Description. A species of the Dendrelaphis caudolineatus group, characterized by the combination of 1) absence of black longitudinal stripes; 2) absence of a pale ventrolateral line; 3) absence of a black postocular stripe; 4) an orange stripe on the neck in live specimens (Taylor, 1922; Gaulke, 1994); 5) 173–181 ventrals (females – note that Gaulke  recorded values of 171 and 172 in two specimens of undetermined sex); 6) 104–110 subcaudals; 7) relative tail-length 0.262–0.270; 8) 6–7 temporal scales on each side; 9) 9–11 infralabials on each side; 10) 4–5 scales touching the posterior borders of the parietal scales; 11) maximum total length females 126.0 cm [VAN ROOIJEN & VOGEL 2012]
Sexual dimorphism. Sexual dimorphism could not be established because only females were included in this study [VAN ROOIJEN & VOGEL 2012].
Habitat: fully arboreal (Harrington et al. 2018), but Gaulke 1994 says “all sighted specimens of D. c. flavescens were observed on the floor of primary and secondary forest.”
Diet: SMF 75174 was kept alive in a terrarium for about 12 months, feeding on live
geckos. Locusts and mice were not taken (Gaulke 1994).
There seem to be no live photos. Gaulke 1994 says “not a rare snake. In all, 10 specimens were sighted, but as it is a very fast snake,few were caught”.
