DiagnosisDiagnosis (genus). A medium sized snake in relation to members of the family measuring SVL 250–930 mm differing from most colubrid genera in lacking hypapophyses on posterior dorsal vertebrae (Fig 2) and in bearing nine maxillary teeth and the posterior-most teeth are subequal, nine palatine teeth. Dorsal scale reduction characterized by vertebral reductions, increase of scale rows posterior to neck, a single lateral reduction at midbody and regular vertebral reduc- tions in posterior half of the body. Rostral not visible from above, a small presubocular present. Eight supralabials, fourth and fifth in contact with orbit, anal undivided, 215–216 ventrals, 51– 54 subcaudals, hemipenis subcylindrical, spinose throughout and 3–4 dorsal scale row wide black longitudinal stripe running from the post nasal to the tail tip on each side on a wheat colored dorsum.

Wallaceophis gen. nov. may be distinguished from most members of the family Colubridae in lacking hypapophyses on posterior dorsal vertebrae. This condition is present in racers and whip snake of the genera Platyceps, Hemorrhois, Spalerosophis, Hemerophis, Dolichophis, Hier- ophis, Eirenis, Orientocoluber, Coluber, Macroprotodon, Bamanophis and Lytorhynchus. Walla- ceophis gen. nov. differs from these genera in bearing unique vertebral dorsal scale reductions (vs. lateral reductions in Platyceps, Hemorrhois, Hemerophis, Dolichophis, Hierophis, Eirenis, Orientocoluber, Coluber, Macroprotodon, Bamanophis and Lytorhynchus); nine maxillary teeth (vs. 15–17 in Spalerosophis, 14–19 in Platyceps, 13–16 in Hemorrhois, 17–20 in Hemerophis, 16–18 in Hierophis, 16–26 in Eirenis, 15–19 in Bamanophis); presubocular present (vs. absent in Macroprotodon, Orientocoluber, Bamanophis). The new genus is closely related to the genus Lytorhynchus based on ~3047bp of nuclear and mitochondrial gene sequences however differs from it in having vertebral dorsal scale reduction (vs. lateral in Lytorhynchus); nine palatine teeth (vs. 3–5 in Lytorhynchus). 
CommentThe species name was misspelled multiple times in this paper, with the arguably correct name “gujaratensis” appearing only on page 4, with incorrect variations on previous and later pages. 
EtymologyThe proposed generic name is a compound of two words, the first being a patronym honoring Alfred Russel Wallace for his pioneering work on biogeography and for co-discovering the theory of natural selection with a suffix ‘ophis’ (όφιB) meaning snake in Greek. Gender of the proposed generic name is masculine.
The specific epithet refers to Gujarat state in western India where the new spe- cies was discovered.
