H. hikidanus differs from boydii, spinipes and dilophus by a homogeneous dorsal scalation (vs. heterogeneous) and a longer tail TL/SVL > 2.9 (vs. < 2.3); all other species with the exception of schultzewestrumi by significantly enlarged scales along the anterior edge of the gular pouch and from schultzewestrumi by smaller plates at the sides of the head (if present usually only near the angle of the mouth), largest extension < Ø tympanum (vs. present, largest extension > Ø tympanum); additionally from godeffroyi by a broader head HW/SVL > 0.131 (vs. < 0.128), a higher nuchal crest > Ø tympanum (vs. < 1/2 Ø tympanum), as well as not having the base of the tail raised (vs. raised); auritus, geelvinkianus
and nigrigularis by the presence of a row of enlarged submaxillaries (vs. absent) as well as a rounded base of gular pouch approximately near the clavicular region (vs. acuminate on chest); modestus the presence of a dorsal crest (vs. absent); macrolepis and longii by a lower number of scales between enlarged submaxillaries and infralabials, 3 (vs. 4–5) as well as smooth scales on the anterior part of the gular pouch (vs. keeled); schoedei by shorter legs HBL/SVL < 0.45 (vs. > 0.46); binotatus by a discontinuous vertebral crest on the nape (vs. continuous); bruijnii and papuensis by a larger tympanum, T/E > 0.73 (vs. < 0.73).
