DistributionSri Lanka

Type locality: Ceylon  
TypesSyntypes: BMNH 1946.1.23.21, a 610 mm male (B.H. Barnes) and 1858.2.17.19 (Higgins). 
DiagnosisDescription by SMITH 1943: “Maxillary teeth 29-32, posterior largest; snout broadly rounded; eye as long as its distance from the anterior border of the nostril; intranasals shorter than the prefrontals; temporals 1+2; 8 supralabials, 4th and 5th touching the eye; vertebrals feebly enlarged, at mid-body narrower than the outer row of scales, the posterior margin rounded or truncate. Scales in 13:13:9 rows. V. 149; C. 119-128; A. 2.” 
CommentSynonymy: SMITH (1943) synonymized D. caudolineolatus with Dendrophis effrenis, now a synonym of D. caudolineatus. Dendrophis effrenis was revalidated by Danushka et al. 2020 though.

Distribution: previously considered to occur in India (although Indian records have been assigned to another species, see Danushka et a. 2020).

Behavior: diurnal

Habitat: fully arboreal (Harrington et al. 2018)
