The bamboo bats are a genus of vesper bats, Tylonycteris, whose name means padded bat. It refers to the hairless, fleshy pads on the hands and feet that the bats use to grip bamboo, and the species in the genus roost within bamboo shoots (Wikipedia, general account of the bamboo bats).
The cached account is about the genus as a whole and gives nothing on the Tonkin greater bamboo bat's appearance, range, diet or breeding, so this entry is limited to what is known of the genus; checklists place the species in China, Vietnam and Laos.
