Rhinophis erangaviraji

The preferred natural habitats of R. erangaviraji are forest and grassland, at altitudes of 900–1,300 m (3,000–4,300 ft), but it has also been found in disturbed areas such as tea plantations and home gardens.^[1]

The species R. erangaviraji is easily distinguished from other shieldtails in Sri Lanka through colour variations. The head is black, with yellow irregular spots. The eyes are black. The body is black dorsally, with some yellow irregular patches. The ventral surface is cream-colored, with a stripe running along the vent region. The tail shield is black with small spines on it, which help to gather sand particles. Juveniles are similar to adults, but with a darker head and a paler body.^{[citation needed]}

The largest paratype specimen has a snout-to-vent length of 29 cm (11 in).^[2]

R. erangaviraji is terrestrial and fossorial, burrowing as deep as 1 m (3.3 ft) in loose soil.^[1]

Mating of R. erangaviraji may occur during July and August, as juveniles can be seen from October to January.^{[citation needed]}

The specific name, erangaviraji, is in honour of Sri Lankan zoologist Eranga Viraj Dayarathne, who was an Instructor of the Reptiles group of the Young Zoologists’ Association of Sri Lanka, and Department of National Zoological Gardens.^[2][3]
