Type locality: near Nondugl, Papua New Guinea (5°52’S, 144°46’E).  
TypesHolotype: ZSM 1965/82, paratype: ZSM 1965/89 
DiagnosisDiagnosis.– Medium–sized, slender, long–tailed species with homogeneous dorsal scalation and a discontinuous vertebral crest. Extremely large plates below the tympanum and several extremely large gulars; a row of enlarged submaxillaries present; upper part of the anterior edge of the gular pouch with enlarged scales.
H. schultzewestrumi differs from all other species by the presence of large plates on the sides of the head, maximum size of the largest scale > Ø tympanum (vs. ≤ Ø tympanum), several large gulars ≥ Ø tympanum (vs. ≈ Ø tympanum), as well as a saw–toothed anterior edge of the gular pouch consisting of enlarged scales (vs. anterior edge of the gular pouch smooth); additionally from boydii, spinipes and dilophus by a homogeneous dorsal scalation (vs. heterogeneous) and a longer tail TL/SVL > 3.0 (vs. < 2.3) (Manthey & Denzer 2006: 23).
