TypesHolotype: BMNH (collected by A.H. Roff in 1874) 
DiagnosisDiagnosis. Liophis janaleeae differs from all other species of Liophis by the following combination of characters: scale rows 17–17–15, smooth, with one apical pit; 9 (occasionally 10) infralabials (L. taeniur us usually has 10 infralabials). There is a wide lateral black stripe on the posterior part of body that continues onto the tail, bordered above by an irregular pale line on parts of scale rows 4–6 and below by a dotted white line on the lower part of scale row three. The subcaudals are completely black or with a wide black stripe on the inner one-half of each scale row. The anterior ventrals are about equally black or yellow, but the posterior ventrals are all black or form a series of 4–5 black ventrals separated from the next series by a single yellow ventral. There are 2–4 rows of small black spots on the anterior dorsum (L. taeniurus normally has a single row of 38–48 large black spots in juveniles that fade posteriorly in adults).
