- Biswamoyopterus gaoligongensis
Diagnosis. Biswamoyopterus gaoligongensis sp. nov. can be distinguished from the other two described species of Biswamoyopterus by the following combination of traits: 1) The ear tufts at the base of the posterior margins of ears are bicolored, basally white and terminal black. The scrotum is dark brown which strongly contrasts with the yellowish-white abdominal pelage. 2) The muzzle is very short, and the zygomatic arch is distinctly expanding outward, making the outline of the skull short and wide. The outer margin of the nasal bone, the orbital margin of the frontal bone, and the post-orbital margin of the frontal bone are almost parallel to the midline of skull on the dorsal view. The central point of the posterior margin of the palatal bones lies in front of the posterior margin of M 3. 3) M 1 and M 2 are sub-square in outline, and as large as P 4. The hypoconid of P 4 - M 2 are very developed, strongly pointed towards posterior buccal side.
Etymology. The specific name is derived from Mount Gaoligong, the type locality of the new species and - ensis, Latin for belonging to.
