Achalinus timi sp. nov. lacks a separate loreal scale, which is fused with the prefrontal on each side, with the prefrontal extending towards the supralabials; all remaining Achalinus species known at time to occur in Vietnam ( A. ater, A. juliani, A. rufescens, and A. spinalis) have a loreal being separated from the prefrontal by a suture, which is also the case in most other Achalinus species ( A. hainanus, A. meiguensis, A. niger, and A. werneri) which thus can be easily distinguished from Achalinus timi sp. nov.

For details and further distinguishing characters see Table 5.</p><p>Besides different maxillary teeth counts, Achalinus timi sp. nov. can be distinguished from the two subspecies of A. formosanus as follows: from A. f. formosanus by having the internasal suture distinctly longer than prefrontal suture (versus internasal suture almost as long as prefrontal suture) and 25–25–23 versus 29–27–25 dorsal scale rows; and from A. f. chigirai by 23 versus 25 dorsal scale rows at posterior body and by having more ventrals and less subcaudals (170 versus 161–167 ventrals; 72 versus 96–97 subcaudals).</p><p>Furthermore, Achalinus timi sp. nov. can be distinguished from A. jinggangensis by having 25 versus 23 dorsal scale rows at midbody, more ventrals and subcaudals (170 versus 156–164 ventrals; 72 versus 51–64 subcaudals, respectively).</p><p>Etymology. We name this species after Tim N. Ziegler. As common name we propose Tim’s Burrowing Snake.</p><p>Distribution.
