| Diagnosis | Diagnosis: The following combination of characters distinguishes the new species from Dendrelaphis bifrenalis: shorter snout: ED 103– 114% of EN (vs 77–95%), larger eye: ED 21– 23% of HL (vs 17–20%), presence of a temporal stripe stopping just beyond the neck (vs continues behind neck), absence of black transverse dorsolateral bars on the anterior 1/4th of body (vs prominent), presence of a ventro- lateral stripe continuing up to the tail (vs stopping at the level of anal plate) and narrow and pointed snout (vs broad and flat). Furthermore a divided nasal (vs single) distinguishes the new species; the differences are shown in Figs. 8 & 9, and summarized in Tables 6 & 7 in Danushka et al. 2020. |

| Etymology | The specific epithet is a noun in the genitive case, honoring Mr. L.J. Mendis Wickramasinghe and his wife Mrs. Nethu Wickramasinghe for their remarkable contributions to the field of herpetology in Sri Lanka. Especially, Mendis Wickramasinghe‘s enormous effort in popularizing snake conservation among the general public is highly commendable. We shorten their modern name to the stem “Wickr” and formed in case of plural adding the suffix [-orum]. |
