The most evident morphological features at skull construction are also be noticed the size and shape of incisive foramina. In contrast with +M. s. finis +, which usually has shorter, reniform openings with clearly pointed cranial edge of notch, +M. s. tonkinensis +has more elongated foramina with more or less rounded cranial and caudal edges of notch figures 7-9, its somewhat reassemble in shape to the foramina characteristic to representatives of genus + +Leopoldamys + +but much wider at caudal side. The most remarkable external feature is the pattern of tail coloration, namely the character of tail tip discoloration. This progressive discoloration, characteristic for all + +M. surifer + +starts appreciably earlier than it usually happens with representatives of southern populations, discolorations starts page 16 of 19 + + +approximately from the middle of tail and terminal one third usually became completely white, whereas for +M. s. finis +discolorations launched from approximately terminal third with only very tip about 1/5 of tail length being completely discolored. + + +Distribution +: Northern +Vietnam +from +Ha Tinh Province +in its extreme south to Ba Vi ( +Hanoi +area) in the north; central +Laos +( +Khammouane +and +Bolikhamxai +provinces). It may be probably found in southernmost +Yunnan +, +China +( +Wang 2003 +) and northern +Laos +, but its presence there has to be approved by investigation of museum specimens or new field records. + + +Acknowledgment: +This work and the one new subspecies name have been registered with Zoo Bank under + +urn:lsid:zoobank.org:pub: +017C3A9D- 9B40-4C8C-A621-7BF5883DD1D7 + +.

In the present study, we examined cleared and stained specimens of + +A +. +mangois + +, + +A +. +arunachalensis + +, + +A +. +apangi + +, and + +A +. +waikhomi + +and found the pinnate like rays (except + +A +. +apangi + +) only on the distal half of the anterior margin of the segmented procurrent rays and unbranched principal rays. Ng and Kottelat [ +9 +] further reported the presence of pinnate like rays along the median caudal-fin rays of + +Amblyceps + +of the Indian subcontinent. This finding was confirmed by our observations on + +A +. +mangois + +( +Fig 4a; S +3 +Fig) and + +A +. +arunachalensis + +( +Fig 4b +), which exhibited strongly-developed ossified projections on the proximal lepidotrichia of the median caudal-fin rays.
