The Chapa pygmy dormouse or Vietnamese pygmy dormouse (Typhlomys cinereus chapensis) is a rodent endemic to Vietnam; this nocturnal creature is 7-10cm long (3-4 inches), with a tail of 10-13cm (4-5 inches) and long ears. ^[1]

In 2014, it was mainly found to the west of the Red River, in north Vietnam and southern Yunan Province in China. ^[2]

It is often seen as a subspecies of the Chinese pygmy dormouse (T. cinereus), along with T. ci daloushanensis, T. ci. Guangxiensis and T. ci. Jingdongensis; in 2014, it was seen by Abramov et al as an individual species and separate from T. cinereus. ^[2]

At the start of the 21st century, it was listed as a critically endangered species. ^[3] By 2017, the status of the general T. cincereus was as a creature of ‘least concern’. ^[4]
