CommentDemansia olivacea rufescens STORR 1978 and Demansia olivacea calodera STORR 1978 have been elevated to species status.

Diemenia angusticeps has been considered as a synonym of Demansia olivacea since BOULENGER 1896 until its resurrection by SHEA & SCANLON 2007.



Diagnosis. A moderately large (SVL to 676 mm) Demansia lacking dark or pale nuchal collars or dark spots on anterior ventrals, but possessing a dark transrostral streak that is usually excluded from the orbit and well-developed pale pre- and postocular bars.

Venomous! 
EtymologyAlthough not explicitly stated by Macleay, the name angusticeps is presumably derived from the Latin angustus (narrow) and -ceps (head), calling attention to the long narrow head of this and other Demansia.
