In dorsal view, sides of head straight, converging steadily to level of nares, snout tip between nares rather blunt. In lateral view, top of head weakly convex; margins of upper jaw (lip) concave especially anterior to the level of the TAs; ridge bearing vomeropalatine teeth just visible close to CM; lower jaw half the height of upper jaw at CM. In ventral view, mouth moderately recessed, margins of lower jaw and upper lips not much more blunt than tip of snout. Eyes not visible. TAs very slightly elevated, the elevations visible dorsally and ventrally, lie just above imaginary lines between nares and CMs, distinctly closer to CMs than to nares. Nares small, dorsolateral, circular depressions with anteroventral ovate aperture, somewhat closer to level of AM than to ST, much closer to top than to bottom of snout in lateral view, not visible from below. Teeth pointed, gently recurved, lacking serrations or flanges; elements of outer series much smaller posteriorly, monocuspid, dentaries largest, premaxillary-maxillary teeth large; vomeropalatines much smaller, more uniform in size, bicuspid, about as many in front of the anterior margins of the choanae as behind, vomerine series forming gentle arch anteromedially; distance between vomeropalatine and premaxillary-maxillary series anteriorly almost equal to projection of snout; series converging posteriorly to about half that distance, upper series extending posteriorly well (5–7 elements or more on each side) past choanae, approaching CMs, palatine series extending slightly further posteriorly. Palate moderately arched. Choanal apertures subcircular, separated from each other by twice their individual widths, anterior margins approximately level with tentacles; valves not visible. Tongue simple (no surface architecture) with broad attachment anteriorly. Nuchal region barely more massive than adjacent body. C1 shorter than C2, well-marked, NG1 and NG2 completely encircling body, bending slightly anteromedially on dorsum, NG3 incomplete ventrally; substantial TG on dorsum of C2, just visible laterally. Behind collars, 97 PAs and a small unsegmented terminal cap. AGs slightly raised posteriorly, complete or nearly so dorsally, mostly separated mid-ventrally, 31 AGs complete ventrally anterior to vent; no AGs posterior to vent on venter. First SAG present mid-dorsally on 52nd PA, all PAs behind 55th divided by mid-dorsally complete SAGs, 12 of which are complete ventrally (on PAs 84–95) anterior to vent region.

provided accounts for some 158 species, of which he was the authority for almost half (73). These and other prodigious feats of species description led to Taylor having a reputation as something of a “splitter”, and a not insubstantial number of his species have been subsequently relegated to synonyms. Although Taylor occasionally explicitly held back from describing possible new species for variant specimens, this was the exception rather than the rule.

The new species is known from only a single specimen collected more than 70 years ago and, given that there have been no dedicated attempts to recollect or otherwise survey its status in the wild, it must be considered data deficient for conservation purposes. Targeted fieldwork is needed to shed light on the distribution and abundance of this very poorly known species, and to provide material for both morphological and molecular systematic study.
