CommentDiagnosis. A medium-sized Demansia (maximum SVL 636 mm) with a pale-edged dark nuchal collar (obscure in adults), prominent transrostral streak extending to orbit, prominent pale preocular and postocular bars, the latter not (or barely) reaching throat due to contact or near contact between dark teardrop marking and nuchal collar (the contact of the dark markings may be less intensely dark than the main pattern elements; Fig. 20), and a dark blue-grey belly, at least posteriorly.


Venomous! 
EtymologyPresumably from the Latin torquatus (collared), and alluding to the nape markings.
