Phalotris shawnella

Phalotris shawnella has a brick-red head dorsally and uniformly brownish-red supralabials. The underside of the head is red-orange, with a grey hue to the first three infralabials and whitish chin shields. Behind the head, there is a broad yellow collar on the dorsum, with the collar fading towards the side to be replaced by a thinner black collar. Both collars are absent on the underside. The body is brick-red dorsally, with a faint thin black vertebral line along its length that fades upon reaching the tail. There are broad, black to brownish-black lines along the sides along the length of the body, from the collar to the tip of the tail. These bands are uniformly 3–3.5 scales wide on the body, narrowing slightly to 2 scales wide on the tail. The underside of the body is red-orange, with small black, diffuse blotches on the edges of some of the ventral scales. Phalotris shawnella can be distinguished from all species in its genus outside the nasutus group by its pointed snout with a prominent rostral shield and the fusion of the second and third temporal plates. …
