My friend found it and I made it into a specimen.
There are three black stripes on the back, five golden stripes, and the golden stripes are continuous with the stripes under the eyes, so I judge it is Tamiops mcclellandii. It has white hair behind its ears and a yellow-brown abdomen. The tail is layered in color from top to bottom, with yellow belly surface and gray with silvery white hair tips on the back.
