| Distribution | Malaysia (Borneo) Type locality: Nanga Segerak (1° 25’ N, 112° 00’ E), 245 m elevation, headwaters of the Engkari River, Lanjak-Entimau Wildlife Sanctuary, Lubok Antu District, Second Division, Sarawak, Malaysia. |
| Reproduction | ovovivparous |
| Types | Holotype: ZRC (Zoological Reference Collection, Department of Zoology, National University of Singapore) |
| Diagnosis | Diagnosis: Cylindrophis engkariensis, new species, belongs to the genus Cylindrophis Wagler, because of the following combination of characters: small head not distinet from neck, covered with large symmetrical shields; the nostril in a single nasal, with no loreal or preocular scale; a mental groove present; tail short and blunt (De Rooij, 1917). The head scutellation and the smooth iridescent hody scales are typical of Cylindrophis. However, Cylindrophis engkariensis is different from Cylindrophis sensu stricto (see Cundall et al., 1993) in the number of mid-body scale rows, e.g. 17 in the former vs. 19-23 in the latter. Furthermore, unlike other species of Cylindrophis, the ventrals of Cylindrophis engkariensis are indistinguishable in width from the dorsals. Cylindrophis engkariensis also possesses a unique colour pattern of small, white, irregularly shaped paravertebral spots, and the tail dark (black) dorsally, and lighter ventrally with dark mottling. In contrast, Cylindrophis rufus is characterised by orange bands partially encircling a black body; an incomplete orange ring encircling the posterior portion of the head, and a broad orange band encircling the tail. Equally contrasting with the pattern of C. engkariensis is the BMNH holotype of Cylindrophis lineatus, which has (in alcohol) a yellowish head with a faint dark rostral spot, alternating dark and yellow bands along the sides, a irregular dark longitudinal stripe along the side, running the length of the body, two light paravertebral stripes and a middorsal dark stripe.
