeng township, Luquan County, Kunming, Yunnan, China; elevation approximately 3,252 m asl.”
This species is monotypic.
Distribution. Known only from Mt Jiaozi and Mt Dawei in Yunnan (SW China). View Figure
Descriptive notes. Head—body 65-74 mm, tail 97-106 mm; weight 8-8-13-2 g. The Dwarf Tree Mouse is the smallest species of Typhlomys . Pelage is distinctly bicolored, with ash-gray dorsum and creamy white venter and cheeks; ears are large and naked; eyes are small; whiskers are long; long tail is lightly furred near base but densely furred at tip (resembling a bottle brush); and hair at tip oftail is white in some individuals. Braincase is dome-shaped.
Habitat. Only known from secondary forests on two mountains at elevations of 2000-3000 m. Forests had acidic, red soil and were composed mostly of George's fir ( Abies forvestii var. georgei , Pinaceae ) with undergrowth of bamboo and rhododendron ( Rhododendron , Ericaceae ).
Food and Feeding. The Dwarf Tree Mouse is probably granivorous and frugivorous.
Breeding. No information.
Activity patterns. The Dwarf Tree Mouse is probably nocturnal as are other forestdwelling rodents.
Movements, Home range and Social organization. Given its close evolutionary relationship with the Chapa Tree Mouse (7. chapensis ) and similar morphologies (including exceptionally small eyes), it is possible that the Dwarf Tree Mouse also uses ultrasonic echolocation for navigation.
Status and Conservation. Not assessed on The [UCN Red List.
